USBHost_t36 USB Mass Storage Driver Experiments

**wwatson** · 04-19-2019, 02:54 AM

Mass Storage Controller (MSC) library for use with Teensy 3.6

This is a project I have been working off and on for two years.
It is a very minimal working USB host mass storage driver for use with the Teensy 3.6 USB host port.
At this time there is very little error checking done. (Not completely processing error and sense codes yet).
Definitely work in progress.

The test program is a modified version of "uSDFS_test.ino" from WMXZ's uSDFS library which can be
found here

Code:

https://github.com/WMXZ-EU/uSDFS

. That library also uses ELM-ChaN FatFs library.

Tested with Arduino version 1.8.9 and Teensyduino version 1.46b10.
I do not have or use Windows so MSC has not been tested with that operating system. It should work.
It is working with Linux Ubuntu 18.04 and Mate Desktop 1.12.1.

Libraries used:
* USBHost_t36 PJRC USB Host library.
* uSDFS WMXZ Teensy uSDFS library modified for use with msc.
* MSC Mass Storage Controller, USB Flash drives and USB Hard drives. (see below)

Installation:
Install MSC and uSDFS into "~/Arduino/libraries" folder.
No modifications to USBHost_t36 are needed at this time.
In the MSC folder you will find 4 files in the "MSC/uSDFS_Files_Copied_To_uSDFS" folder that
need to be copied to the "~/Arduino/libraries/uSDFS/src" folder.
They are:
diskio.h
diskio.c
ffconf.h
uSDconfig.h
I would back these files up before replacing them.

I modified uSDconfig.h to add Mass Storage drive "0:/". Drive "1:/" is now the native SDHC drive.
How to change the drive identifiers is also documented in this same file.
A drive activity LED is setup on pin 24 in diskio.c for both drives on my T36.
if needed change the define to use another pin.

Kingston, Sandisk and PNY flash drives that I have used all seem to work ok. The PNY flash drive is
really slow to come up. It takes a few seconds. Kind of like the hard drives do.

I have been using a IDE/SATA to USB adapter from StarTech.com to test the hard drives.
Tested several USB Hard Drives, Seagate, Hitachi, Western Digital, and others along with an older IDE drive.
They all take several seconds to come up but are faster than the flash drives.

Here is some output from the test program.

Hard Drive:
Drive "0:/" Mass Storage.

I have seen talk of mass storage on Teensy recently on the forum.
I hope others with better programming skills than mine can use this code as a starting point
for development and testing.
I am also curious if and how other drives work with this driver and the T36.
Lot's left to do if people are interested.

**KurtE** · 04-19-2019, 03:17 AM

Sounds great

**defragster** · 04-19-2019, 06:00 AM

Looking forward to giving it a try.

Can you supply a link to the needed library :: "MSC Mass Storage Controller"

**wwatson** · 04-19-2019, 12:24 PM

@defragster and others the attached zip file "MSC.zip" contains the MSC folder that is copied to your Arduino sketch folder. In my case that is "Arduino/libraries".
The file "msc.h" contains the class definition of msController which also includes "USBHost_t36.h". The only other libraries needed are USBHost_t36 and uSDFS.
I did it this way so that I don't have multiple versions of USBHost_t36 floating around confusing me. There are installation instructions in the readme file in "MSC.zip".
Then it should compile the example ino file in the example folder.

Got to go to work.

**mjs513** · 04-19-2019, 01:00 PM

@wwatson
Great job on getting this working with UHSHost_t36. Just ordered the StarTech adapter to give it a try

**WMXZ** · 04-19-2019, 01:09 PM

Thanks for adding USB-Mass storage to uSDFS (I never had time to do it)
Will definitely try it.

**mjs513** · 04-19-2019, 01:14 PM

@WMXZ - Only thing that needs some work is to get it working on the T$ - next gen Teensy

On a to do list.

**mjs513** · 04-19-2019, 01:56 PM

@WMXZ - then I will leave it to you - just went through it and you are doing things with CTAR table and port mappings that I haven't hit yet on how to do.

@wwatson - just gave it a try on a T3.6 with Cruz memory stick. On the second pass in the loop open the hello file failed:

rc=3 means (I believe) "Device not ready". maybe something with init?

**mjs513** · 04-19-2019, 02:13 PM

Yep. Funny thing is, looks like its suppose to wait for a serial input but I didn't hit any key on the second try. Think I have to look at the sketch again.

**KurtE** · 04-19-2019, 02:19 PM

I will probably try this out as well SOON - but if it is waiting for Serial input on T4, it may be a long wait as we still do not have any USB Serial input support on T4... So if it needs it, you may need to hack up test app to some hardware Serial port.

**mjs513** · 04-19-2019, 03:30 PM

@KurtE
Right now unless the @wmxz updates his library for the T4 it won't work on the T4, only T3.6.

I think I have a pair of StarTech that I just 'put away' … but found a KingWin USB to SATA. Thanks for noting that - I stopped reading after grabbing files failed. Will see if it runs soon.

Thanks @wwatson - I got uSDFS and downloaded MSC.zip - but … opps … did not crack it open after looking for where that lib might be

**wwatson** · 04-20-2019, 03:20 PM

@mjs513

@wwatson - just gave it a try on a T3.6 with Cruz memory stick. On the second pass in the loop open the hello file failed:

I have not run into this error yet with SDHC. Possibly a problem with the SD card, formatting etc...
Do you have another card you can try? or maybe see if you can read or write to it with another device.
I am using a Sandisk 8 gig SD card formatted to fat32. I have used 16 and 32 gig SD cards with success.

The error code used is defined at about line #50 in "diskio.h" and is used in "diskio.c" in this case the disk_write() function.

@defragster

I'm sorry but I don't understand what you mean by "did not crack it open after looking for where that lib might be". My bad.

**defragster** · 04-22-2019, 06:04 AM

Finally got everything unzipped and in place to compile this on a T_3.6 - one embedded in a FrankB Teensy_64.

@wwatson - I meant I started pulling the things down - but not realizing the needed MSC LIB was what was in the zip - not just the sketch - I quit that late night without Cracking open that ZIP file to see the library there.

I'm on IDE 1.8.9 with latest TD 1.46b11 and using the current WIP Bluetooth for T_3.6 and T4 local copy of USBHost:

Multiple libraries were found for "USBHost_t36.h"
Used: T:\tCode\libraries\USBHost_T36
Not used: T:\arduino_1.8.9_146\hardware\teensy\avr\libraries \USBHost_t36

The closest drive at hand was an SSD sitting here - not sure when I last used that - plugged into the KingWin adapter:

@defragster - Sorry it has so long to respond. Doing a few doubles this week. I can't wait for retirement here in a few months. I will have more time to play.
Anyway, I have not ever had a problem with using uSDFS and SDHC (the builtin SD card slot).

I am not sure how to access TD 1.46b11 or if I can for testing. I am using TD 1.46 (Final).

I have installed the new TD 1.46 final and MSC is working with the Mass Storage devices I have available to me.
I also tried MSC with USBHost_t36-WIP2-Bluetooth with success.

The SSD drive is really interesting. No Volume Label and no serial number. But it is obvious that it is performing the disk inquiry function and disk capacity
function (communicating with the drive through MSC). Free space is zero and file open are failing indicating that the file system is either corrupt or non fat
as used by uSDFS. "rc = 13" is a FatFs code for "There is no valid FAT volume".

The ADATA 64 GB, I have no idea why it appears to stall unless it is really slow to come online. I had a PNY 64GB that took well over a minute to come online.
It did the same thing when I plugged it into my Linux machine.

The last 8GB drive is shown "rc = 3" on the SDHC card. This a FatFs error code for "The physical drive cannot work" or drive not ready. Again, a possible format
problem.

I have only used SanDisk SD cards. They seem to be the easiest to use and are very consistent.

The Flash, HD and SD cards are formated as FAT32 and the Boot Flag is set.

Thanks for testing your hardware with MSC. Will be doing a lot more with detecting and handling errors.
Also with hot plugging.

**defragster** · 05-09-2019, 12:34 AM

@wwatson - all good - I'm retired but lots of distractions - the big one being T4 Beta. This just got picked up with update to T4 usable uSDFS … uSDFS on Teensy 4b2

**wwatson** · 05-09-2019, 12:52 PM

@WMXZ @defragster - I have gone through MSC again and found several bugs and omissions. I have and updated version of MSC. See the attachment below.

This is far more stable than the last version. I also added hot plugging. It recognizes disconnection and reconnection and reinitalizes the drive.
I really wish I had more hardware to test with. Mostly flash thumb drive. These to me seem more practical to me then hard drives for file transfer.

In MassStroageDriver.cpp I have made changes to msController::msDoCommand(msCommandBlockWrapper_t *CBW, void *buffer). The main problem there was
the lack of waiting for the in pipe transfer to complete. I have made several other changes to the library including diskio.c where I took out the
WaitMediaReady() call. It is not needed now and was causing problems.

I hope this helps. I am going to setup again using the latest TD1.47B2 and your uSDFS.
I of course can only test with T3.6.

**KurtE** · 05-09-2019, 01:27 PM

@wwatson - Sounds great, will try it. Will be interesting to see how to integrate this back in with the current stuff on uSDFS where some of your previous stuff was brought in... Don't need to copy your files any more...

Maybe we need to edit the diskio.c file on that project to logically add your new additionas, like WaitDriveReady()...

I am guessing that your stuff is not up on Github?

Thanks again
Kurt

**KurtE** · 05-09-2019, 04:12 PM

I tried editing in some of the changes, but maybe made things worse...

I edited the uSDFS file sd_msc.cpp to change: int MSC_disk_status() {return 0;}
to:

Code:

	int MSC_disk_status() 
	{
			int	stat = 0;
			if(!deviceAvailable()) stat = STA_NODISK; // No USB Mass Storage Device Connected
			if(!deviceInitialized()) stat = STA_NOINIT;  // USB Mass Storage Device Un-Initialized
			return stat;
	}

I had a compiler generate an error on deiveAvailable not defined... Which it is MassStorage.h

However the definition in MassStorage.h also generated an error on the like: boolean deviceAvailable(void);

As boolean is not defined. I fixed it in my local copy, by having MassStorage.h include wiring.h which will define boolean.

Very cool wwatson! I updated p#1 this thread to link here for updated source. If you have it on Github I can update with a pointer there ...

**KurtE** · 05-10-2019, 04:07 PM

Not sure if here or the T4 thread is the best place to discuss/debug...

I tried with the current updated library(libraries) and still having issues with the thumb drives...

@WMXZ and @wwatson - First probably need to figure out how/where the USB Host device should be declared. With the example app as part of "this" library you have it explicitly defined as part of the sketch, where as with the uSDFS code it is defined internal to the library... The issue comes up, for example I thought I would try the thumb drive connected to a HUB instead of directly and nothing runs at all as there is no HUB device defined in the uSDFS library. Can define in sketch but it wants reference (or pointer?) to the usb object... Although in practice I don't think it actually uses it...

But back to main thing. Tried with two different thumb drives and I don't think either gets beyond the mount command.

Gets into an endless cycle of transfers... Don't see anything like the next message to do CD...
The newer drive does not work either (I also just tried reformat on windows 10 Fat system... to see if that would change it). Again does not get to the CD... But instead of endless messages it just hangs...

@KurtE, @wwatson, @wmxz

Post over in the T4 thread and pretty much got the same results as @KurtE gets for a Memory Stick, with the exception that I will get a rc=13 at the end. Now, I just tried a SanDisk Cruzer Fit CZ33 32GB USB 2.0 Low-Profile Flash Drive- SDCZ33-032G-B35 circa 2012 and it ran with uSDFS DEMO test sketch, not sure what the differences would be, unless its acting more like a SD Card. Haven't been able to get @wwatsons sketch to compile and run, not sure what I am missing:

Ok - just reformatted my Cruzer 4gb Flash drive for Fat32 and it read the memory and it read it:

EDIT: Both devices I tested with are USB 2 devices. Don't have any new ones to test with. I did have to reformat the cruzer to be a fat32 will try extFat next

EDIT2: The Cruzer worked with exFAT format as well

EDIT3: I put in my really old micro center 1GB drive formatted to FAT32 but this time just hangs as described by @KurtE
