Hi Ben,
That's the trace I got:
0xd2a8: BL
0x876c: MOV_REG_IMM_SHIFT
0x8770: STMDB_WB
0x8774: SUB_IMM
0x8778: MOV_REG_IMM_SHIFT
0x877c: BL
0x8758: MOV_REG_IMM_SHIFT
0x875c: STMDB_WB
0x8760: SUB_IMM
0x8764: SWI Fault (software, 0x69) pc=0x8764
and this is the piece of the original code where the error is happening:
00008758 <_swiwrite>:
8758: e1a0c00d mov ip, sp
875c: e92dd800 stmdb sp!, {fp, ip, lr, pc}
8760: e24cb004 sub fp, ip, #4 ; 0x4
8764: ef000069 swi 0x00000069
8768: e91ba800 ldmdb fp, {fp, sp, pc}
SWI is software interrupt, right? Looks like I'm trying to execution
function 0x69 that doesn't exist? is this right?
Why would this happen? This is such a simple example. And one more
question..., which configuration is being used (besides ARM processor)
once I haven't specified any configuration file, let alone created some
configuration.
thanks,
Cristiano.
