Hi, I am trying to use the WinARM (WinARM-20070505) for LPC2378. I took the example "C:\WinARM\examples\lpc2378_demo1" and try to add a dummy code to just blink LED's. But, I am getting some linker errors. So to single out the problem, I have only main.c and startup.S and removed all other files from the makefile. Even in the main.c I have removed all the other code and just have a while(1) loop to blink the LED's. With this again the same error happens (as mentioned below). Any suggestions are welcome. -------- begin (mode: ROM_RUN) -------- arm-elf-gcc (GCC) 4.1.2 (WinARM 4/2007) Copyright (C) 2006 Free Software Foundation, Inc.

There should be something wrong with your link script. Attach your code and link script, then people can help you

Attached files:Hi, The linker script is attached. Also the main.c, main() is as follows.

Startup.S is also needed. i don't know how section .stack is assigned.

I found where the error comes from:
In your linker script, the lines below hide a mistake:
. = ALIGN(4);
_bss_end_ = . ;
PROVIDE (__bss_end = .);
.stack ALIGN(256) :
{
*(.stack)
*(.STACK)
PROVIDE (_stack = .);
. = ALIGN(4);
} > RAM
I imagine that you want the .stack section to be 256 bytes aligned in
the RAM region, but the line ".stack ALIGN(256)" will set .stack to
address 0x700
, and obviously this address is not within RAM region
You should do like this:
. = ALIGN(4);
_bss_end_ = . ;
PROVIDE (__bss_end = .);
. = ALIGN(256);
.stack :
{
*(.stack)
*(.STACK)
PROVIDE (_stack = .);
. = ALIGN(4);
} > RAM
