Re: bringing up a 2GB nitrogen6x -- SUCCESS
peter green wrote:
Fourth try: Google for "nitrogen6x wheezy armhf", this took me to
http://www.armhf.com/index.php/boards/nitrogen6x-sabre/ , the image
from there booted fine but only saw 1GB of ram. Further investigation
shows that the boot process involves two versions of u-boot. The first
(presumablly loaded from the nitrogen6x's boot flash) sees 2GB but the
second (presumablly loaded from the SD card) only sees 1GB.
I took another look at that page and noticed it had a link to "how to do
it yourself" , I followed that link to
http://www.eewiki.net/display/linuxonarm/i.MX6x+SABRE+Lite and found
some instructions for getting a patched u-boot source.
Unfortunately the config he was using was based on the sabre light
config (which afaict is locked to 1G ram) and not the nitrogen6x config
and further his u-boot assumed a partitioning structure which was
different from the one used in the image I had (in particular it had a
seperate boot partitions).
Still with a bit of hacking (mostly copying stuff from the sabre lite
config and a lot of trial and error I managed to get a u-boot config
that would both see all the ram and successfully load the kernel from
the image I had. I've attached it here in case anyone else finds it useful.
So it's running wheezy (with a non-debian "3.9.1-imx4" kernel supplied
with the image from armhf.com), seeing all the ram, seeing the sata hard
drive and seeing USB sticks, I haven't tried any of the other hardware.
