at91sam9260-ek ...

[Vanhauwaert Wouter]

Hello,

Is the setup for a at91sam9260-ek still functioning?
I have troubles with my nand flash. At first it boots and writes BBT-tables.
However, next boot, it won't read the BBT, and has errors with the magic on the environment variables.
Erase /dev/env0 and saveenv do not make a difference.
Nandtest does not give me errors...

I'm just using the latest barebox 2014.2 and loading it on a at91sam9260-ek through usb (sam-ba). I'm just using the plain at91sam9260ek_defconfig

My output:

Seems there's something broken. I have no better idea other than
bisecting it.

Is there a version which is definitely working and tested with at91sam9260-ek?

I'd probably start at somewhere near:

ecdb717 at91/boards: switch to software ecc as in linux kernel

But I don't know if that version really works.

(If you don't know already, you can always start barebox second stage
from an already running barebox, normally you shouldn't have to reflash
for each bisecting step. Something like "tftp barebox.bin /dev/ram0; go
/dev/ram0" should work.)

I did some tests and seems that it worked ok until version release 2013.08.0, from 2013.09.0 on it gives me these errors...

Between 2013.09.0 and 2013.08.0 there's much changed in the mtd driver... Also in atmel_nand.c, 2 parameters (int oob_required, int page) are added to the page operations.
Although nothing is done with it. I don't know what's going on further. I'll just stick with 2013.08.0 for now, I think it'll just fit my needs. Maybe somebody who knows what's going on can take a look at it?

Grtz,

It would be great if you could find the initial point of this bug
by using git-bisect, as Sascha says.
We could help in using this tool if you have trouble.
