TMDS64EVM: Flash SOC Initialization Binary

Andrea Migliaccio
Prodigy 195 points
Part Number: TMDS64EVM
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

After installing Python3 and related packages, connecting the EVM power cable and the UART cable, and configuring the UART port (seen as COM5) in CCS, I set switches 2-3 in the UART Boot-Mode.

When power-on the EVM, the UART terminal on CCS correctly reports the SOC ID followed by character "C" printed every 2-3 seconds; after this, I closed the UART terminal.

So, running in the command prompt the command: 

python uart_uniflash.py -p COM5 --cfg=sbl_prebuilt/am64x-evm/default_sbl_null.cfg

It gives me the following error:

[ERROR] XMODEM send failed, no response OR incorrect response from EVM OR cancelled by user,
Power cycle EVM and run this script again !!!

Thanks for the support

    Hi Andrea,

    Thanks for your query.

    Is it failing every time or it happens randomly?

    At which command it is failing? Can you please provide full error logs?

    Regards,

    Tushar

    It fails every time, in correspondence of the 2°command, as I report below:

    Hi Andrea,

    Thanks for sharing the above error logs.

    Can you please tell which device type are you using? Is it GP or HSFS?

    Please follow the steps mentioned at faq-am6xx-how-to-check-if-device-type-is-hs-se-hs-fs-or-gp and share the results.

    Regards,

    Hi Andrea,

    Thanks for sharing the detail.

    Andrea Migliaccio said:

    This is the cause of the issue. The device type is GP and you are trying to flash an HSFS image which is not supported by GP devices.

    You will need to flash GP images to initialize the GP device. From SDK 9.0 onwards, GP devices are no longer supported. 

    Please use the HSFS device or either use the SDK v08.06.

    Thanks Tushar!!

    With the SDK v08.06 the command runs correctly!
