[U-Boot] Recommended AVR32 toolchain
Hi Andreas,
I'm trying to verify the correct build of all AVR32 boards. What is the recommended toolchain to use?
I tried the one that comes with Ubuntu:
sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude
But it does not work, I get the following build errors:
Building atngw100mkii board... avr-gcc: error: unrecognized command line option ‘-mno-init-got’ avr-gcc: error: unrecognized command line option ‘-mcpu=ap7000’ make[3]: *** [include/autoconf.mk] Error 1 make[3]: *** [include/autoconf.mk.dep] Error 1 make[2]: *** [silentoldconfig] Error 1 make: *** [sub-make] Error 2 avr-size: '/home/lab/dev/u-boot/out/all_avr32/u-boot': No such file avr-gcc: error: unrecognized command line option ‘-mno-init-got’ avr-gcc: error: unrecognized command line option ‘-mcpu=ap7000’ make[3]: *** [include/autoconf.mk] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: *** [include/autoconf.mk.dep] Error 1 'make -f /home/lab/dev/u-boot/scripts/Makefile.autoconf obj=include include/autoconf.mk include/autoconf.mk.dep' Failed make[2]: *** [silentoldconfig] Error 1 make[1]: *** No rule to make target `include/config/auto.conf', needed by `include/config/uboot.release'.

it depends, at least you should use a avr32-linux toolchain. The avr32-elf one builds u-boot fine but has some runtime flaws. For compile testing this would be Ok.
I tried the one that comes with Ubuntu:
sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude
Ouch, that is wrong. You got the avr 8-bit variant. There is no mainline avr32 gcc support! The patches come from atmel [1] and are for an outdated gcc version unfortunately. You cold use the pre-compiled avr32 toolchain provided by kernel.org [2]. I personally have never run this toolchain but others said it works.
Best regards

Hi Andreas,
The toolchain from kernel.org indeed works fine.
Thank you very much for your help!
Best regards, Vasili
