TDA4VM: boot

Part Number: TDA4VM

Hello Experts:

        I met a problem while i trying to boot my App. I asked a releated problem :TDA4VM: How to use OSPI to boot RTOS and QNX - Processors forum - Processors - TI E2E support forums

According to the suggestion, i add a delay time at mcu1_0 , so that , QNX and mcu2_0(bsp) could running correctly and to avoid  SCI failures. And yes, it can boot mcu1_0 and the others successfully. But the problem is that some funcitons seems couldn't work correctly,(eg. DP, PCIE).

and the , if we remove the SBL_SlaveCoreBoot(MCU1_CPU0_ID, 0, &k3xx_evmEntry, SBL_REQUEST_CORE), the result is ok(DP, PCIE works fine), but it will not jump to my app.

So, i doubt  that , when i jump to my app(it will start sci server too.), the sci communication will be disconnect with the ohter cores. and after the app start sci server angin, Will the sci communication has some problem? 

Could you help me figure this problem out?
