TDA4VM-Q1: Processors forum

Part Number: TDA4VM-Q1

Hi TI Expert,

As I understand, TDA4 startup flowchart: 

TDA4 Power up-->POR-->DMSC-->MCU domain-->Main domain;

Higher real-time modules are designed to MCU domain currently, for example: customers require some peripherals can work within 0.5s after power up.

if we move this peripheral module to main domain because SPI interfaces of MCU domain are not enough, does main domain support fast boot with RTOS

and this module can work within 0.5s after power up ?

Please give us suggestion.

Thanks,

Joseph

    Hi Joseph

    Can you help us understand the overall system use case?

    The main domain R5Fs can be started well within 500ms (0.5s), but what is the order you want the cores to boot and what is the intended functionality? Also, are they running freeRTOS?

    Regards
