Part Number: TDA4VM

Hello Team,

       I put my own code on mcu1_0 core, my current requirement is OTA update of this code, now the problem is that SYSFW also runs on mcu1_0, will it affect SYSFW normal operation when I update this code OTA? What are the solutions to update the code on this core?

       Looking forward to your reply.

    Hi

    The way you would be updating the firmware would be using an A/B partitioning method:

    1. Boot from partition A

    2. Update to partition B

    3. Change some NVM register to mark that the next boot should happen from B

    4. Reboot and boot from B. Here, in case of a failed boot, you switch back you fallback to booting from A.

    In such a case there would be no effect in your current boot and also SYSFW will execute normally as the update takes place post a reset.

    Regards
