RTOS/TDA2P-ACD: Board reboots at startup

Part Number: TDA2P-ACD

Tool/software: TI-RTOS

Hi all,

 

We have custom made board with TDA2p chip. We have following problem: If the board is on for some time and chip is worm and if we reset the board, it will periodically reset itself, every 1-2 seconds. So, this is happening sometimes and it seems it's random. This is UART log:

TDA2Px SBL Boot

DPLL Configuration Completed

Clock Domain Configuration Completed

Module Enable Configuration Completed

TI EVM PAD Config Completed

TDA2Px DDR Configuration

Please, can you help us to debug this problem? What we can do in order to find out where could be the problem - read some register ... ? Can high CPU temperature produce RESET?

 

Best Regards,

Stefan.
