I found this documentation: https://cs140e.sergio.bz/docs/ARMv8-Reference-Manual.pdf
On page D7-2464, it mentions that SCTLR_EL1 of the Non-Secure world can be accessed from EL3.
I am using ARMv8 FVP.
Can anyone provide guidance on how to access and update SCTLR_EL1 of the Non-Secure world (Linux) from EL3?
SCTLR_EL1
Thank You for your reply. Yes, the OS was running in EL2, and I was able to write to it using the sctlr_el2 register. Thank You for your guidance.
