Ok, I'll try this out.

Ok, I'm using the X-Loader from git://git.igep.es/pub/scm/x-loader.git,
tag v1.4.4-3, on top of which I apply
http://git.free-electrons.com/training-materials/plain/lab-data/sysdev/u-boot/x-loader-1.4.4-3-igep-nand-support.patch
to add support for the NAND-based IGEPv2 rev6.
In terms of U-Boot, I use U-Boot 2011.12, on top of which I apply
http://git.free-electrons.com/training-materials/plain/lab-data/sysdev/u-boot/u-boot-2011.12-igep-nand-support.patch
to add support for the NAND-based IGEPv2 rev6.
To make things easier if you don't need to rebuild those, I've put
online pre-built binaries of X-Loader and U-Boot I'm using:
http://free-electrons.com/~thomas/pub/igep-serial-problem/.
Thanks,
Thomas
