I would like to debug my SoC with CortexA-53 core from the reset vector.
For this, I am writing the EDECR.RCE bit and does a warm reset.The core is getting reset and halt at reset vector. The status is also found to be correct from the EDSCR register.But i Am not able to properly debug the core afterwards. Ican read and write the registers. But cannot do the step operation.Do I need to do any other initialization for this?
It is likely that you cannot debug from reset vector. As often in these SoC some ROM code runs first. Which then load the boot loader.
Check out the manual, it will tell you more about the boot process.
Okay. Thank you Bastian for the support :)
