I suspect that it is sufficiently old that it doesn't have support for assembling for the 920. Possible solutions to this are: - Upgrade binutils - Target a different processor (try StrongARM for example). - Use -march=armv4t -tune=arm920t (This will give you the same code as with -mcpu=arm920t, but will pass armv4t to the assembler instead (it's far more likely to accept that)) R. ------ Want more information?
