TMS320F28379D: parallel boot mode for both CPU1 and CPU2 - GPIO selection

Lenio Cacula

Part Number: TMS320F28379D

What is the recommended sequence of events when both CPU's are to bootload from parallel GPIO's? Should CPU1 finish its boot loading process, reassign GPIO's to CPU2 (GPIO69, 70, 63-58, 64, 65) and then send the IPC command to boot in parallel mode? Should the IPC command occur prior to assigning the GPIO's like the dual blink example? 

A detailed response will be highly appreciated. Thank you!

    Hello

    Your understanding is correct. Should follow the flow:

    1. CPU1 finishes booting via parallel
    2. CPU1 app starts
      1. App reassigns GPIOs to CPU2
      2. App sends IPC command to CPU2 to boot via parallel
    3. CPU2 begins booting via parallel

    Best regards
