What OS? Linux, or an RTOS?

If linux, then you would need to remove the cpu idling

You can also add a watch window in SDK if you want to monitor a memory region.

Hii

But i have already disabled the CPU_IDLE boot argument in the u-boot.

Are there any other reasons for that error?

Thankyou

Can you access this address wothout the OS running? ie you just program the PSU (either using the psu_init.tcl, or the fsbl)

I would just use the watch window in SDK. It is safer
