One thing I noticed that when I move the xipImage below the DRAM base address, the kernel freezes:
...
Mount-cache hash table entries: 1024 (order: 0, 4096 bytes) Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes) [freeze]I think it happens when the scheduler gets started. Any idea what could go wrong here?
I ran into a similar issue on STM32F4 recently - hanging there, or:
Unhandled exception: IPSR = 00000006 LR = fffffff1

My debugging indicated that %pF was not working, used among others in checking for blacklisted initcalls. Disabling CONFIG_KALLSYMS worked around this, so I assume something there is not compatible with XIP...
