Check - when in doubt via instrumenting the calls - if the regions at the faulting addresses are
actually mapped -> arch_map_memory_region.
arch_map_memory_region 0x48020000/0x48020000/0x00001000 0x00000093

Created cell "AM57XX-EVM-timer8-demo"
Page pool usage after cell creation: mem 62/4073, remap 6/131072
Each region from the am57xx-evm-ti-app.c are mapped.
Using the CCS debugger I started the inmate and paused it immediately on inmate_main() entrance
and checked memory referenced by TTBR0 register.
TTBR0 = 0x00017000
Is that TTBR0_EL1 or EL2?
I think that is EL1 as the CPU in the SVC mode.
0x0000017000 00019003 00000000 00000000 00000000 0001A003 00000000 00000000
00000000
Looks like only 2 last regions are mapped (application memory and communication
regions)
None of the peripherals regions are mapped, or may be I don't see them.
If we are talking about TTBR0_EL1: Since your old version, imates gained MMU support. That means you
now need to map additional memory (beyond the first 2M or so) into the guest's page table.
I'm not sure where I need to map this additional 2MB to. The DDR for the inmate is mapped to VA 0x0/
PA 0xee000000 size 8MB. Where do I need to add this 2MB?
Thanks,
