Attached are instruction how to get binutils, gcc and uboot mkimage for avr32 working on FreeBSD. Dont be put off by the avr32-linux target, the avr32 target is broken or at last i haven't been able to get it working, and it dosen't matter because no linux specific code is included in the end. I have no intrest in trying to get the toolchain into the freebsd tree until Atmel has submitted they're changes upstream, and the fact that some Atmel gcc patches seem to break other arch builds. I will post patches for FreeBSD/AVR32 later today. Assuming all files are downloaded to the same folder and toolchain will be installed to /crosstools and that /crosstools/bin is in you PATH. At the moment i got a hardcoded paths to /crosstools to build the kernel.

Maybe it works with the linux emulation, but i haven't been able to get it working on amd64 (only 32bit binaries avilable, but 64bit binaries are one the way). If you wanna try then the avr32gdbproxy app is avilable from atmels site (included in the toolchain packages) and more info about how to use it on: http://avr32linux.org/twiki/bin/view/Main/KernelDebugging Greets Arnar Mar Sig Valka ehfReceived on Mon Aug 11 2008 - 12:49:35 UTC
