SK-AM62A-LP: DFU Output

DIM
Prodigy 70 points
Part Number: SK-AM62A-LP

Tool/software:

Hello,

I am attempting to run DFU on the SK-AM62A-LP development board. I've been following the steps outlined in the SDK here, but I am seemingly unable to make it passed flashing the bootloader for the R5 (tiboot3.bin).

After running "dfu-util.exe -R -a 0 -D tiboot3-am62ax-gp-evm.bin", I get the following output:

C:\ti_yocto>dfu-util.exe -R -a 0 -D tiboot3-am62ax-gp-evm.bin
dfu-util 0.9

A valid DFU suffix will be required in a future dfu-util release!!!

There are no messages printed to the serial port. The DFU device re-enumerates after this failure.

I was wondering if someone could post the expected serial console and dfu-util.exe output after successfully flashing tiboot3.bin?

Thanks

    I am going to try this on my AM62A TI EVM and let you know the expected results one can see. You can expect this in few business days.

    Meanwhile can you please try the following command:

    Instead of 

    dfu-util.exe -R -a 0 -D tiboot3-am62ax-gp-evm.bin

    Try the following:

    dfu-util.exe -a bootloader -D tiboot3-am62ax-gp-evm.bin

    After trying this can you check if you are able to see the logs on the UART console? Also make sure your UART console is configured at a baud rate of 115200.

    Looking forward to your response.

    Regards,

    Vaibhav
