hi, i have been working with ecos for a couple of months now. I had no problem at all with a 8 months old repository source files and my own port for my target board. After some problem with my working environment and updating the ecos source files, i can't have my old work and my new code running on the board. It seems that my code always go through the same steps and finishes by an exception abort data.
Here is the code where it fails: 0x80020070 <start>: ldr r0, [pc, #1020] ; 0x80020474 <.init_flag> 0x80020074 <start+4>: ldr r1, [r0] 0x80020078 <start+8>: cmp r1, #0 ; 0x0 0x8002007c <start+12>: bne 0x80020078 <start+8> 0x80020080 <start+16>: ldr r1, [pc, #196] ; 0x8002014c <init_done> 0x80020084 <start+20>: str r1, [r0] 0x80020088 <start+24>: mov r0, #0 ; 0x0 0x8002008c <start+28>: ldr r1, [pc, #988] ; 0x80020470 <.__exception_handlers> 0x80020090 <start+32>: cmp r7, #19 ; 0x13 0x80020094 <start+36>: beq 0x800200a0 <start+48> 0x80020098 <start+40>: ldr r2, [r1, #40] 0x8002009c <start+44>: str r2, [r0, #40] 0x800200a0 <start+48>: ldr r2, [r1, #24] 0x800200a4 <start+52>: str r2, [r0, #24] <-- this line fails on my old and new programs It ends up in an abort data: 0x00000010 swp r1, r3, [r2] Someone has a hint to solve this problem??
