I get the same 'wrong compiler' situation when compiling for 5282EVB with m68k- elf-gcc 3.4.0, with the error: make[1]: Leaving directory `/home/vng/u-boot/post/cpu' m68k-elf-gcc -Wa,-gstabs -D__ASSEMBLY__ -g -Os -ffixed-d7 -msep-data -D__KERNEL__ -DTEXT_BASE=0x20000 -I/home/vng/u-boot/include -fno- builtin -ffreestanding -nostdinc -isystem /usr/lib/gcc-lib/i386-redhat- linux/3.3.3/include -pipe -DCONFIG_M68K -D__M68K__ -m5307 -c -o cpu/mcf52x2/start.o /home/vng/u-boot/cpu/mcf52x2/start.S /home/vng/u-boot/cpu/mcf52x2/start.S: Assembler messages: /home/vng/u-boot/cpu/mcf52x2/start.S:316: Fatal error: Tried to convert PC relative conditional branch to absolute jump make: *** [cpu/mcf52x2/start.o] Error 1 with limited cross-compiling experience, I'm really stuck. Hopefully someone will be kind enough to give some pointers. best regards, Vince
