AM3352: U-boot debug

Nomo

Part Number: AM3352

Hello,

My customers want to debug u-boot in Processor SDK for AM335x on their custom board.
And they want to repeat on and off for their custom board; however, they want their board to keep the debug connection.
Could you tell me the way to debug u-boot and keep debug connection for device on/off?

Best Regards,
Nomo

    What do you mean by "debug connection"? The JTAG connection? I don't think there is any way to keep that active during a board power cycle, you would need to re-attach and re-establish the debugger session once power is restored and the device is accessible again. This is something that you could automate however, depending on your environment.

    Please share some more specific details about what you are trying to do and we might be able to come up with a better suggestion.

    Thanks and Regards,
    Andreas

    Hi Andreas-san,

    Thank you for your reply.
    Your understanding is correct. I meant "debug connection" as the JTAG connection.
    And I can understand there is not any way to keep that active during a board power cycle.

    Best Regards,
