I've soldered a wire to the XOMCCI pin on Odroid-XU+E. When pulled to
Vdd via 100k (original configuration), the fault is "imprecise external
abort (0x1406)" (as above). When pulled to ground, the fault is
"imprecise external abort (0x406)". This is consistently reproducible.
AFAICT, from ARM reference [1]: the 5 status bits in both cases are
"Asynchronous external abort." and the difference is bit 12 "external
abort type:" when pulled to Vdd, caused by "AXI Slave error," when
pulled to ground, caused by "AXI Decode error".
Any pointers on further differences between SMDK5410 and ODROID-XU that
are preventing the patch from booting? Thanks in advance.
