    @All,

    Sorry I have not responded for the last few days. I lost the computer to a power supply flame out. Fortunately I had most of my data backed up but not all of it. I spent most of this long weekend setting up a laptop and another desktop just in case this happens again. I think I am finally caught up with you guys

    Got the T$ Saturday and have started to work with it today. I grabbed all of the documentation for the 1052 and 1062. The one thing I have to do is understand how the pinout diagram works.
    I guess starting with the 1062 ref. manual.

    I want to get back to working MSC as soon as I can and see if I can improve the transfer speed.

    Awesome work on partitions. I do have minimal POSIX style file system working on my other T36 setup and want to port it over to the T$.

    Hi @wwatson - Sorry to hear about your computer...

    One of these days I should probably do a better backup of my computers.... But...

    Yep pin out is up on the T4 thread: https://forum.pjrc.com/threads/54711...irst-Beta-Test
    Posting #3...

    There is new rev of hardware manual... Which you can get using download, but must create an account.

    I also now tried it where I redid the 2 partition disk on Ubuntu 18.04 using gparted and had it format as Fat32... And test app still worked.
    Wow - this thread went quiet for dozens of hours! I found one of my Star-Tech and the Apricorn USB3 'minimal' cable USB to Sata adapters …

    My ZIP is dated 5/26 and I see I have this noted version #? :: Using library uSDFS at version 1.1.1 in folder: T:\tCode\libraries\uSDFS
    Went to plug one into HUB to test and getting yelled at for this:
    Code:
    T:\TEMP\arduino_build_logger_RawWriteHub.ino\libraries\uSDFS\ff.c.o: In function `check_GPT_disk':
    T:\tCode\libraries\uSDFS\src/ff.c:3257: undefined reference to `VolToPart'
    It needs @mjs513's p#272 :: PARTITION VolToPart[] = {{0,0}, {1,0}, {2,0}, {2,1}, {2,2}}; /* Volume - Partition resolution table */

    Using the Apricorn on my Plextor SSD 13 MB/s and not even a HUGE buffsize at 16K … 64KB of RAM:
    Code:
    Test logger_RawWrite
    BUFFSIZE :16384
    Dev Type :2:/
    File System FS_EXFAT
    Free Disk Size -1 clusters
    Cluster Size 256 sectors
    Sector Size 512 bytes
    
    Change drive
    A_00001.dat
    stat FR_OK 0
     opened FR_OK 0
    
    ................................................................
    .................................... (5008995 - 13.083662 MB/s)
     (open: 9033 us; close: 9000 us; write: min,max: 4940 4945 us)
    That speed with:
    Code:
    #define MXFN 100 // maximal number of files //was 100
    #define MXRC 1000 // number of records in file // was 1000
    And it needs this to run through a HUB:
    Code:
    #include <USBHost_t36.h>
    extern USBHost myusb;
    USBHub hub1(myusb);
    USBHub hub2(myusb);
    Funny I accidentally type 18 instead of 16 for BUFFSIZE and it went slower! and with 8K buffsize it only did 8 MB/sec

    Of course this is bad testing for SSD drives - the more spastic writes the more wear on the FLASH - and without OS TRIM support the free space isn't cleared in advance on delete - that's why I went with the Seagate HDD for testing.

    Really need to get to a read test ….

    @All - Sorry I have been offline so long.

    I have been doing alot of research with the EHCI USB controller and mass storage devices. I think I may found out why USB thumb drives are slower than regular hard drives or ssd drives. Most hard drives support onboard write caching. The thumb drives I have and tested did not. From what I could find on the Internet they don't. You can support write caching through software but it is not recommened because if there was power loss you could lose data. You can turn write caching on/off in most OS's.

    As a test, I used the 'hdparm' command in Linux to turn the devices onboard caching off and on.

    With caching turned on:
    Code:
    Test logger_RawWrite
    uSDFS_VER:30_MAY_19_15_00
    BUFFSIZE (bytes):32768
    Dev Type :2:/
    File System FS_FAT32
    Free Disk Size 7613710 clusters
    Cluster Size 64 sectors
    Sector Size 512 bytes
    
    Change drive
    A_00001.dat
    stat FR_OK 0
     opened FR_OK 0
    
     (24998 - 1.310825 MB/s)
     (open: 31033 us; close: 18000 us; write: min,max: 6976 6976 us)
    
    unmount FR_OK
    With caching turned off:
    Code:
    Test logger_RawWrite
    uSDFS_VER:30_MAY_19_15_00
    BUFFSIZE (bytes):32768
    Dev Type :2:/
    File System FS_FAT32
    Free Disk Size 7613710 clusters
    Cluster Size 64 sectors
    Sector Size 512 bytes
    
    Change drive
    A_00001.dat
    stat FR_OK 0
     opened FR_OK 0
    
     (104998 - 0.312082 MB/s)
     (open: 65030 us; close: 75000 us; write: min,max: 29976 29976 us)
    
    unmount FR_OK
    Different drives have different cache sizes so the results varied between the drives I tested.

    It shows a fairly substantial difference. So I guess maybe the best way to increase the write speeds especially for thumb drives is to do write caching through software.
    I have not done this before so it will be a new learning experience for me (Any help appreciated). Wondering if the 'Circular Buffer' library would be usable or practical in this application.

    Anyway, I am getting the same speed results with the T36 and T4.

    Wow - that looks SLOW in both cases? I've gone to " BUFFSIZE :16384 " and it seems to be capable and good there - It is slower at BUFFSIZE 8K { Max 8.139 MB/s } and not much better at 30K { Max 13.5 MB/s } - and I still get errors at 32K?


    I put these numbers on the T4 - I did a 64GB usb3.1 ADATA flash drive - but closed post before writing:
    > Tested USB HOST to SSD and HDD - both hitting 12.8 to 13 MB/sec disk writes with 64 KB buffer.

    Oh yeah - the numbers on FLASH were as high at 4-5 MB/sec - and then some batches were suffering from DRIVE Overhead where the next dot sat and sat. Doing a repro I am seeing 3.5 to 6.9 MB/sec:
    Test logger_RawWrite_FS // Edited the SKETCH to put out the _FS name in this case

    On SD Flash Cards 'Fast Logging' the recommendation has been pre-allocated files? Then truncating on close? - I've not looked at the mechanics of that ...

    Doing that up front - when max file size is known would get the FAT updates and Dir entry overhead out of the way - and might inspire the FLASH drive to clear and allocate the needed pages in advance - so file create/open could take 'some time' - but would run at best speed after that.

    How many files can currently be opened at once? A test of 'PreAlloc' might be faster and less dangerous than parsing writes and dedicating buffers for multiple files - if just a single file then the cache would be just writing in proper device size blocks 512 bytes or larger?

    I keep meaning to read the DOC thingy - is there a way to get the VOLUME NAME? Would be nice to show that to record the device at hand. Also a READ example I keep hoping to get to …

    Here is HIGH and LOW of 128 MB cache Seagate 2.5 in that Orico Hub/Drive box - runs at same speed at SSD:

    Okay I opened the DOC HTML - making so many test drives I've been putting Drive and size info in the LABEL so I know which BOX is Which. Here is my Seagate Barracude 500 GB drive:

    in ...\libraries\uSDFS\examples\logger_RawWrite_FS\lo gger_RawWrite_FS.ino
    Code:
      void init(void)
      {
        Serial.println("Using uSDFS");
        Serial.print("uSDFS_VER:"); Serial.println(uSDFS_VER);
    //...
        /* Get volume label of the default drive */
        char Vstr[24];
        uint32_t SN;
        f_getlabel(Dev, Vstr, &SN);
        Serial.printf("Volume Label: ");
        Serial.printf(Vstr);
        Serial.printf("  Ser#: ");
        Serial.println(SN);
    


    Had to edit library file : ..\uSDFS\src\ffconf.h
    Code:
    #define FF_USE_LABEL	1
    /* This option switches volume label functions, f_getlabel() and f_setlabel().
    /  (0:Disable or 1:Enable) */
    Code:

    Yeah, it does seem slow. I am going to use 'RawWrite_FS' and retest everything. It seems the larger the file to a point the lager the MBs is. I think this has to do with the sketch in that the calculations for speed are based on the number of 32 bit writes including file open and close times. And if I am right the file size is based on the buffer size.

    I keep meaning to read the DOC thingy - is there a way to get the VOLUME NAME? Would be nice to show that to record the device at hand. Also a READ example I keep hoping to get to …
    Yes there is. I was using that in my initial demo example program which with all the recent changes will not work any more. I have to find it and rewrite it. You can get the volume label and the serial number.

    I have to go out for a while but when I get back I will get the code and post it.

    I was also getting 13 to 14 MBs with some of my drives. I think that was on my Seagate Barracuda 500GB drive.

    EDIT:
    Good deal. Guess you found it.

    @wwatson:
    >> I got the VOLUME label displayed p#283

    >> the file size and test is a combo of "4 byte BUFFSIZE[ ## ]" and:
    Code:
    #define MXFN 10 // maximal number of files //was 100
    #define MXRC 1000 // number of records in file // was 1000
    This says 10 files of 100 records - and indeed EACH record is of size BUFFSIZE.

    I just dropped to MXRC of 10 and with only 10 records per file the max number with BUFFSIZE 16K :: 11.109303 MB/s

    So shorter tests are faster to execute and get MOST of the speed

    Is one possibility
    my reasoning was, that sd_config.h would be edited to say which interface one is using (spi,sdio,usb) where one could also have 2 or more spi devices
    Also sd_config should be always checked as it has spi port definitions.

    now, can weak be also used for structures?

    if the location is 'too hidden' I could also move 'sd_config' into uSDFS.h which is to be used in main sketch

    There probably is a good answer - I've only hacked the sketches following into sources as needed- not looked at the bigger picture. One possible way would be to have a default VOL* to a generally good list and allow a sketch update in setup() - but I don't know which parts of this are compile versus runtime to get the needed parts included. Having multiple devices seems important for some uses

    I realized that having the VolToPart in sd_config.h could result in multiple declaration, so I moved it to uSDFS.h, which is only called by main thread.
    This way it can be changed without need to recompile library (is declared external in ff.h)
    if you wanted to use your own VolToPart you then in your sketch simply do something like

    Code:
    	#define MY_VOL_TO_PART
            #include "uSDFS.h"
    	PARTITION VolToPart[] = {{0, 0}, //{ physical drive number, Partition: 0:Auto detect, 1-4:Forced partition)} 
    			        {1,0}, 
    	   	                {2 0}, 
    				{2, 1}, 
    				{2, 2}
    				 }; /* Volume - Partition resolution table */
    or
    Code:
    	#define MY_VOL_TO_PART
            #include "uSDFS.h"
    	#include "sd_config.h"
    	PARTITION VolToPart[] = {{DEV_SPI, 0}, //{ physical drive number, Partition: 0:Auto detect, 1-4:Forced partition)} 
    				 {DEV_SDHC,0}, 
    				 {DEV_USB, 0}, 
    				 {DEV_USB, 1}, 
    				 {DEV_USB, 2}
    				 }; /* Volume - Partition resolution table */

    That certainly works to make it usable!

    I read the docs there is : 'The f_expand function prepares or allocates a contiguous data area to the file.'
    Cleaner to use than an l_seek it seems - but the file has to be 0 length to start - so if it exists would require this first: 'f_truncate - Truncate size'

    I went through and got rid of ALL warnings on my copy - it still works. Did two file pull requests.

    Also did a clone to look at doing a logger_RawRead version … will see if I get back to it.

    Another edit to ffconf.h :: #define FF_USE_EXPAND 1 /* This option switches f_expand function. (0isable or 1:Enable) */

    And this worked:
    Code:
          if ((rc = f_open(&fil, filename, FA_WRITE | FA_CREATE_ALWAYS))) die("open", rc);
        }
        rc = f_truncate( &fil );
        if (rc != FR_OK) die("truncate", rc);
        rc = f_expand( &fil, 4*BUFFSIZE*MXRC, 1);
        if (rc != FR_OK) die("expand", rc);
    
    Hard Disk ran at same speed - though more consistent, ran with "R" test files two at 13.0395, two at 13.01, the other six 13.0420
    64GB aData Flash drive made it to 13 MB/s up from 6.9 Max posted above - but the first was SLOW and it still took HITS on some dots - and some HUGE open times.
    2nd Run gave with same file names: 2.9, 4.3, (4*)6.6, 7, 8.4, (2*)12.9

    And before this was probably slower and less consistent an 8 GB SDHC card - though turning above code off on same files is getting the same speed running again - except I got one 5.05, a 5.15 and a low of 4.2 MB/s:

    I thought it would be interesting to see what the read/write speeds are with reading/writing sectors directly through MSC with t4.

    These are the results with various buffer sizes on HD's:
    Code:
    Direct sector read/Write speed test
    (Destroys any data on the drive!)
    
    Write speed is 3000 2.730667 MB/s for 8192 bytes
    Read speed is 2992 2.737968 MB/s for 8192 bytes
    
    Write speed is 3000 5.461333 MB/s for 16384 bytes
    Read speed is 2992 5.475936 MB/s for 16384 bytes
    
    Write speed is 4000 8.192000 MB/s for 32768 bytes
    Read speed is 2992 10.951872 MB/s for 32768 bytes
    
    Write speed is 5000 13.107200 MB/s for 65536 bytes
    Read speed is 3992 16.416834 MB/s for 65536 bytes
    
    Write speed is 6000 16.384001 MB/s for 98304 bytes
    Read speed is 4992 19.692308 MB/s for 98304 bytes
    These are the results with various buffer sizes on thumb drives:
    Code:
    Write speed is 3000 2.730667 MB/s for 8192 bytes
    Read speed is 3992 2.052104 MB/s for 8192 bytes
    
    Write speed is 3000 5.461333 MB/s for 16384 bytes
    Read speed is 2992 5.475936 MB/s for 16384 bytes
    
    Write speed is 5000 6.553600 MB/s for 32768 bytes
    Read speed is 2992 10.951872 MB/s for 32768 bytes
    
    Write speed is 8000 8.192000 MB/s for 65536 bytes
    Read speed is 4992 13.128205 MB/s for 65536 bytes
    
    Write speed is 11000 8.936728 MB/s for 98304 bytes
    Read speed is 5992 16.405874 MB/s for 98304 bytes
    The results of the sector writes are about 1 MBs faster than the uSDFS file writes. (On my drives).
    I have not figured out why 8192 byte and 16384 byte buffer read/writes are almost the same speed yet.
    Noticed that the thumb drive write speed does not change after a buffer size of 65536.

    Now to reformat all the drives I tested on and do some file read speed testing with uSDFS.

    Nice to see a couple bigger numbers showing the USB has a bit more headroom at 16 and 19 MB/sec. I got some new Flash drives and SDHC cards - still unopened. And the new TD beta took me away from thinking about my RawRead sample a bit ...

    Here is the result of some more tests I ran on the T4 and MSC.

    Code:

    msController CallbackOut (static)
    transfer->qtd.token = 0
    msController dataOut (static)31

    The out transfers are taking about 1ms to complete. The multi sector writes are limited to 16 sectors by FatFs. (8192 / 512 = 16). I have not found why yet. It might possibly have to do with cluster sizes. So no matter how large the buffer is the maximum number of bytes transfered in one transfer through FatFs is gong to be 8192 byte or 16 512 byte sectors.

    Code:
    msController CallbackIn (static)
    transfer->qtd.token = 0
    msController dataIn (static): 512
    54 45 45 4E 53 59 46 4C 41 53 48 08 00 00 C7 75 C8 4E C8 4E 00 00 C7 75 C8 4E 00 00 00 00 00 00

    In transfers appear to be the same. About 1ms.

    @defragster - Been looking to find out why the out transfers seem to be stalling at times. I see this 'transfer->qtd.token = 1' which indicates that EHCI has recieved a NAK from the device because it does not have room in the write cache for any more data until it emptys and is in a PING state asking if the device is ready to accept more data. (EHCI reference manual - page 44, and pages 88-89). Not sure if this is the cause but it happens more with thumb drives than hard drives. It could also be from a stalled pipe which is handled by EHCI. Just not sure.

    @Paul - Please correct me if I am wrong about the PING state.

    Edit:

    Found one hard drive giving different results:

    may this be connected with the 16384 Byte limit in aueue_Data_Transfer in ehci.cpp?
    (I know you said 8192 but i know FS is sending lager blocks (I recall a transfer of 64*512))

    I am pretty sure it's based on cluster sizes. I 'loggerRawWrite.ino' you display the reported cluster size. I found that it matches the block count sent by FatFs.
    Ehci.cpp breaks it up into 16384 byte chunks sent if it greater than 16384.

    Heading to work now.

    if there is a match, then there is a good answer

    I don't know of I have missed something but I just did a git pull on uSDFS and I ca't seem to compile 'logger_RawWrite.ino' any more without the following errors.

    Error compiling for board Teensy 4-Beta2.
    Did not backup uSDFS before I did the git pull. Any Ideas?
    I had just got the WavFilePlayer.ino working with the T4.

    Can't seem to find the problem.

    Edit: That is WavFilePlayer.ino with uSDFS and MSC.

    ~May 26 is the last I see downloaded ZIP for uSDFS - there was a new Beta after that with the time change from TeensyLoader? I don't see other newer downloads from this thread since then. My last run notes post above is 6/3 … without DOCS it re-zips to 723KB …

    found some issues that where introduced while handling other thread (bat recorder) compilation issues.
    updated github

    @WMXZ - Thanks for the update. That fixed the problem. I really like using this library. Versatile and easy to use
