Part Number: SK-AM62-LP
Other Parts Discussed in Thread: AM623

Tool/software:

Hi,

We are using AM623 processor with the SDK version am62xx-evm-11.00.09.04. We want to know the procedure for booting from UART. We are trying to load the U-boot binaries from UART using Tera term X/Y modem. But it's not loading though the prints are coming from SOC as like below:

So, let me know the procedure on how to load the U-boot binaries from Tera term/minicom X/Y modem file transfer.

Thanks in advance.

Regards,
Salih

    We have tried the same procedure. Those 3 commands are executing properly. But the boot logs are not coming in the console.
    Here, CCCCCC dumping in /dev/ttyUSB0. So, which one will be our MAIN-UART and from where we have to load those three files?

    Please clarify it on the same.

    Thanks in advance.

    Hi Salih,

    I hope you are using the correct images for am62x-lp-evm, you can find the pre-built images for am62x-lp-evm in <processor-sdk-path>board-support/prebuilt-images/am62xx-lp-evm folder. If you are building the u-boot files again then use this command:

    make u-boot PLATFORM=am62xx-lp-evm -j32

    If the correct image is being used here, can you please once disconnect the UART terminal from CCS and then run the commands for uart boot. Once all these commands are executed, you can then connect to the UART terminal and CCS to verify the u-boot boot.

    Best regards,

    Meet.
