TDA4VM-Q1: TDA4 boot fail issue

Part Number: TDA4VM-Q1

Hi TI expert,

We are using TDA4VM-Q1 to develop a product.When we do some power on/off test, we found some issues.

We power on the board,all the power is well,the program will stop at very beginning.The program would stop at 0X0C which means trigged prefetch command unnormally.

Then compare the data in the DRAM between when it pass and fail. We found some of the DRAM data are wrong when it boot failed.

The data  read and write  of the NOR flash is normal. Only after these data transfered to DRAM, then we found some wrong data in the DRAM.

This phenomenon is easier to replicate at higher temperatures(85℃).

I attached the data in the DRAM of boot fail and pass

Have you ever encountered this issue before and maybe can give some help or hints of this issue?

Thanks
