Fixed this now works for USB devices:

msc1 Partition Table
part,boot,bgnCHS[3],type,endCHS[3],start,length
exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000
FAT32:...

Out of curiosity I did add a print directory (LS) for the fat just to see if it work:

msc1 Partition Table
part,boot,bgnCHS[3],type,endCHS[3],start,length
exFAT:...

@KurtE
Got it partially working

msc1 Partition Table
part,boot,bgnCHS[3],type,endCHS[3],start,length
exFAT: 1,0,0x20,0x21,0x0,0x7,0xFE,0xFF,0xFF,2048,204800000
FAT32:...

@KurtE - @all

Finished my diversions this morning and guess I am going to start playing with partitions again. This stuff is giving me a headache to be honest - a lot of pieces to the puzzle.
...

Thanks Kurt - right now by brain is mush working on multiple things at a time :) Need a break before getting back into it.

Question:
To set up a volume say for an exFat partion I do a:
expartVol.begin(sd.card(), true, 1);

for an SD Card. Now, if I am using a usb drive (non sd). What do I do for a blockdevice...

Try pulling from Paul's repository for USBHost_t36 - I switched over to that for testing. Just looked looks like its like it should be the same though.

@defragster
Maybe its using an outdated USBHost_t36? or maybe try it from Arduino IDE :


Using library UsbMscFat-main at version 1.0.0 in folder:...

@defragster
I am assuming that those libraries in T:\tCode\libraries\ are some linked to the libaries in T:\arduino-1.8.13_t54\hardware\teensy\avr\libraries?

Ok cool was just looking at this now - so now don't have to. Do have to so some testing with the changes though in MTP and standalone :)

Ok here is one for you all

Out of curiosity I just downloaded it again but used Firefox. No issues with defender and my Norton pop-up came up and said it was a safe file. I added that rule a...

Not 100% sure. In post #435 @wwatson mentioned that the only thing you need in your libraries folder is: https://github.com/wwatson4506/UsbMscFat..

I did delete all the old MSC files - uSDFS,...

@wwatson - @KurtE - @defragster
Just ran your test sketch in post #433 and it worked like a charm. Recognized exFATs and FAT32 to get the volume name.

Have to go find my hub to test with again...

@defragster
Nope the those lines are in my version. Note - never created a build.local.txt file that I remember but then who knows may have did that a long time ago and just got use to it being...

@defraster
Don't remember ever having a boards.local.txt file there before. Anyway that is in there now for all Teensy's not the the T4.1

Item #1: teensy.exe is staying around 0% with periodic jumps to 0.1%. Java Platform SE Binary goes between 0% and 0.7%

Item #2: see post #10

A couple things for Beta8:
1. ...

Did notice the new memory usage in both Verbose and non-verbose. In verbose I am seeing this additional info:

Linking everything together......

@Paul
Just downloaded Beta7 and pretty much saw what @defragster saw in post #4. I did one additional step. Before telling defender to Keep file I clicked on REPORT THIS FILE AS SAFE:

Once...

@KurtE
Funny when I put in my SSD it showed the contents of the first partition as I expected.

I was rummaging around mscUSB but I didn't see any linkages back to SDFat for the Volume commands...

Not yet. Not sure how much of the vol and partition stuff is exposed in msc. Haven’t looked at yet

@KurtE
Been searching the code and the help system as well but to no avail. Nothing I have found seems to return the volume name. Think @wwatson mentioned in an earlier post that he was doing...

@KurtE - @wwatson
Decided to play around with the BufferedPrint example to see what it takes to write and read files from the partitions. Did manage to create 3 partitions that I can test with;
...

@KurtE
Sorry for the delay in responding. Was busy playing and watching more snow fall :(

Any tried to modify formatter but haven't broken the code on that one and wound up messing up my...

Taxes - yep - already did mine.

Anyway get the volume directory was relative easy.

SdFat version: 2.0.5-beta.1
Assuming an SDIO interface.

type any character to start
init time: 22 ms

@wwatson
Thanks for the changes will play more with it tomorrow. May try to do a list files but intent really was to see if and how to get access via sdfat. But the use of sd.card was the key

Hopefully no more issues. Hope that list is getting shorter but have a feeling it’s getting longer.

Should have mentioned. Running Ubuntu 20.04.02LTS 64 bit on the PI4. Don't really have any other Linux systems. Probably can did out a RPI3 and see what I have on it and give it a try if you think...

Ok - just tried it on a RPI4 and its now working.

Guess the order matters - 00 versus 49. Forgot to document but think you added an extra rule as well to the file.

First don't despair. I have had many UBLOX modules working with the Teensy (most 3.2 and up) and never had a problem. The first thing I usually do is use a Hardware Serial Port as opposed to using...

Thanks - the dummy that I am. So with that ran it but I created 4 volumes 3 are FAT32 and 1 is exFAT. This is running the SDInfo without Partition info set up:

SdFat version: 2.0.5-beta.1...

Morning @KurtE

Was trying to implement your changes and found you already implement them in the repository example so.... Using just 1 MSC object ran into a couple of problems with some devices:...

RE Partitions: SDFat only supports single partition. See https://github.com/greiman/SdFat-beta/issues/69

Have fun. Make sure you use @KurtE's branch. https://github.com/KurtE/MTP_t4/tree/MEM_send_object_large

@KurtE
Was poking around SDFat and not 100% sure it directly supports multiple partitions. Why, Blockdevice* dev I believe has to point to the SDCard but doesn't appear we have access to that. Bill...

Just including this for reference: https://forum.pjrc.com/threads/55821-USBHost_t36-USB-Mass-Storage-Driver-Experiments?p=271015&viewfull=1#post271015 on using partitions.

@KurtE - @wwatson

Not sure where to post this (kind of crosses - Integration Thread)

Anyway not sure how this would work but SDFat does have a FatPartition Class that looks like it would allow...

@KurtE

You just knew I had to download your changes to test MTP with MSC (UsbMscFat).

Anyway hooked up my SSD and low and behold it showed up in MTP and was able to do several things:
1. Copy...

Morning again - can't sleep so catching up

As for restarting. I did close and reopen the IDE but didn't disconnect the Teensy which was probably the issue - didn't even cross my mind to unplug...

Morning @KurtE

Sorry I didn't get to this yesterday - still recovering a bit and had another distraction.



I agree with 100%. For the things that you described those are the things that...

This is the latest version that I am working with and should give you everything you need: https://github.com/wwatson4506/Ra8876LiteTeensy, for the RA8876

@wwatson
Just downloaded UsbMscFat and so far examples working a couple different devices I tried - 32 thumb drive, SD Card in adapter and a SSD drive. Here some info from one of the examples:
...

For comparison in the sketch I was using I have slightly different timing for messages: heartbeat = 1Hz (think this interval is fixed), AHRS (roll, pitch, yaw, rotation rates) every 100ms, GPS...

@KurtE

My suggestion would be that if it is a specific library related issue it should be on the appropriate thread. For instance if LittleFS is formatting correctly or not recognizing a flash...

ok - as shown didn;t really work for me - but then I really have no idea with Linux so just used gedit to create the file. Restarted and it now works with serial monitor as you said.

Maybe Paul...

@KurtE

getting an error when I try to execute your first line:

ubuntu@ubuntu:~$ /etc/udev/rules.d$ cat 99-hidraw-permissions.rules
bash: /etc/udev/rules.d$: No such file or directory

...

@KurtE
Not to the serial monitor.

Either output to textEditor or directly into the IDE window - depending which I had selected (active). But I did get output even when I had keyboard printing.
...

Can confirm that the app works with 20.04.02LTS.

Tried the same sketch as @KurtE and when I selected Serial+Keyboard... did get out on the Serial monitor.

Of course
But just remembered the password when I was setting up with the new version :) Getting the updates now.

Installing fresh Ubuntu on my PI now to see what happens. Using 20.04 LTS instead. Looked like 20.10 support ends april 2021. Using the Raspberry Pi imager then will do the updates.

And before...

Well using the Arduino IDE I just compiled your sketch with no errors or warnings.

I am assuming you have to select Teensy 4 in platformIO so only other thing is are you sure you are...
