Hi all,
I try to run this simple program to set up the tools. I also reused the files from hello-uart (mc.h, board.h, reset.S ...) to compile it. #include "board.h" int main() { int i; i = 5; } the asignment compile to: l.addi r3,r0,0x5 l.sw 0xfffffffc(r2),r3 When i run it and try to print i in gdb it has the value 0 and not 5 after the asignment. I also get thim message from the simulator: WARNING: memory write to 0xffffffd0, non-write memory area (value 0x00000005) What is going wrong? |

Problem fixed. I changed the memory section in sim.cfg to:
section memory
type = unknown
nmemories = 1
device 0
name = "RAM"
ce = 0
baseaddr = 0x00000000
size = 0x00800000
delayr = 1
delayw = 1
enddevice
end
