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...

Mine is on a FedEx truck to be delivered in town today... It will probably be several days before I go into town to pick it up.

My guess (and it is only a guess) is they have been waiting for the bootloader chip (https://www.pjrc.com/store/ic_mkl02_t4.html) Which I think still has a limit of 10...

@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...

I was sort of curious about what ever happened to this project as well as the other Controller board that in another thread, that was made at one point for one of the PrintrBot models. As I still have not fixed my...

Sorry I know nothing abot scones or the like, so not sure how much help I will be... But one thing stands out is: ARDUINO_TEENSY_MICROMOD That is for a non-existent board that is rummer to be coming. You might want...

@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...

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...

@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...

I know playing around with MTP and the like, I believe if you do all writes in units of sectors or clusters, it can run a whole lot faster. For example I know it was a lot faster with 4K blocks than when I dumped USB...

Always hard to know without a lot of additional information. Could be simply either overrunning the display with data or... Could be the Serial buffer size, and you have more data on Serial than will fit in the data...

Sorry, this is probably a question that maybe only Paul can answer, But my gut tells me that you may not be able to do this. That is the IMXRT1060RM section 42.2.1 mentions: Up to 8 bidirectional endpoints per each...

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...

It should be in both Teensy3 and Teensy4 branches. And they are identical up on github, so you should be able to simply copy the one from the Teensy3 directory to the Teensy4 directory... Or install the latest beta...

It will be interesting, as I believe it is just a beta that has been released. Also as it is a complete different platform, it will be interesting to see if/when Paul adds support.

@all - I may take break from this for rest of day. Then I may try to see if I can reduce the number of abstractions and the like and get it to work... That is how much different does the VolumeName code and the MTP...

Ok, I changed that test sketch like: // Function to handle one MS Drive... void procesMSDrive(uint8_t drive_number, msController &msDrive, UsbFs &msc) { Serial.printf("Initialize USB drive..."); cmsReport = 0;...

For the heck of it, to get another data point I am going to step back and play with the VolumeName sketch, and instead of processing one partition at a time, I am going to try to open up all partitions (up to 4) and...

Sorry just got back: It gets sort of interesting, I turned on the debug code in MassStorageDevice(USBHost) Not the big debug turn on, but one specific to this class:#define DBGprint 1 I also edited a lot of the...

As you mentioned, it all is real strange... I have been off doing some other stuff for a bit! Will try to debug some more.

Right now I am looking into the file USBFat.h code: at: template <class Vol> class UsbBase : public Vol { public: //---------------------------------------------------------------------------- /** Initialize...

It might be a problem with my mbr dump code, it is pretty big hack, I try to call the read sector directly... bool mbrDmp(msController *pdrv) { MbrSector_t mbr; // bool valid = true; if (pdrv->msReadBlocks(0,...

Thanks @mjs513 I understand what you are saying, but so far not sure where the connection is made: USB Drive Inserted msc # Partition Table part,boot,bgnCHS,type,endCHS,start,length...

I have added some additional debug code: So far I pushed up a few debug output edits to the Msc... project in the branch: https://github.com/KurtE/UsbMscFat/tree/VolumeName_SD A new MTP branch based off my other...

Yet another new day :D I have been playing with the MTP stuff, with partitions... And pulling out a fair percentage of the few hairs I have left :D I have hacked my way through to try to support N USB drives...

Again hard to know what is going on without details about the display and your wiring and... Is it this one: http://www.lcdwiki.com/2.8inch_SPI_Module_ILI9341_SKU:MSP2807 Which is another ILI9341 display? Again...

So far this one looks like it does not want to give up it's secrets! That is it is not giving any clue by device class, subclass nor protocol. 0s for the device and 0xff for interface. So probably vendor specific. ...

Hi Frank, Not sure the second one has HID or not... But again maybe try plugging it into T3.6 or T4.x with one of the USBHost_t36 examples like I mentioned. And at about line 62 in USBHost_t36.h uncomment the...

Yes Happy 51st Birthday... I think I remember back to then :D Have a great day!

Again as you mentioned maybe, as I added the ability to pass through the partition number on that begin, that maybe I should just try that and maybe again only need to object types still. Will try... Probably easier...

@mjs513 and @wwatson - Yes I think it would be a good place. But right now I am trying to rethink some of the integration of the MSC stuff into MTP... Trying to decide how far to try to take. Things like: If we...

Quick follow on: I just pushed up changes into my branch: https://github.com/KurtE/UsbMscFat/tree/VolumeName_SD To hopefully have the MSC wrappers for the files/volume now call into the new PFs... stuff. Including...

Morning all (or time in your part of the world), Starting to play with MTP again... First off: Integration question, probably for @PaulStoffregen. In an SdFat-beta project issue conversation with Bill about...

Looks maybe like this one? https://www.amazon.com/JahyShow%C2%AE-DVB-T-RTL2832U-Receiver-Compatible/dp/B01H830YQ6/ref=sr_1_8?dchild=1&keywords=RTL2832&qid=1614606952&sr=8-8

Hi Frank, It looks like this device is a HID (Human Interface Device) like mouse, some keyboard... There is an example sketch under USBHost_t36 HIDDeviceInfo that is setup to dump a lot of data in the way that I...

Just pushed up a new branch off of main which I synced back up: https://github.com/KurtE/UsbMscFat/tree/VolumeName_SD It now shows Volume information about SD Card as well: ^^^^^^^^~FsVolume::begin(20001f30) ...

@mjs513 Long Pauses are often the trying to compute the used or free space... As it walk billions and billions of ... Probably it for today. Probably tomorrow will look into MTP again with these changes. I am...

Maybe... But then there is also MTP with @WMXZ and the like... Quick fyi - right after the merge, I updated the sketch again, such that you can dump the MBR for both USB devices as well as SD Cards... I pushed...

Try syncing again. I thought I had disabled that new... Turned out I had disabled the one in SDFat library instead :o

@all, again not sure if best to mention here or in the MSC thread... But I just pushed up a new Branch of the UsbMscFat library... https://github.com/KurtE/UsbMscFat/tree/PFsLib Where I completely duplicated the...

Sounds good! Will take in. Right now I am trying to make a version of the fsFat which is partition friendly. Running into a few compile issues. Will let everyone know if I have any luck.

Actually I received a response on github from Bill... Now there is not a leak as the new is not actually allocating memory... As the code like: m_fVol = new (m_volMem) FatVolume; is actually just assigning the...

I sort of started a thread a little bit ago: https://forum.pjrc.com/threads/66338-Many-TLAs-MTP-MSC-FS-SD-SDFat-LittleFS-UsbMSCFat-to-work-with-each-other-8) Where I was maybe setting up for some integration stuff... ...

@wwatson - Sounds great. @all as I mentioned over in the MTP thread (https://forum.pjrc.com/threads/43050-MTP-Responder-Contribution?p=271721&viewfull=1#post271721) I am playing around with seeing about the...

@mjs513 - Yep I am also thinking a smaller test with fewer Storage types would be nice and/or split some of them into multiple tabs... And yes right not I am still playing with the MSC multi partition sketch...

Glad you found the issue... :D Wonder what is different between T3.x and T4.x? Or does something in your interrupts also touch the Analog? Sounds like maybe need test case to see and maybe the core code needs...

@all - Sometimes hard to know which thread to discuss things like integration of MTP amd MSC... and the like. I am going to try doing some additional changes to my branch of the code to add some more support for...

Thanks @mjs513 will probably look more in the morning. Today I also hacked up that function some more that printed that data, and used digital Write high/low with pin 0 for the whole duration and pin 1 around each...

@defragster and @mjs513 I am sort of curious about fragmentation works ;) For the Fat32 volume: I mucked up the beginning of the method most all of the class variables int32_t FatPartition::freeClusterCount() {...

Full current sketch, Note I commented out the earlier calls to get sizes... Waiting up to 5 seconds for USB drive 1 ^^Waiting up to 5 seconds for USB drive 2 ^^^^^^^~~~~:(Initialize USB...

So I tried adding in the above test sketch currently just to the FAT16 and FAT32 section code like: for (uint8_t i = 1; i < 5; i++) { switch (partitionTable) { case 11: case 12: { ...

Maybe the code in the sketch is wrong... It is not applying the partition... I am going to move those calls into the sections by partition type and see what I get... Looks like we crossed posted. I am going to...

Something does not appear to be working correctly at all with the freeClusterCount: int32_t FatPartition::freeClusterCount() { #if MAINTAIN_FREE_CLUSTER_COUNT if (m_freeClusterCount >= 0) { return...

@all - Another quick question: while starting to look at why the free space is TAKING SOOOOOOOO LLLLOOONNNGGG I noticed in the SDFat code:...

Quick note: I am thinking it might make sense to add the VolumeName.ino as an example sketch to maybe MscFS.h project. That way we can all keep track of it? Make sense?

Morning, Try picking up the latest UsbMSCFat project - I added a hack into it that if you ask for the Used size, twice (or more) it remembers the first call to it, which we do as a debug message at the time we add...

Thanks @defragster, I updated to your version. I ran again, still real slow on my older thumb drives: Waiting up to 5 seconds for USB drive 1 ^^Waiting up to 5 seconds for USB drive 2 ^^^^Initialize USB...

Just an FYI: I updated the Volume name sketch to also print out the total size and used size sort of plus elapsed time to get them for the different partitions: // VolumeName.ino // An example of how to retrieve...

@mjs513 which code fragment... MSC or MTP... So far in MTP I have not converted the main code to try to do anything with partitions, other than so far I am printing them out and I am able to get the first volume ID. ...

Might really help to understand what exactly is your setup? Windows? Linux? MAC? ... What version of Arduino are you running? What version of Teensyduino are you running? Anything changed on your machine, like...

@wwatson - not sure, about NTFS here. It looks like both partitions have type=7 which I believe is exfat. although looking at:https://en.wikipedia.org/wiki/Partition_type It looks like type of 7 could be either. ...

Any luck? Looks a bit complicated to jump in... I prefer easier things like MSC and MTP :D Is it easy to setup and see failure when you don't have the hardware? Steps, and what to see when it fails versus OK? ...

Updated to fix the Fat16, also implemented a one call to find volume label. And did some more gratuitous changes to have a function called by loop to process a drive, as to not need to reproduce it for more drives......

Another quick note: I updated my sketch to the last one @defragster and found it was using the old non working Fat16 code. i.e. the one that was reading the boot sector and appears to always be: NO NAME Will fix and...

Good morning again: Just for the fun of it you might try adding the asm("dsb"); somewhere... The reason I mention it, I have been bit several times where ISR gets triggered multiple times for the same interrupt....

Some More not fleshed out thoughts on MSC and Partitions and FS... I first off think it will be great all of the pieces in place and part of Teensyduino! What I am sort of wondering is if it makes sense to have a...

Good Morning! I have not had a good chance to go through all of the code: I don't see anywhere that you call attachInterruptVector, but if you did, I would probably make sure all of my interrupt vectors had...

Good Morning all: Sounds like we have things coming along well here, to understand some about partitions and getting the volume label. :D But our test has not handled SD Cards with multiple partitions ;) For...

My exfat was failing as well, will look tomorrow unless someone beats me to it.

Have Fat16 working I believe at least for USB, have not tried with SD yet... // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and USB mass storage...

Hi @defragster and others... Thought I would show so more stuff that is not working :D // VolumeName.ino // An example of how to retrieve Fat32 and ExFat volume names using SdFat. // Works with SD cards and...

Note: I have been playing some with adding Fat16 maybe stuff and not finding the VolID... Some output currentlly: Waiting up to 5 seconds for USB drive Initialize USB drive...FsVolume::begin(20001b28)...

@all - Wondering in my above Partition table dump you see: msc1 Partition Table part,boot,bgnCHS,type,endCHS,start,length 1,0,0x4,0x1,0x4,0xB,0xFE,0xC2,0xFF,2048,8192000...

Hi @mjs513, I slightly hacked up your sketch, by moving a lot of it from setup() to loop() with a wait at the end of loop() for user to enter character. That way you can hopefully rerun. I also have it wait up...

@all... I am winding my way through the different layers and trying to figure out how to get USB Drive partitions to work. It might be nice to be able to do something like: today the VojumeName.ino does: if...

Glad you have some building and ready to play :D Did not get as much done yesterday, but will now try to see if I can get this MSC volume code and the like to read from all 3 partitions on my USB stick...

Take this with a grain of salt, but what I am planning to look at includes: In the sketches we have: msController msDrive1(myusb); Each one of these is for a physical USB drive, I believe it claims the device at...

Note: the get volume label code was not working for me as probably timing. My USB is connected through HUB and so takes a bit of time before all of the stuff is setup. So I have it check to make sure the drive is...

As far as I know it should work. The code just figures out which Serial port gets passed in to dxlInit: void dxlInit(long baud, HardwareSerial* pserial, int direction_pin, int tx_pin, int rx_pin ) { As the AX12...

Sort of an old thread to resurrect. But by PMs been asked if I could convert the board to Altium... Not sure if you would gain much. The whole design: I did try to export the board layout to Eagle file in...

Mtp serial still need the usb_desc.h stuff copied in

Thanks @wwatson - tried the sketch, but the two drives I tried were exfat... Will try again. Thanks for the hints: I verified that in my debug outputs, the first calls msReadBlocks is in the this case is from a...

@wwatson @mjs513 and @all - my eyes are mind is not seeing some things... For example: I fixed my USB thumb drive partitions to not use extended partition... I turned off USBHost_t36 debug (in that header) but...

@... I have been playing around and understanding some more with the MSC stuff and partitions... If you run the sketch SdInfoUSB it will print the partition table stuff (Block 0). My output is way too much to...

I tried formatting a thumb drive to have 3 partitions, A Fat32 primary An extended partition table With a secondary partition with Fat16 and a secondary partition with Fat32 And my MTP with MSC, goes BOOM.....

@mjs513 an d @wwatson I will try playing some with that. Have anyone tried doing some of the same type tests on thumb drives or the like? I think I will try to partition a test thumb drive and see what might work......

@mjs513 - Not a problem... Hope not too much snow! Here it is raining and upper 40s... Will play more, but may want to switch gears to see about partitions on USB disks, which is probably more interesting. Also...

For the fun of it, I thought I would see if I could get it to read an ExFat one... I think this one sort of works for it. Probably a real hack, but... When you are dumping out the top partition table, I keep the...

@defragster - Looks great. Interesting with Low memory availability messages, I assume they most use a percentage... As 4K free on an LC would be 50% ;) I see the changes were pulled in
