Loading kernel from SPI NOR

Loading kernel from SPI NOR

Hi,

I have a custom board based on the i.MX53.  We are using barebox 2012.05.0
and booting the Freescale 2.6.35.3 kernel.  Our board has SPI NOR (m25p32)
and I saw there is a driver in a more recent barebox.  I pulled 2013.01.0
and added our board files but I can't seem to get the kernel to load.  I
used the uimage tool and the -i option reported back that it can read the
kernel and the -v option reported ok.  When I try and boot I see
arch_number and then nothing.

I'm continuing to dig in to see what I can find.  Any pointers to where I
can look is much appreciated.

Thanks,
Jeff

The first thing you should check is whether your kernel is stored
correctly on the NOR flash. try a:

erase /dev/nor0
cp /someimage /dev/nor0
crc32 -f /someimage
ls -l /someimage
crc32 -f /dev/nor0 0+x

(with x being the size of /someimage as output by ls -l)
