I've built my own toolchain using CLFS instructions currently found in my git repo. My toolchain consists of:
- Linux Headers from 2.6.36
- GMP 5.0.1
- MPFR 3.0.0
- MPC 0.8.2
- Binutils 2.21
- GCC 4.5.2
- uClibc 0.9.31 (with uClibc provided patches)
My kernel is from tmlind's OMAP tree, version 2.6.38-rc8. I started with the omap2plus_defconfig and modified it a little bit (although modification may not be needed, still have to check that).
I'm using the provided xM U-Boot but with a few slight changes to the boot args and boot up sequence:
- setenv console ttyO2,115200n8
- mmc init ${mmcdev}
- run loaduimage
- run mmcboot
I've made public gists of the boot console output and my kernel config, in case anyone is interested.
Next step is to get the CLFS embedded filesystem up and running on my xM!
EDIT: Thought my selection of ABI and triplets might be of interest as well:
- target triplet: armv7a-unknown-linux-uclibceabi
- ABI: aapcs-linux
- little endian
- hard float
- arm mode only (no thumb instructions)
- vfpv3 floating point hardware
