Hi all,
we use the i.MX28 from freescale.
Has anyone succeeded flashing a linux or rootfs image through the barebox
bootloader using a CAN bus connection?
We need it to make a field update of the target possible.
best regards

Not yet, but we can port the CAN stack to barebox. However, if you have
the space, I suggest to boot into a minimal Linux-System to run the
update there.

Hi Marc,
what is the effort to port the CAN stack to barebox?

Definitely more than implementing the "boot a minimal Linux (2-3 MB) and
do the update process there". And more error prone, for the minimal
update Linux basically we have all components (Kernel, CAN-Stack,
minimal Userspace).

It is just a matter of how much flash you have on the system. If there
is enough space, I'd always go for a Linux based solution.
