Hey all,
Raspberry Pi 4B MMU seems to be enabled, as reported by openocd but gdb is
showing to run in a loop from aarch64-defaulit-exception.S file starting
from code line number 143 to 220.
>From what I can gather, it is being caused by the wrong MMU address.
Here's a RAM and MMU allocation sizes and base
MEMORY {
RAM_MMU : ORIGIN = 0x0, LENGTH = (0x1000 *
${AARCH64_MMU_TRANSLATION_TABLE_PAGES})
RAM : ORIGIN = 0x80000, LENGTH = 1024M
}
Relevant Openocd info
bcm2711.cpu0 halted in AArch64 state due to debug-request, current mode:
EL1T
cpsr: 0x200003c4 pc: 0x8e208
MMU: enabled, D-Cache: enabled, I-Cache: enabled
Info : New GDB Connection: 1, Target bcm2711.cpu0, state: halted
Any ideas?
Thanks,
Noor
