This one is the problem.
void main(void)
{
__asm
nop
ldw x, #(_main >> 8)
nop
__endasm;
}
results in this listing (comments removed):
_main:
000000 9D [ 1] 87 nop
000001 AEr00r00 [ 2] 88 ldw x, #(_main >> 8)
000004 9D [ 1] 89 nop
000005 87 [ 5] 94 retf
And this binary:
:04F000008200F00892
:1DF00800AE00002707724F00005A26F9AE00002709D6F02AD700005A26F7CCF004F9
:04F00400AC00F02547
:06F025009DAE00F0C28761
:00000001FF
As you can see, the second nop got overwritten by 0xc2. Whenever I use
#(sym >> 8) where a 16-bit value is expected, I see the following
instruction being overwritten.
