Hello,

I tried to use barebox in order to boot from NAND.

The ROM loader needs a FCB (Firmware Configuration Block) table at the 
beginning of the flash (according to chapter 7.5.2.2 of the reference 
manual).
I looked at the existing imx53 boards within the barebox sources but I 
founx that no one used this mode there.

Has someone done this or can give me some advice?

Hi,

For a quick start you can use the provided FCB (fcb.bin).
This FCB was generated with the attached tool (fcbgen.c) - note that the bad block handling is disabled.

Then you can "merge" your barebox image with the FCB with something like:
cat fcb.bin barebox-image > barebox-fcb.bin

This works at least on our custom i.MX53 hardware.

Hello,

I have some problems. May you please send me a binary produced with this 
tool?
I want to inspect the flash header.

We have the "bcb" command recently, and the functionality should be
integrated there.

fcb.bin contains a FCB and was generated by this tool. It should instantly work with your i.mx53 barebox.
Note that the FCB image must reside within the first blocks of the NAND. The internal ROM loader will always read 4k blocks from NAND - independent of the actual NAND page size. 
The attached FCB must be located at the start of the NAND. The barebox image must be located at page 2.
Assuming a 2k page NAND you should have this:  page 0-1: 4k FCB, page 2-n: barebox.

Where can i find this bcb command? in the menuconfig, or is there a tool?
