Hi all,
well i have some news with this coldfire 5307 issue,
i disassembled and put some loop as opcodes here and there in the kernel
(4ef9 0000 XXXX jmp XXXX ) as a very rude debug.
The issue is just at the beginning:
Dump of assembler code for function _text:
0x00000400 <_text+0>: nop
0x00000402 <_text+2>: movew #9984,%sr
0x00000406 <_text+6>: moveal #0,%sp <--- Issue is here
0x0000040c <_text+12>: movec %sp,%vbr
0x00000410 <_text+16>: movel %sp,0xe8944 <_ramvec>
See arch/m68knommu/platform/coldfire/head.S
CONFIG_VECTORBASE is the #0
There are a few config options, you'll see them as macros in coldfire/head.S
and can trace their names to the Kconfig or vendor/ configs.
Also you can customize own head.S if PLATFORM_SETUP is not enough for
you.
