AT91SAM9263-EK

Hello everybody,

I am trying to learn and to play with the at91sam9263-ek (Rev. B) evalboard.

I was really successful building all parts (at91Bootstrap, Barebox, Linuximage) and when I upload all files via SAM-BA and I restart the device I get the prompt of barebox.

But nothing more
Everything is fine I can also switch on and off the on board leds but I cannot load/ start the kernel.

The addresses I use are:

        0x     0000 - 0x1 FFFF at91Bootstrap
        0x  2 0000 -  0x5 FFFF Barebox
        0x  6 0000 -  0x7 FFFF Bareboxenv
        0x  8 0000 -  47 FFFF kernel
        0x48 0000 -7c7 FFFF rootfs
    and rest is data ...

I have change the specific init.c file and boot file in the specific environment folder.
First I though the missing *.bb partitions can fix this problem. Then I modified the env/init file for that. Apparently this placeholder "*" in this boot script (nand -a dev/nand0.* ) is not working correctly.
addpart /dev/nand0 $nand_parts
nand -a /dev/nand0.*

nand -a dev/nand0.at91bootstrap
nand -a dev/nand0.barebox
nand -a dev/nand0.bareboxenv
nand -a dev/nand0.kernel
nand -a dev/nand0.rootfs

The second try was to change also this partition table in the specific init.c so that both match.

        devfs_add_partition("nand0", 0x00000, SZ_128K, 
DEVFS_PARTITION_FIXED, "at91bootstrap_raw");
        dev_add_bb_dev("at91bootstrap_raw", "at91bootstrap");
        devfs_add_partition("nand0", SZ_128K, SZ_256K, 
DEVFS_PARTITION_FIXED, "self_raw");
        dev_add_bb_dev("self_raw", "self0");
        devfs_add_partition("nand0", SZ_256K + SZ_128K, SZ_128K, 
DEVFS_PARTITION_FIXED, "env_raw");
        dev_add_bb_dev("env_raw", "env0");

But everything without success. It's a little bit strange because when I execute the command
bootm -v /dev/nand0.kernel.bb
First I get the following output

        Barebox:/ bootm -v /dev/nand0.kernel.bb
            Image Name:     Linux-3.4.0
            OS:                      Linux
            Architecture:     ARM
            Type:                   Kernel Image
            Compression:    uncompressed
            Data Size:           2034784 Bytes = 1.9 MB
            Load Address:    20008000
            Entry Point:        20008000
        err -74
        loading os image failed with Out of memory

and if I try again the same command
Barebox:/ bootm -v /dev/nand0.kernel.bb
err -74
Unknown OS filetype (try -f)

also if I try to memcpy or uimage I always get this err 74.

What is this Error 74 (-- Reset level 3)?
Why Out of memory?

Kind regards

Sven

-74 is EBADMSG, see include/asm-generic/errno.h. The nand driver throws this when it can't read due to ecc errors. Something seems wrong with your nand driver. I remember Jean-Christophe mentioned that the atmel nand support is currently broken. Could you please try if either:

- barebox v2012.07.0 or
- current master

works for you?
