Hello. I am trying to cross-compile uClinux kernel 2.4.x for the Atmel AT91 board. I AM able to compile uClinux 2.6.x successfully for the Atmel board; however, I need 2.4.x to compile.
What code base are you working from? Which version of uClinux-dist? Regards Greg
Compiling 2.6.x I simply set CROSS_COMPILE in the menuconfig and went about my way. It appears less straightforward in the 2.4.x build. To override the hard-coded "CROSS_COMPILE" and "KERNEL_CROSS_COMPILE" I modified uClinux-dist/vendors/config/armnommu.arch so I could override the cross compilation variables. Then I ran: CROSS_COMPILE=/usr/local/arm-uclinux-gcc-3.4.3/bin/arm-uclinux-elf- KERNEL_CROSS_COMPILE=/usr/local/arm-uclinux-gcc-3.4.3/bin/arm-uclinux-elf- make linux Where: ls /usr/local/arm-uclinux-gcc-3.4.3/bin/ arm-elf-addr2line arm-elf-flthdr arm-elf-objcopy arm-uclinux-elf-addr2line arm-uclinux-elf-flthdr arm-uclinux-elf-ld arm-uclinux-elf-run arm-elf-ar arm-elf-g++ arm-elf-objdump arm-uclinux-elf-ar arm-uclinux-elf-g++ arm-uclinux-elf-ld.real arm-uclinux-elf-size arm-elf-as arm-elf-gcc arm-elf-ranlib arm-uclinux-elf-as arm-uclinux-elf-gcc arm-uclinux-elf-nm arm-uclinux-elf-strings arm-elf-c++ arm-elf-gcov arm-elf-readelf arm-uclinux-elf-c++ arm-uclinux-elf-gcc-3.4.3 arm-uclinux-elf-objcopy arm-uclinux-elf-strip arm-elf-c++filt arm-elf-ld arm-elf-size arm-uclinux-elf-c++filt arm-uclinux-elf-gccbug arm-uclinux-elf-objdump genromfs arm-elf-cpp arm-elf-ld.real arm-elf-strings arm-uclinux-elf-cpp arm-uclinux-elf-gcov arm-uclinux-elf-ranlib arm-elf-elf2flt arm-elf-nm arm-elf-strip arm-uclinux-elf-elf2flt arm-uclinux-elf-gdb arm-uclinux-elf-readelf Am I using the wrong toolchain version? So far I haven't found anything for sure specifying a specific version of the gnu arm-uclinux compiler toolset for uClinux kernel 2.4.x. I may just be missing it. The error I see appears to start with the compilation of assembly units: /usr/local/arm-uclinux-gcc-3.4.3//bin/arm-uclinux-elf-gcc -D__ASSEMBLY__ -D__KERNEL__ -I/home/Virtual_Machines/linux_kernels/uClinux-dist/linux-2.4.x/include -DNO_MM -mapcs-32 -march=armv4 -msoft-float -c -o entry-armv.o entry-armv.S entry-armv.S: Assembler messages: entry-armv.S:1495: Warning: destination register same as write-back base entry-armv.S:1721: Error: undefined symbol TSS_FPESAVE used as an immediate value The above text is the first error. There are many more assembly errors. Any help would be appreciated.
