storing barebox to flash /dev/nand0

storing barebox to flash /dev/nand0

[Belisko Marek]

Hi,

I'm porting barebox to mini2440 board. I can boot barebox from SDRAM
by loading to TEXT_BASE address.
I would like to test also booting from NAND flash but I can't find a
way how to store barebox loaded in RAM
to flash.

I try tftp barebox.bin /dev/nand0 but if failed with:

TFTP from server 10.146.1.21 ('barebox.bin' -> '/dev/nand0')
        offset 0x00000200 not page aligned
write: Invalid argument

tftp failed: error -22

How can I properly store to flash?

Thank's in advance,

Marek

Good news, I have this board and use a fork of u-boot from
http://repo.or.cz/w/u-boot-openmoko/mini2440.git
which is not maintained any more and it is not in mainline u-boot.

I am not familiar with barebox (I discovered it recently), but you seem
to wrongly
create your nand  image (think page size,  eraze block size, etc...)

Consider the bad blocks in your NAND. So, you will need a bad block aware 
device to write to.

This code in your board specific init routine should add the thing:

[...]
/* ----------- add some vital partitions -------- */
devfs_add_partition("nand0", 0x00000, 0x40000, PARTITION_FIXED, "self_raw");
dev_add_bb_dev("self_raw", "self0");

devfs_add_partition("nand0", 0x40000, 0x20000, PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");
[...]

(Sizes depending on the size of your boot loader binary).

And at runtime:

barebox> addpart /dev/nand0 256k(barebox)ro,128k(bareboxenv)
barebox> erase /dev/nand0.barebox.bb
barebox> tftp barebox.bin /dev/nand0.barebox.bb

you are not supposed to write directly to nand0

but to nand0.bb

tftp barebox.bin /dev/nand0.bb

after you need a barebox that boor from NAND

OK add vital partitions but after that ls -la /dev shows:

Better news ;)
I have a fork of barebox with basic support :
http://repo.or.cz/w/barebox-mini2440.git

I have some patches locally which are not in repo. I plan to push
mini2440 to mainline.

Not sure if this is all right (all show the barebox partition):

> crw-------     262144 self_raw

Okay, 256 kiB

> crw-------          0 self0

Hmm, 0?

> crw-------     262144 nand0.barebox

Okay, 256 kiB

> crw-------          0 nand0.barebox.bb

Again, 0?

For the environment it looks different:

> crw-------     131072 env_raw

> crw-------     131072 nand0.bareboxenv

All are 128 kiB.

OK maybee there is mix from mtd_parts in env config with vital partitions.
I keep just vital partitions in code but result is the same:
cr-------- 4294967295 zero
crw-------       2973 defaultenv
crw------- 4294967295 mem
crw-------  268435456 nand0
cr--------    8388608 nand_oob0
crw-------          0 ram0
crw-------         32 phy0
crw-------     262144 self_raw
crw-------          0 self0
crw-------     131072 env_raw
crw-------     131072 env0

self0 should be bb for self_raw where to store barebox. But why it has size 0?
Don't understand? Am I doing something wrong? For env it works fine.

If I understand correctly your log you have a bad block on it

You're right. I erase NAND again and then bad block for 0x00000000 is gone. I
can load barebox to flash. Sorry for spamming.
