This patch need to be applied INSIDE the binutils folder! Use: patch -N -p0 --no-backup-if-mismatch \ -i ....../avr32/patches/binutils/2_22/binutils-2.22-avr32-full.patch This patch contains all the patches from single. It was generated by applying all of them and doing a new diff against the original. binutils-2.22-avr32-full.patch **** NOTES **** I tried the gas and ld test (make check), but this produced some errors. The same error happened with my build of binutils 2.20.1. I guess ATMEL didn't update the test cases for long time.
