Hi!
Did you get a linker script that works? I have the same problem. I was using CW and its script is not that compatible with GCC. Like WRITEW does not exists etc. See the file below. Some parts ar easy to adjust, like KEEP_SECTION is changed to KEEP at the correct place, but WRITEW and EXCEPTION stops me.... If I delete to much the linker will say "undefined referencce tp '__bss_start__ " and "__bss_end__".
In short: How to make the CW linker file working in GCC?
Very happy for answers. :smileyhappy:
