Ok, thanks. I will take a look. I think for that scenario I
do not need fastboot. Once I have barebox in RAM I can do
barebox_update to flash it in NAND, reboot and then run a script from
USB
that created partitions in NAND and copies FIT image(which contains
kernel+rootfs) on NAND
Fastboot would be helpful if I could flash the NAND without
running anything in target's RAM initially( no barebox nor Linux).
My goal is to have a target with nothing on NAND and be able
to flash anything is needed(barebox, kernel, etc) by just using one
tool(MFGtools, fastboot, etc). Not 2 steps approach: to copy the NAND
first and then to do anything else by running commands/scripts
commands. This is how I do it now.
I know that using MFGtools from NXP is possible. But with
uboot booatloader. NXP says they don't support barebox.
Aside from this issue, are you aware of any method of
flashing the barebox on NAND from Linux(after the kernel was loaded
successfully on the target) ?
barebox_update does not exist in Linux obviously and porting it is not
so trivial, on top of that I don't think I am able to access the nand
device from Linux, but only MTD partitions .
I have tried nandwrite and kobs-ng commands but I was not successful.
Thanks,
Mihaita
