AM263P4-Q1: Does RBL reset all the memory regions?

thanks guys,

I want to store some data in memory and keep it over a warm reset. 

In my case, if I use the Bank 6 to save the data, does it will stay after a warm reset?

Thanks

Hi Sahana,

I tried to write a byte into 0x702FFFF0, then do a software reset. But the data was reset to 0.

I write data and do a reset by a CAN command and read data from that address by another CAN command.

From the debugger, I could see the 0xAA was write in and reset occured as debugger lost communication.

Then when I read data by another CAN command, I got 0x0.

Any idea?

Thanks

Could you confirm that you're doing a software warm reset by writing into " MSS_TOPRCM_WARM_RESET_REQ" register? And do you see the warm reset occurring by reading the register "MSS_TOPRCM_SYS_RST_CAUSE" ? 

Hi Sahana,

I found the issue that is my SBL init all the memory banks.

Thanks
