CCS/AM4379: Flashing QSPI with Uniflash

Hi 

I fix the problem of flashing over XDS100v2 emulator.

Not only app file(_ti.bin) should be flash in, but also the bootloader (bootloader_boot_qspi_a9host_debug.bin) 

And also need to take care of the position offset, 0x80000 for app and 0x0 for bootloader.

Now there is still one problem remain....

How can I flash the QSPI Flash with Blackhawk USB560v2 Emulator?

Please help

Hello,

I use Blackhawk USB560v2 Emulator first, but end up with <Error -2083 @ 0x0> when loading Programming FlashWriter.

This is a type of "host connection" error. Basically, the debugger/UniFlash is having issues communicating to the debug probe.

Please see the below article:

Hi Ki,

Thanks for your replying.

Blackhawk USB560v2 Emulator can be detected by Uniflash after I put bh560v2u_io.dll into the directory:

"uniflash_PATH\deskdb\content\TICloudAgent\win\ccs_base\common\uscif"

This file can be found in Uniflah v3.4

But there is another problem I got....

Since no COM port of emulator shows up in Device Manager.

Which COM port should I set for flashing?

I have tried to use the command without selecting COM port, but it is not working...

dslite.bat --mode processors -f C:\ti\EDT1704_3\bootloader_boot_qspi_a9host_debug.bin -d 2 -o 0

Many thanks

Hello,

I've brought this thread to the attention of the device experts who can provide additional guidance.

Thanks

Hi Yi-Lin,

Have you followed the steps outlined in this guide: https://www.blackhawk-dsp.com/support/uniflashv4 ?

Hi Max,

Thanks for your replying.

I followed the steps but still can't flash with my Blackhawk USB560v2 System Trace Emulator.

Having the same problem as the post down below:

https://e2e.ti.com/support/processors/f/791/t/779510?AM4379-Uniflash-Error-when-trying-to-load-image

It seems like Uniflash only support command line interface with Sitara family processor...

Hi Yi-Lin,

Did you follow Pavel's suggested solution for that thread?

"I suspect the issue is caused by AM4379.ccxml. You need to create your ccxml file under CCStudio and selecting AM4379 do not looks correct to me for AM437x IDK board. In CCStudio menu, when selecting "Board or Device", select IDK_AM437x instead of AM4379. Check below user guide, it explains for AM437x EVM, and it is similar for AM437x IDK."

Hi Max

Yes, I have followed the suggestion of selecting device to IDK_AM437x.

And I got the same error in Uniflash v4.3.0 GUI as that thread.

Everything works fine by using the XDS100v2 on AM437x IDK board.

But we are using Blackhawk USB560v2 System Trace Emulator for developing and flashing the QSPI Flash on our custom board.

Using the same configuration file, Flash Programmer can be load into processor in CLI successfully.

At the next step of flashing the binary file, it needs to set the COM port of Emulator.

Since BlackHawk USB560v2 System Trace Emulator is an USB Device, it don't have COM port in Windows 10 environment...

Is there any method to set the USB port in CLI command?

Thanks

Hi Yi-Lin,

 I don't think you'll be able to set the JTAG connection up as a COM port.

The only way to download the image over uniflash would be to connect to the USB.

For more information check out the user hardware guide: http://www.ti.com/lit/ug/spruii2/spruii2.pdf

Specifically, the section on USB.

Thanks,

Max

Hi Max,

According to the Uniflash introduction from the link down below:

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#id275

Does that means AM437x IDK board still needs the UART interface to download data into flash device?

I can't just use JTAG interface to download my programmer into QSPI Flash Device.

Thanks,

Yi-Lin
