Many TLAs: MTP MSC FS SD SDFat LittleFS UsbMSCFat to work with each other 8)

Aargh and :D

Sometimes it is the simple things!

Like the right number of msc objects!

I pushed up a change in my temporary branch...

Sorry in this push, that I removed compiler stuff for MSC examples and accidentally pushed up my Sublimetext project/worksspace and build file... When I merge the stuff back over to the next higher
version I won't include these changes...

But the main change was:
From: MSCClass msc[USE_MSC_FAT];
To: MSCClass msc[USE_MSC_FAT_VOL];


I still have hack in place that does not get the correct free space for partitions > 3gb... Will work on that again soon.


But if anyone is still playing you might try picking that little change up and see if it works better for you.

It's those little details that get me to. You know, the obvious ones that are so obvious you never notice them until they bite you:)
Anyway tonight I will download your latest and hopefully this weekend I can play with it. I tend to keep several backups of anything I do a major change on. That's why I have the three computers and several backup drives. I am tempted to try using Windows 10 just to be aligned with you guys but am afraid to use it after the major lose of my work of several years due to ransom ware. This being Window 7 with antivirus protection. I do not want to spend money on antivirus programs and every year and fight anti virus settings which is what I did before and still lost. Maybe things have changed with Windows 10? Have not had the time to explore it:)

Morning all

Gave the change quick try using a hub plus 1 old thumb drive formatted for 2GB and the 32GB SDCard/Adapter. Seems to come up a lot faster, and looks like it picks up the 2 drives and all the partitions. 3 partitions on the 32GB Card (1 partition is broke as I mentioned before so it bypassed that one) plus the the Thumb drive:

@mjs513, now We need to find way to update the free/used space.

And need to test unplugging a device and do we properly remove the partitions...

Also I again want to try updating the StorageIDs... They are currently not to specification. The high word should be storage and low word is sort of sub-storage...
I am curious if that will allow the names to show up on Linux and the like...

Also for example if you look at some of the messages/events like:
G.2.6 StoreRemoved
Event Code: 0x4005
Parameter 1: StorageID
Parameter 2: None
Parameter 3: None
The indicated stores are no longer available. The opposing device may assume that the StorageInfo datasets and ObjectHandles associated with those stores are no longer valid.
The first parameter is used to indicate the StorageID of the store that is no longer available. If the store that has been removed is only a single logical store within a physical store, the entire StorageID shall be sent, which indicates that any other logical stores on that physical store are still available. If the physical store and all logical stores upon it are removed (for example, removal of an ejectable media device that contains multiple partitions), the first parameter shall contain the PhysicalStorageID in the most significant sixteen bits, with the least significant sixteen bits set to 0xFFFF.

Which in the case of one of our MSC drives being removed this feels more appropriate...
 
@KurtE
Ran a couple of test cases just out of curiosity.

First case was as described in my previous post which we know worked. But then I unplugged the SDcard adapter and plugged it back it - it seemed to work but I had to do a refresh to refresh to get all the partitions back again:
Code: 
*MTPD::send_Event(4005) a
*MTPD::send_Event(4005) b
*MTPD::send_Event(4005) c

Second case was just restarting Teensy with the thumb drive in and then plugging in the SDCard adapter. Of course it read the thumb drive fine and when I plugged in the SDCard-Adapter it looks like it recognized it but MTP lost the drives/partitions in win explorer:

There is going to be another issue that not sure how it can be resolved - at least I couldn't figure it out. The problem is going to be formatting partitions. Not sure SDFat is set up to do that? When I tried it with just a SD Card in the T4.1 it formatted the whole card and not just the partition but then again I could have done it wrong.

Yes So far I have only put in code for formatting of LittleFS stuff, have not dealt yet with FAT file systems... So far no API or methods that I know of for it, only the sketches in the SDFat library.

Maybe sometime we should try adapt one or more versions of it to partition?

Have not gotten much done today, distracted with other things

Can probably be adapted but would have to do something like you did for volume - create locale copy.
 
@mjs513, that is sort of what I figured.

@all - Keep wondering about how SLOW the getting free space is

I can imagine that it could probably be sped up a lot, but not sure how doable it is without major surgery everywhere.

That is, the code for fat looks like:
Code: 
int32_t FatPartition::freeClusterCount() {
#if MAINTAIN_FREE_CLUSTER_COUNT
  if (m_freeClusterCount >= 0) {
    return m_freeClusterCount;
  }
#endif  // MAINTAIN_FREE_CLUSTER_COUNT
  uint32_t free = 0;
  uint32_t sector;
  uint32_t todo = m_lastCluster + 1;
  uint16_t n;

  if (FAT12_SUPPORT && fatType() == 12) {
    for (unsigned i = 2; i < todo; i++) {
      uint32_t c;
      int8_t fg = fatGet(i, &c);
      if (fg < 0) {
        DBG_FAIL_MACRO;
        goto fail;
      }
      if (fg && c == 0) {
        free++;
      }
    }
  } else if (fatType() == 16 || fatType() == 32) {
#if 0    
    Serial.printf("###FatPartition::freeClusterCount: FT:%u start:%u todo:%u\n", fatType(), m_fatStartSector, todo);
    Serial.printf("    m_sectorsPerCluster:%u\n", m_sectorsPerCluster);
    Serial.printf("    m_clusterSectorMask:%u\n", m_clusterSectorMask);
    Serial.printf("    m_sectorsPerClusterShift:%u\n", m_sectorsPerClusterShift);
    Serial.printf("    m_fatType:%u\n", m_fatType);
    Serial.printf("    m_rootDirEntryCount:%u\n", m_rootDirEntryCount);
    Serial.printf("    m_allocSearchStart:%u\n", m_allocSearchStart);
    Serial.printf("    m_sectorsPerFat:%u\n", m_sectorsPerFat);
    Serial.printf("    m_dataStartSector:%u\n", m_dataStartSector);
    Serial.printf("    m_fatStartSector:%u\n", m_fatStartSector);
    Serial.printf("    m_lastCluster:%u\n", m_lastCluster);
    Serial.printf("    m_rootDirStart:%u\n", m_rootDirStart);
    Serial.printf("    m_bytesPerSector:%u\n", m_bytesPerSector);
#endif
    sector = m_fatStartSector;
    digitalWriteFast(0, HIGH);
    while (todo) {
      digitalWriteFast(1, HIGH);
      cache_t* pc = cacheFetchFat(sector++, FsCache::CACHE_FOR_READ);
      digitalWriteFast(1, LOW);
      if (!pc) {
        DBG_FAIL_MACRO;
        goto fail;
      }
      n =  fatType() == 16 ? m_bytesPerSector/2 : m_bytesPerSector/4;
      if (todo < n) {
        n = todo;
      }
      if (fatType() == 16) {
        for (uint16_t i = 0; i < n; i++) {
          if (pc->fat16[i] == 0) {
            free++;
          }
        }
      } else {
        for (uint16_t i = 0; i < n; i++) {
          if (pc->fat32[i] == 0) {
            free++;
          }
        }
      }
      todo -= n;
    }
  } else {
    // invalid FAT type
    DBG_FAIL_MACRO;
    goto fail;
  }
  digitalWriteFast(0, LOW);
  setFreeClusterCount(free);
  return free;

 fail:
  return -1;
}
Basically it reads one 512 byte sector, and looks through each fat sector and on these larger partitions like 4gb, you have to read thousands of these sectors.
It then scans the 512/2 or 512/4 cluster markers in that sector and counts the so many that have specific value and then sets up to read the next sector.

This read of the next sector includes the write a USB command out to do the read request, and then wait for the host to respond and send me back the 512 bytes...

So it outputs a command and waits for response for each sector... Question is can one rework the cod that it knows that it is going to read a lot of these sectors and have the code instead of read one sector at a time, maybe it has another buffer like 4KB or 8KB, which it can read in multiple sectors in one sitting. Or better yet maybe it can say to read all of the sectors in and use multiple transfer objects, each with it's own buffer and have scan a buffer while the USB system is filling the next one...

Again I know some of this is doable, from other USB devices. Just not sure how much work it would be to all parts of the system to do this?

But wondering if it would be faster and by how much.
 
@all - I think I will try a hack to see how much if any the freeClusterCount code could be sped up.

What I am thinking of doing is start off with Fat (so Fat16/32). I am curious of how fast is it already for large exFat partition? Will try one of my 8GB disks to format the whole thing for exFat and see what it does.

But assume, in the MSC code, that I trap the request for the freeClusterCount.

Then see in the USBHost_t36 code (MasStorageDriver.cpp)

Maybe have a call like:
Code: 
uint8_t msController::msReadBlocks(
									const uint32_t BlockAddress,
									const uint16_t Blocks,
									const uint16_t BlockSize,
									void * sectorBuffer)
That calls off to msDoCommand, but this version maybe works differently. Instead of maybe one buffer and/or maybe the buffers are part of the library...
And then the caller puts in a Callback function to be called when each sector is received...

So the idea would be, for the freeClusterCount code to compute how many sectors it needs to read, and then setup an ISR to receive each buffer, in the same way we process things like USB Serial or RAWHID...
So then the version of doCOmmand, would queue up multiple input transfer objects, so when one is received, it will be processing the next one if any data comes in during the processing of the previous one.

I think it sounds doable. Will be interesting to see if it really does speed it up.

Thoughts?
 
So far I have done a really dirty version of the FatPartition getFreeClusterCount code as part of the VolumeName.ino sketch.

I think most if not all of the changes are in the two Github Projects:

USBHost_t36 I added a new method to the class for call backs on reading multiple sectors: https://github.com/KurtE/USBHost_t36/tree/MSC_read_sectors_cb
And updated the branch/fork; https://github.com/KurtE/UsbMscFat/tree/VolumeName_SD

I do think it is showing some progress, not sure yet on how to cleanly implement it...

And note I have not done ExFat here yet...

Debug output, minus the LS stuff...

So for example the Fat32 big volume, took over six seconds by the FatPartion call: 6096623
Actually slightly cheating as that time included the call to get the total number of clusters which very slight:
And with my call back code it took about .5 seconds.. So about 12 times faster....

The Fat16 smaller one, api took: about .2 seconds by api and about .017 seconds, again not bad...
The hacky code looks like:
Code: 
typedef struct {
  uint32_t free;
  uint32_t todo;
  uint32_t clusters_per_sector;
} _gfcc_t;


void _getfreeclustercountCB(uint32_t token, uint8_t *buffer) 
{
  digitalWriteFast(1, HIGH);
  _gfcc_t *gfcc = (_gfcc_t *)token;
  uint16_t cnt = gfcc->clusters_per_sector;
  if (cnt > gfcc->todo) cnt = gfcc->todo;
  gfcc->todo -= cnt; // update count here...

  if (gfcc->clusters_per_sector == 512/2) {
    // fat16
    uint16_t *fat16 = (uint16_t *)buffer;
    while (cnt-- ) {
      if (*fat16++ == 0) gfcc->free++;
    }
  } else {
    uint32_t *fat32 = (uint32_t *)buffer;
    while (cnt-- ) {
      if (*fat32++ == 0) gfcc->free++;
    }
  }

  digitalWriteFast(1, LOW);
}

uint32_t GetFreeClusterCount(USBmscInterface *usmsci, PFsVolume &partVol)
{

  FatVolume* fatvol =  partVol.getFatVol();
  if (!fatvol) return 0;

  _gfcc_t gfcc; 
  gfcc.free = 0;

  switch (partVol.fatType()) {
    default: return 0;
    case FAT_TYPE_FAT16: gfcc.clusters_per_sector = 512/2; break;
    case FAT_TYPE_FAT32: gfcc.clusters_per_sector = 512/4; break;
  }
  gfcc.todo = fatvol->clusterCount() + 2;

  digitalWriteFast(0, HIGH);
  usmsci->readSectorsWithCB(fatvol->fatStartSector(), gfcc.todo / gfcc.clusters_per_sector + 1, 
      &_getfreeclustercountCB, (uint32_t)&gfcc);
  digitalWriteFast(0, LOW);

  return gfcc.free;
}
You can also see the differences by the LA. I have line 0 with the whole time in the API... and the second line going around either the time to read each sector by API or callback for each sector read:

screenshot.jpg
I set timing markers around each time of the sections for get the free cluster count: First was call to FatPartion, the other my hack... Dito for 2nd volume.
 
I took my quad partition SD to my old PC and it did not FAULT on plugging it in - then I removed the 4th Part that was ExFat with an odd partition number. I'll get that in a Teensy with updated libs soon.

:) : Was very odd each time I added a partition to that SD on this new PC it would FAULT to BSOD ... actually green now and restart ... I swapped single 16GB to twin 16's ... wonder if that could be an issue as it says memory?
 
@KurtE Can't wait to play with this. I had a branch of (MSC-non-blocking) that I was playing with just to try learn about buffering reads and writes to MSC. I was using CircularBuffer from @tonton81 and @mjs513 and also using attachYield() form @luni. It is working but uncontrollable for anything other than direct sector reads or writes. Hopefully this weekend I can check it out what you you have done:)

I remember back when I was using the Teensy 2.0++ and an SD card I had a Fat32 driver I was using. Can't remember which one at this time. Anyway, doing a disk free check could be done two ways. It could do it the slow way and read through the data sectors or there was something kept in the FAT some where that was updated with the free space on the card. I just can't remember what it was. I need to go back and see if I can find it. There was a big difference in speed between scanning the FAT and reading the FAT report.

It looks like the 4th partition is not reading the MBR correctly. In @defragsters test it was for an extFAT partition - in my case the 4th partition is a FAT16 but not reading FAT-type correctly.

As a quick test I change the IP look so it reads ip<6 instead of ip<5:
Code: 
FAT32:	1,80,0x20,0x21,0x0,0xC,0xC2,0x22,0x20,2048,524288

According to this FAT16 is on partition 5? Have to do some checking.
 
Based on the MBR issue in post #64 looks like there really was a bit of space unallocated between partition 3 and 4 on my drive. I deleted part 3 and 4 and recreated them and now the MBR is correct for what I wanted:
Code: 
msc # Partition Table
	part,boot,bgnCHS[3],type,endCHS[3],start,length
FAT32:	1,80,0x20,0x21,0x0,0xC,0xC2,0x22,0x20,2048,524288
FAT32:	2,0,0xC2,0x23,0x20,0xC,0xFE,0xFF,0xFF,526336,16564224

FAT16:	4,0,0xFE,0xFF,0xFF,0xE,0xFE,0xFF,0xFF,245542912,4194304
@defragster - you may be seeing the same thing as I did on your drive - may be a bit of unallocated space between your partitions.
 
Morning all,

It is interesting with the Fat tables. Knowing what type of partition each one is, is done by SDFat code. My PFsFat classes are again just FsFat class with a couple things now:

it allows me to pass in the partition number to the begin... That was it until yesterdays, hack which I added members to retrieve the Fat or ExFat object.

What the begin does, is to first cast (that funky new) some internal storage to be an ExFatVolume and then try to call begin on it with the partition number. If that returns success we are done.
If that fails it casts the storage (again new) to FatVolume and again call begin.

So if we are failing (and I have not screwed up with to few of the MSC objects), than the underlying fat code did not like the volume. So may have to track down why.

Also note, this partition code is restricted to only handle the primary partitions (1-4), and it knows nothing about extended partitions. Probably nothing we would want to tackle!

Sounds like something was screwed up as there is no room in the MBR for a 5th?
Code: 
const uint16_t MBR_SIGNATURE = 0xAA55;
const uint16_t PBR_SIGNATURE = 0xAA55;

typedef struct mbrPartition {
  uint8_t boot;
  uint8_t beginCHS[3];
  uint8_t type;
  uint8_t endCHS[3];
  uint8_t relativeSectors[4];
  uint8_t totalSectors[4];
} MbrPart_t;
//-----------------------------------------------------------------------------
typedef struct masterBootRecordSector {
  uint8_t   bootCode[446];
  MbrPart_t part[4];
  uint8_t   signature[2];
} MbrSector_t;
If my early morning math is correct, the MbrSector_t adds up to 512 bytes.

But again maybe not enough coffee yet!

To be honest the only reason I even tried 5 partitions was I thought maybe there was something wrong with the indices.

Was looking at that structure this morning as well since I wasn't sure how the MbrPart_t was set up. Not sure why it worked unless since the partition failed it didn't count it so it allowed an extra partition - sounds strange doesn't it?

So far I have done a really dirty version of the FatPartition getFreeClusterCount code as part of the VolumeName.ino sketch.

I think most if not all of the changes are in the two Github Projects:

USBHost_t36 I added a new method to the class for call backs on reading multiple sectors: https://github.com/KurtE/USBHost_t36/tree/MSC_read_sectors_cb
And updated the branch/fork; https://github.com/KurtE/UsbMscFat/tree/VolumeName_SD

I do think it is showing some progress, not sure yet on how to cleanly implement it...

And note I have not done ExFat here yet...

Debug output, minus the LS stuff...

Code: 
msc # Partition Table

FAT32:	1,0,0x4,0x1,0x4,0xB,0xFE,0xC2,0xFF,2048,8192000

So for example the Fat32 big volume, took over six seconds by the FatPartion call: 6096623
Actually slightly cheating as that time included the call to get the total number of clusters which very slight:
And with my call back code it took about .5 seconds.. So about 12 times faster....

The Fat16 smaller one, api took: about .2 seconds by api and about .017 seconds, again not bad...
The hacky code looks like:
Code: 
typedef struct {
  uint32_t free;
  uint32_t todo;
  uint32_t clusters_per_sector;
} _gfcc_t;


void _getfreeclustercountCB(uint32_t token, uint8_t *buffer) 
{
  digitalWriteFast(1, HIGH);
  _gfcc_t *gfcc = (_gfcc_t *)token;
  uint16_t cnt = gfcc->clusters_per_sector;
  if (cnt > gfcc->todo) cnt = gfcc->todo;
  gfcc->todo -= cnt; // update count here...

  if (gfcc->clusters_per_sector == 512/2) {
    // fat16
    uint16_t *fat16 = (uint16_t *)buffer;
    while (cnt-- ) {
      if (*fat16++ == 0) gfcc->free++;
    }
  } else {
    uint32_t *fat32 = (uint32_t *)buffer;
    while (cnt-- ) {
      if (*fat32++ == 0) gfcc->free++;
    }
  }

  digitalWriteFast(1, LOW);
}

uint32_t GetFreeClusterCount(USBmscInterface *usmsci, PFsVolume &partVol)
{

  FatVolume* fatvol =  partVol.getFatVol();
  if (!fatvol) return 0;

  _gfcc_t gfcc; 
  gfcc.free = 0;

  switch (partVol.fatType()) {
    default: return 0;
    case FAT_TYPE_FAT16: gfcc.clusters_per_sector = 512/2; break;
    case FAT_TYPE_FAT32: gfcc.clusters_per_sector = 512/4; break;
  }
  gfcc.todo = fatvol->clusterCount() + 2;

  digitalWriteFast(0, HIGH);
  usmsci->readSectorsWithCB(fatvol->fatStartSector(), gfcc.todo / gfcc.clusters_per_sector + 1, 
      &_getfreeclustercountCB, (uint32_t)&gfcc);
  digitalWriteFast(0, LOW);

  return gfcc.free;
}
You can also see the differences by the LA. I have line 0 with the whole time in the API... and the second line going around either the time to read each sector by API or callback for each sector read:

View attachment 23933
I set timing markers around each time of the sections for get the free cluster count: First was call to FatPartion, the other my hack... Dito for 2nd volume.

@kurtE - just downloaded your changes and after running some errands I can't wait to try them out. I noticed that you changed the print and println's back to Serial.printf's again. @Paul had asked me to change these to print and println before the next beta release for debug reasons. I guess I am a little confused.

Thanks.

I believe there are two parts here.

Master Boot Record format of disks (MBR) which is I think the only style of disks that the Partition stuff built into SDFat library supports, The MBR only has room for 4 partitions. But Windows also supports the GPT style of disks with Windows 10 (and 8.?). Not sure how many partitions it supports.

But even with MBR, one can have more partitions, by using the idea of Extended Partition. That is one (or more) of the partitions in the MBR can be an Extended partition, which in turn this extended partition can then be divided up into more partitions... Used to do this way back when probably when there was only Fat16 or maybe Fat12...

But the SDFat code I don't believe supports GPT nor extended partitions.

Sorry I maybe merged with the wrong version of the changes... Mainly the only thing I meant to play with with some of the messages was to add in more information, like this pointer or the like as when you have multiple ones to help figure out who is calling.

Even by using an extended partition which can hold other partitions, I still believe that the total number of partitions on an MBR formatted drive is 4.
A GPT partition can be formatted with up to 128 drives.

Thanks, The SDFat library code is not setup to handle GPT... So not sure if anyone will look at adding it to the MSC stuff...

@all Thought about more hack for exFat free clusters, but the main code appears to be fast enough:
Created a second Thumbstick with 4 partitions.

^^^^    After usbDriveBegin
PFsVolume::begin(20002030)
ExFatVolume::begin(20002030 1 1
USB drive 1 is present.

Will try to cleanup the messages again to be back to the USBHost_t36 format of messages. Note: In some of the different object types we have a mix of either using the
Setting withing the Header file: //#define USBHOST_PRINT_DEBUG

and some that I have specific for a class, where we turning all the whole library debug ends up swamping you with too much stuff..

No Joy. Went to old machine that doesn't fault on partitioning. Deleted #3 and #4 and recreated them. Same result:
Code: 
msc # Partition Table
	part,boot,bgnCHS[3],type,endCHS[3],start,length
FAT32:	1,0,0x20,0x21,0x0,0xC,0xFE,0xFF,0xFF,2048,16777216
exFAT:	2,0,0xFE,0xFF,0xFF,0x7,0xFE,0xFF,0xFF,16779264,33554432
FAT32:	3,0,0xFE,0xFF,0xFF,0xC,0xFE,0xFF,0xFF,50333696,65536000
pt_#15:	4,0,0xFE,0xFF,0xFF,0xF,0xFE,0xFF,0xFF,115869696,128407552
PFsVolume::begin(200047f0)

Of course I made #3 32000 in size so maybe that does leave a void before #4 can start in the same way it did before. Will redo later not using 'marketing megabytes' - but a real multiple of 4KB ... 32768 perhaps

I tried the ip<6 and it wouldn't compile as there is a fixed array somewhere that broke the build?
 
@KurtE - Just downloaded and tested your changes. Man that is impressive:) All this this time I have been trying to do what you just did with minimal success. I wonder if we could do something similar with MSC writes? I will be studying the code.

Yes, I agree. It produces a heavy spew of info that makes it hard to isolate the info you are looking for. Maybe setup different levels of verbosity. What I added was just to isolate methods where lockups would happen. Maybe not needed.
