That's very similar to a 32bit rpi. I can understand why lightning
issues thumb2 instructions but can't understand why your system is not
happy with them.

Naming in ARM world sucks. ARMv7 can be indeed a Cortex-A8 and is indeed
in the case of a i.MX53.

This list helps:

Have you attempted to recompile by shifting the definition of
JIT_ARM_THUMB upwards in the file?
