Ib-nas6220-b

[oreggin]

Hello again

what i would like to win is :

1) an non dependable nas on any portal (i.e. myisharing or myakitio)
2) an easy upgradable way to a non official firmware open wrt or stuff (without jtag stuff,serial conection) for noobs like me
3) an easy way to have full access on my nas unit through ssh also for replacing mldonkey with transmission client.

I have found out several forums and git hubs regarding modification of this NAS device but sadly they are all made with jtag or serial connections.

I don't think I understand your quetion but:
If you can upgrade original firmware to etc. archlinuxarm or sg. similar without serial console than U are GOD :-)
After you change the OS on NAS than you can simply upgrade it with "pacman -Syu" or "aptitude upgrade" and the kernel will loadable from HDD or USB stick or from NAND. I use the NAND method, made UBIFS for root with zlib compression to fit archlinuxarm on them. ArchlinuxARM provide uImage kernel binary what I can simply write to /dev/mtd1 with mtd-utils or with "/bin/cat /boot/uImage > /dev/mtd1" command. Unfortunately old u-boot loader cause L2 cache disable with newer Linux kernels (3.2+), so on ArchlinuxARM still 3.1.10 kernel version is.
If you plan to change the OS on your NAS, the preferred way is to install new OS onto the HDD or USB stick. This way keep your original firmware.

can we have a post here with "How To"?
with description and a complete guide for noobs step by step.

thank you alot

Plz don't ask the whole Larousse encyclopedia from me.

Read the whole thread especialy the #68 post: http://forum.nas-portal.org/showthre...ll=1#post56057

If you are a beginner then U should starting with debian.

I saw that u-boot is now has an initial nas62x0 support:
- http://www.mail-archive.com/u-boot@l.../msg85007.html
- http://comments.gmane.org/gmane.comp....u-boot/129493

I decided to try it but at first try I was flashed the wrong image to the NAND so my NAS6220 is bricked again. Fortunately I have an olimex arm-usb-tiny-h JTAG cable from previous bricking

Here is a description how-to use JTAG cable on kirkwood platform: http://archlinuxarm.org/forum/viewtopic.php?f=18&t=1120

You can download OpenOCD for windows from here: http://www.freddiechopin.info/pl/dow...gory/4-openocd

If you want to try it from GIT repository and make from source then make sure you flashing the u-boot.kwb image and NOT u-boot.bin:

git clone git://git.denx.de/u-boot.git
[ . . . ]
cd u-boot
make CROSS_COMPILE=armv5tel-softfloat-linux-gnueabi- ib62x0_config
[ . . . ]
make CROSS_COMPILE=armv5tel-softfloat-linux-gnueabi- u-boot.kwb
[ . . . ]

Here is my u-boot image from u-boot GIT master: http://genie.ki.iif.hu/NAS/u-boot.kwb

If you want to try it from GIT repository and make from source then make sure you flashing the u-boot.kwb image

I compiled an u-boot.kwb image, flashed it within the u-boot, but its not booting...
Is there a special address to be flashed, or should I repartition the nand, because the MTD partitioning of the patch deviates from the original?

BTW, starting an u-boot image trough the uart port is working!

See:http://www.solinno.co.uk/public/kwuartboot/

I managed to boot from an doozan kirkwood uart u-boot, but not from the self-compiled.
So I'm still missing something about compiling and flashing an denx u-boot.

[oreggin]

Which type of cross-compiler did you use to compile u-boot from source? I use gentoo and crossdev to make cross-compiler:

$ crossdev --stable -t armv5tel-softfloat-linux-gnueabi

Did you tried my u-boot.kwd image?

[argo]

I used the gcc-arm-linux-gnueabi arm softfloat crosscompiler from ubuntu 11.10, yourimage is not working as well, so I might flashing it wrong...

[oreggin]

There are two methods to flash u-boot under Linux shell:

1.:

mtd_debug erase /dev/mtd0 0 524288
cat u-boot.kwb > /dev/mtdblock0

2.:

mtd_debug erase /dev/mtd0 0 524288
mtd_debug write /dev/mtd0 0 524288 u-boot.kwb

[argo]

I was flashing from the boot loader:

usb start 
fatload usb 0:1 0x0800000 u-boot.kwb
nand erase 0x0 0x<size>
nand write 0x0800000 0x0 0x<size>
