fix(panic): fixed cache error being reported as illegal instruction On riscv chips accessing cache mapped memory regions over the ibus would result in an illegal instructions exception triggering faster than the cache error interrupt/exception. Added a cache error check in the panic handler, if any cache errors are active the panic handler will now report a cache error, even if the trigger exception was a illegal instructions. 2023-11-27 20:57:44 -05:00
