Hello,
I am working on Cortex-A53 and using Cortex-A53 DSM Model in my design. We are getting Data Abort exception on a read to ROM address and ESR_EL3 register showing its a DECERR External error. MMU and Cache both are not enabled at this point where…
hi,
on a cortex a53, I would like to get the best of both worlds. Having dcache enabled but no page walk in case of a miss.
I want no memory protection because we manage the whole system ( kind of baremetal processes)

Hello everyone,

I've successfully setup the page tables for two levels covering…
Hello everyone,
I'm experimenting a bit with MMU after understanding its core principles. Specifically I can successfully enable it with an identity mapping for TTBR0 (no TTBR1) on a Raspberry Pi 3 (Cortex A-53, ARMv8 AArch64).
The next step I wanted…
