Flashing kernel from Linux

Flashing kernel from Linux

[Patrick Gerber]

Dear mailing list

I used to flash the linux kernel using barebox update command.
Now I would like to do the same from the Linux side. A simple dd to 
/dev/mtdblockX used to work with uboot but doesn't work with barebox. 
Barebox complain at startup about bad image...
Do you have any hint about how to flash the kernel from the Linux side ?

Thanks in advance

Patrick

You first need to erase the flash (using flash_erase from the mtd-utils)
and then you might need to use nandwrite to actually write the image.

IIRC Busybox contains these utilities, too.
