Hi all,
I just started using barebox on the iMX35 PDK and I have a bit of a problem.
My actual board is based on the PDK but with a slight change: the NAND chip is of newer generation and
has 4k page and 218 oob area.
I need to add support to boot from 4k pages in barebox and I can't seem to find any documentation on how to do that.
Can anyone point me in the right direction as to where to find this in the barebox code?
Thanks,
Boaz.

check in drivers/mtd/nand/nand_imx.c

Hi Eric,
Thanks for the quick response, what I would like to know is where is the actual entry point to the code,
i.e. the "main()" function...
I'm asking this because when I try to boot barebox on my board with the different NAND I don't even get a prompt on
the serial line so I figured the image is not read properly.
Thanks,
Boaz.

check in this file, the imx_nand_load_image function where only 512 & 2k nand
are handled.
Are you using internal or external boot ?

so you have to update this function to your hardware (ie : to add 4k page
support in the nand driver).
