[U-Boot] Recommended AVR32 toolchain

[U-Boot] Recommended AVR32 toolchain

[Vasili Galka]

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?

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.

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The patches come from atmel [1] and are for an outdated gcc version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.

Hi Andreas,

The toolchain from kernel.org indeed works fine.

Thank you very much for your help!

Best regards,
Vasili
