Buenas Guillermo,
- I used OSELAS arm-v5te pre-build toolchain (ubuntu repositories).
- I got two working kernels (one using friendly arm 4.4.3 toolchain and the other with the CodeSourcery 2009q3).
- With those two kernels, I also got a fully working rootfs (burned into nand using superboot) and i get the system up & ready, but:
- with FA - I cannot compile udev, the used glibc version for such toolchain seems lower than 2.10, so I get errors compiling udev ('accept4' related).
- with CS 2009q3 - everything alright but, the specific version of binutils used for compiling the toolchain is not publicly available (I suppose it was a custom build from CodeSourcery) so I cannot use the exact same binutil version (not a big problem but..)
- with the prebuild arm5vte oselas version, after burning to the board, the kernel get extracted and then .. no output, system hang.
- I also used kernel from FA as source, but some modifications were done, i.e (remove initramfs, removed cpio file, ...)
- I am currently testing the system with newer CodeSourcery version (2013.11-33), but i have the same 'problem', custom binutils build.
You mentioned that you built a customized arm-v5te toolchain (well you don exactly say so, but given I got no good results with the default configuration, I will suppose that), Did you add/remove any specific FLAG for the toolchain compilation (besides mtune)?
Regarding the barebox, I am pretty interested. I was planning also to try it but I have no more available hours in the day, ;). Please keep me up with you progress and let me know if you need anything.
