Hi,

I am quite new to barebox. Before I had little bit experience in u-Boot.

My Barebox version is: barebox 2012.03.0-00162-g3f84abc-dirty (Sep 24
2012 - 10:51:42)

I can mount a Linaro freescale mx53 sd-card setup. I think it has one
Fat8 partion, because Fat32 and Fat16 are not recognized by my barebox
version.

When I boot the uImage, it complains about not setting the "root="
parameter, when I give it as an argument it does not work.

In my u-Boot setup all I need to do was write:

setenv bootcmd "fatload mmc 0:2 0x70800000 uImage;bootm"
setenv bootargs "console=tty0 console=ttymxc0,115200n8
root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro"

Maybe this is a version isuue? I managed to build the latest kernel
what is the procedure to "flash" the new barebox.bin? Can I use the cp
command for this, or do I need to flash it via OCD? If so what are
good tools in linux to achieve that task?

OK a lot of questions. Most probably already answered, but had not
found google.

Thanks for help and sorry for repeating questions already answered.
