Hi,
I am trying to read the TTBR0_EL register using the assembly instruction provided in the arm documentation, but the kernel responded with illegal instruction error. Is there any other way to read the system control register? any utility/CLI available like to export to some log files?
Thanks,
Nav

You can use hardware debug to see register,or you can see qemu reference:https://elixir.bootlin.com/qemu/v2.3.0-rc3/source/target-arm/helper.c
