SK-AM62: Replace the existing R5F firmware binary with the new one

JaeWook Kim
Intellectual 370 points
Part Number: SK-AM62

Dear TI Expert,

HW : AM62x SK-EVM

SW : Processor SDK 8.5, MCU SDK 8.5

I'm trying to replace R5 firmware binary with new one I built.(examples/drivers/ipc/ipc_rpmsg_echo_linux/am62x-sk/r5fss0-0_freertos)

I created new tispl.bin as following steps.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_06_00_42/exports/docs/linux/Foundational_Components_IPC62x.html?highlight=ipc_echo_testb_freertos_mcu1_0_release#getting-started-with-ipc-linux-examples

1). Build R5 fw example

2). R5 firmware file copy

 I copied the "am62-mcu-r5f0_0-fw" file because there was no "ipc_echo_testb_freertos_mcu1_0_release.xer5f" file in Release directory, but I'm not sure if this is correct.

cp ~/ti/workspace_v12/ipc_rpmsg_echo_linux_am62x-sk_r5fss0-0_freertos_ti-arm-clang/Release/am62-mcu-r5f0_0-fw <path_to_linux_installer>/board-support/prebuilt-images/ipc_echo_testb_mcu1_0_release_strip.xer5f

3). Build u-boot

make u-boot

4). Flash tispl.bin and u-boot.img

If I try booting after flashing in the above step, device is stuck at the log as shown below.

Please correct me If i'm wrong. or Please let me know how to replace R5 firmware with new one.

Thanks&Regards,

Jaewook

    Hi Jaewook,
    

    I can replicate the issue on my end. I follow the same steps as yours & get the same behaviour.
    

    Interestingly, if I use the firmware generated by building the IPC example using SDK makefile, then the A53 U-Boot SPL boots fine. Could you please once try the same approach and let me know if it works.
    

    You can build the IPC example from SDK makefile using the below command run from the MCU+ SDK Installation Directory:
    

    gmake -s -C examples\drivers\ipc\ipc_rpmsg_echo_linux\am62x-sk\r5fss0-0_freertos\ti-arm-clang all
    

    Then, use the generated firmware named am62-mcu-r5f0_0-fw to replace the prebuilt one in PSDK.
    

    Regards,
    

    Prashant

    Hello Prashant,
    

    

    I used to build it using CCS.
    

    However it is working well now if I build it using makefile as you said.
    

    Thanks for the good solution.
    

    

    Thanks&Regards,
    

    Jaewook
