TMS320C6748: STM32F207 mcu connected TMS320C6748 four HPI problem

Part Number: TMS320C6748

hi  Team:

As shown in the figure below, I use STM32F207 to connect four C6748 through HPI for communication. When I load two of them arbitrarily, the remaining two cannot communicate. How can I solve this problem?

    Hi David,

    In this case as I understand the MCU (STM32F207) is the master that initiates the communication with the C6748 DSPs, right? So can you identify if the root cause of your problem (only communicating with two C6748 at the same time) is in the STM MCU or the C6678 DSP? it seems the problem is in the MCU firmware, which is not supported in this forum.
