I see lots of kernels out there for the iMX233 and I have 4+ on my build server.
linux-2.6-imx: the source tree from Freescale based on the 3.2 kernel tree, lacks USB support.
linux-3.5.5: kernel.org, but no USB support
linux-3.6.0-rc2: from kernel.org + Koliqi patch set
linux-3.6: kernel.org, USB support kinda of working
I have spent many hours compiling and messing about with these kernels. All have had limited success. I would really like USB, GPIO, and battery charging all to work. Can anyone point me at a good source tree / patch set that works well on the micro board?
Thanks!
Did you ever find out which is the known to be good source/location?
I'm using OpenWRT which currently ships 3.12. Everything works well on my -MINI, except for maybe battery charging. (Don't have a battery myself, but I think there is still no kernel space driver for this yet.)
GPIO and USB work in OpenWRT for many month now.
HTH,
