The 64-bit kernel has a binary compatibility layer that allows you to use 32-bit software with no changes. Just use a 64-bit compiler, for now that's probably still the egcs 1.1.2 / binutils 2.9.5 based mips64-linux / mips64el-linux tool chain. Using your old .config file do a "make ARCH=mips64 oldconfig" etc. The resulting binary file will be a 32-bit ELF file so you can just feed that to your firmware for booting as usual. Problems may be hit along the way ;-) Ralf
