Hi experts,
I try to use ARM development studio to debug bootloader and view MMU table contents.
But MMU window can not display the MMU table and shows that "Unable to read from register SCR-EL3".
How can I do to check MMU table?
Current board is running on EL2 with 64bit, CPU is cortext-A73.
ARM development studio version: 2023.1
Thanks for your attention!
Best Regards,
Yan
Thanks for testing. Sorry that "Follow system" to "Non-Secure EL2 (AArch64)" didn't work.Yes, I think the issue is caused by secure debug being disabled. Please let us know if it works when enabled.Stephen
Hi，
When secure debug is enabled, MMU table can display.
However, not every board's secure debug can be enabled, so it is still a problem when non-secure world need check MMU table.
