I didn't touch any of the source yet. I'm downloading the 1/10/05 2.6.15 tarball ( ftp://ftp.linux-mips.org/pub/linux/mips/kernel/v2.6/linux-2.6.15.tar.gz )now to see if that fixes things. In response to Thiemo's message the error with (V=1) is: make -f scripts/Makefile.build obj=arch/mips/kernel /klocal/buildroot/build_mipsel/staging_dir/bin/mipsel-linux-gcc -Wp,-MD,arch/mips/kernel/.entry.o.d -nostdinc -isystem /klocal/buildroot/build_mipsel/staging_dir/bin-ccache/../lib/gcc/mipsel- linux-uclibc/3.4.5/include -D__KERNEL__ -Iinclude -D__ASSEMBLY__ -I /usr/local/src/linux-2.6/include/asm/gcc -G 0 -mno-abicalls -fno-pic -pipe -finline-limit=100000 -mabi=32 -march=mips32r2 -Wa,-32 -Wa,-march=mips32r2 -Wa,-mips32r2 -Wa,--trap -Iinclude/asm-mips/mach-mips -Iinclude/asm-mips/mach-generic -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -ffreestanding -O2 -fomit-frame-pointer -I /usr/local/src/linux-2.6/include/asm/gcc -G 0 -mno-abicalls -fno-pic -pipe -finline-limit=100000 -mabi=32 -march=mips32r2 -Wa,-32 -Wa,-march=mips32r2 -Wa,-mips32r2 -Wa,--trap -Iinclude/asm-mips/mach-mips -Iinclude/asm-mips/mach-generic -c -o arch/mips/kernel/entry.o arch/mips/kernel/entry.S arch/mips/kernel/entry.S: Assembler messages: arch/mips/kernel/entry.S:157: Error: opcode not supported on this processor: mips32 (mips32) `jr.hb $31' make[1]: *** [arch/mips/kernel/entry.o] Error 1 make: *** [arch/mips/kernel] Error 2 Also, assembler -v output: GNU assembler version 2.16.1 (mipsel-linux-uclibc) using BFD version 2.16.1 Thanks, Kurt Schwemmer > -----Original Message----- > From: Ralf Baechle [mailto:ralf@xxxxxxxxxxxxxx] > Sent: Monday, March 13, 2006 1:57 PM > To: Kurt Schwemmer > Cc: linux-mips@xxxxxxxxxxxxxx > Subject: Re: Cross compile kernel w/ buildroot toolchain > > On Mon, Mar 13, 2006 at 01:39:53PM -0700, Kurt Schwemmer wrote: > > > I got 2.6.15 "a while back" (>1 month). > > > > I'll try getting the most recent source.
