hi all,
when i am trying to build my own boot loader, i am getting an error like,
mmumacro.s(39) : error A0034: undefined symbol: FORCE_TGTCPU
but in the command line i alerady have given like set FORCE_TGTCPU=ARM920
what i missed?
the same code works fine for the armintegrator eboot.
what went wrong?
regards
Sujith
