TMS320F28379D: Unable to program the DSP with usb_flash_programmer

Sebastien DESHAYES

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE, UNIFLASH

Tool/software:

Hello,

I contact you about an issue we have regarding the software update of your DSP (part number TMS320F28379DPTPS) using USB interface.

When using the command « usb_flash_programmer.exe F2837xD_usb_flash_kernels_cpu01_dual.dat MISTAAMP_BswTest.dat F2837xD_usb_flash_kernels_cpu02_ram.dat MISTAAMP_BswTest.dat », we get an error and the process stops.

Our problem could be linked with the issue https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1230406/tmdscncd28379d-usb-flash-programmer-does-not-work-with-larger-files

Could you help us regarding our issue ?

This functionality is really important and needed for our product.

Our configuration:

CCS Version: 10.3.0.00007

Hello

it seems we have exactly the same problem as Brent Williams in this post (long thread without a solution at the end : switch to chat mode). we also already tried the very small led_ex1_blinky example...

Hi,

What version of C2000ware are you using to attempt the USB Flash Program load?

Thanks and regards,

Charles

Hi,

we tried V3_04_00_00, we also tried V5_04_00_00, same problem.

Was Texas Instruments able to help Brent Williams perform a firmware update using the native bootloader ?

reminder:

The update operation involves the "usb_flash_programmer", but also the "usb_flash_kernel".

Hi Christophe,

The conclusion to the Brent Williams USB Flash Programmer thread was that the USB device he was using needed to be changed

One of our experts has listed the steps in this thread for success with this issue.

Thanks and regards,

Charles

Hi Charles,
The issue seems to be something else than what is described in the USB Flash Programmer thread .
Apparently Christophe is able to reproduce it on the TI Delfino F28379D controlCARD:
-USB boot + USB_flash_programmer (from C2000Ware 5.02) to burn blinky_dc_cpu1 works
-USB boot + USB_flash_programmer (from C2000Ware 5.02) to burn larger file does not works.

Do you have a TI Delfino F28379D controlCARD to repoduce it?

Thanks in advance,

Anthony

Hi,

If you have a I Delfino F28379D controlCARD, we can provide our firmware binary in order to help to reproduce the problem.

Thanks in advance,

We try to update the firmware of our Delfino F28379D controlCARD using TI tools usb_flash_programmer and c from C200Ware v5.02, and our firmware was recompiled using C200Ware v5.02.

usb_flash_programmer FAILS, error 0x79 (timeout) after 14336 bytes, no error explanation.

We then tried to debug TI usb_flash_kernel program

The usb_flash_kernel FAILS and do not provide error information... it only stops the DSP : asm(ESTOP0)

The error happens inside CopyData function, after 7 block transfers, in the "program non aligned block", after Fapi_doVerify call (line 213).

It seems there is a problem between TI usb_flash_programmer and TI usb_flash_programmer programs.

Do you have an explanation / history for this problem / situation ?

Thanks in advance.

When we flash the demo firmware blinky_dc with the kernel and usb_flash_programmer, it works.

Best regards

0 guerit christophe 6 months ago in reply to guerit christophe

Prodigy 200 points

Can you tell us how to find the reason why the usb_flash_kernel fails when updating our firmware? A tolerance problem on the size (our firmware is bigger than TI blinky_dc firmware)? Alignment constraints ? We can provide our firmware binary, our linker script, .. what else ?

Best regards

My collegue S. Tarik was working on the same subject, he as opened a post 2 months ago concerning the same subject (cannot flash firmware : error) , without any answer from ti, except finally a question: " Do you still require support?"...

Hi Christophe,

guerit christophe said:

Have you checked the .dat file generated by the linker to understand if alignement is ok?
Are you using ALIGN(8) as default for this linker command file?

Prodigy 200 points

Hi Anber,

Yes we did check alignment a short time after our post 2 days ago.

He's our link cmd file.

Hi,

And i propose to send you the firmware binary file, if you want to investigate.

Best Regards

We are available to provide you with further information for investigation,

do you need additional information ?

We have no news concerning this thread,

We followed the firmware update via USB procedure.

The usb_flash_kernel fails when updating our firmware and stops (no error reported) ? What could be the possible reasons ?

We provided the linker script (memory/flash mappings) and we can provide the .dat file of the firmware.

Any advice ?

Best regards,

CGuerit

Hi,

Apologies for the delay in response, the expert is currently out of office.

Question, what is the size of the current file in bytes compared to the size of the flash memory you wish to program?

In the meanwhile, yes can you provide the further information through the messages to me on the file itself?

Thanks and regards,

Charles

Hi Charles,

Reminder: our microcontroller is a TMS320F28379DPTPS, and flash programming works perfectly using JTAG (CCS or uniflash)

CCS produces a ".out" file : .out 765K and a ".hex" file (for uniflash) : 247K

HEX2000 converts the ".out" file into a ".dat" file : 106K

We use the ".dat" for usb flash programmer.

Note : compilation is in "debug mode".

Flash programming stops (timeout) after ~13K (usb flash programmer message)

I join one more time the linker script to this message, I propose to send you the ".dat" file

Best regards

Christophe

Hi Christophe

Request you to provide the .dat files also. I will have to reproduce this issue and figure out the cause.

Did you check till what address if the flash getting programmed by the kernel?

Hi Siddharth,

Please find attached our DSP firmware, in ".dat" format. You already have the linker script.

The usb flash kernel stops without sending an error code to the usb flash programmer.

Flash programming stops (timeout) after ~13K (usb flash programmer message)

Hi Siddharth,

Were you able to retrieve the ".dat" file that I sent you on Wednesday?

Yes, I got the .dat file that you had shared.

I am trying to reproduce the issue on a Control Card but running into some other issue.
The usb flash programmer is unable to detect the device connected.

Will keep you posted on my findings.

I hope you have a TI Delfino F28379D controlCARD (and not the LAUNCHXL).

May be this can help you:

=> Did you install the driver for USB bootloader ?

=> Did you write 0x0C5A to the boot mode select address (0xD00) with the debugger ?

Best Regards,

Christophe

I had to manually install the driver to make it recognized as "F28x7x_USB_Boot_Loader" instead of "Stellaris Device Firmware Upgrade".

After this, I was able to run the usb flash programmer utility.

I was able to recreate the issue that you are seeing. Looks like there are sections in the file which are not aligned on 8 byte boundary. The Fapi_Verify function fails for address 0xBE02A.

request you to share the .out and the .map file that is generated .

You can also see if using the "fill = 0xFFFF" option in the linker command file for the FLASHN1 section solves this issue.

Best Regards

Siddharth

Hi Christophe,

Pls check if the following symbols are aligned on 8 bytes

SW_IDENTIFICATION
ANALOG_TRIM

Best Regards

Hi Siddarth,

Thanks for the advice, the GROUP was declared align(8), i added align(8) for SW_IDENTIFICATION and ANALOG_TRIM elements.

Using the "usb flashing procedure" (jtag 0xD00 configuration / reset / resume) the usb flash programmer now fails while flashing the application on the second cpu (see below)

Important: flash programming works using jtag and fails only for usb).

I join the modified linker script, map file, application file, and the 2 kernels.

Any ideas ?

Best Regards
