SK-AM64B: IPC notify echo - MCU + SDK is not loading

Part Number: SK-AM64B

Dear TI team,

I was trying to check the IPC notify echo using MCU + SDK . I have imported 'ipc_notify_echo_am64x-sk_system_freertos_nortos' and tried to  load the application as mentioned in Link1 & Link2 . I was able to select a core and tried to connect a target, say A53 and it proceeds for a few moments and not progressing after 'Waiting for first frequency change request' message in the console (please refer the image attached). Am I missing some important steps? Kindly guide me? I have successfully checked a few examples like gpio_led_blink, but  the IPC example is not loading 

Thank you

Chris

    Hi Chris,

    This issue is due to the GEL scripts trying to initialize DDR which is already initialized by SBL. To prevent this, use AM64x in Board or Device option as shown. This option uses only CPU_reset.gel initialization script which does not do the DDR initialization.

    Regards,

    Dear Prashant,

    Thanks a lot for the quick response and the issue got resolved. The debug logs were not showing in CCS console for the example application, so i referred Link1 & Link2 and now the messages are shown as per the IPC example  page . It could have been better, if these two information are available in the IPC example  pages.

    Thank you

    Chris
