Ib-nas6220-b

Hi EB,

I'm noob here.
Is there any discussion about IB NAS6220 openfirmware development? Can I help to develop firmware for it?
As I see the drivers are in vanilla kernel. I hacked the root login on my NAS successfully so I can login as root into it.
I found a Fedora 12 ARM repo at ftp://ftp.linux.org.uk/pub/linux/arm/fedora/ so I can install packages from this mirror.

Cheers,
oreggin

hey ... good work ...
Maybe it is possible to enable GPT http://en.wikipedia.org/wiki/GUID_Partition_Table

They are only a few changes need in some rpm archive and maybe a new kernel is needed.

I use Gentoo on my NAS4220 and now I want to install onto this new powerful NAS6220 but I haven't console access as I don't know where is the console port on the PCB.
New kernel is needed as GPT support isn't in the original kernel:

Code:

[root@isharing ~]# zless /proc/config.gz | grep -i parti
CONFIG_MTD_PARTITIONS=y
# Partition Types
# CONFIG_PARTITION_ADVANCED is not set
CONFIG_MSDOS_PARTITION=y
[root@isharing ~]#

The root login can be activated if you log in to the NAS as admin on the WebUI and then change the username on the browser's addressline from admin to root and press enter and you see that the user name is changed on the webpage. Then go to the password change option, change the root password and voila you can login as root over SSH.
Now I can dump the MTD partitions and anything as I want

Gentoo, nice ..... You are very welcome ...

For serial console I'm working on, I have some nice photos of the PCB.
Maybe I found the port, but I need new Cable ...

Yeah Gentoo, as Debian dropped ARMv4 support from squeeze. Remained solution is Gentoo with distcc.

I think, the serial port is on the PCB back 2x10 copper contact?

I think not.

You will see another 4-pin header around the postion of the hdd power supply.
They are 3 4-pin headers.
2 with same size, for hdd power supply. (lead pitch 2.54mm)
and a smaller one (lead pitch 2mm)

These headers are hidden by the wire for front panel

2x10 looks like JTAG for me.

OH. BTW.
I think armv4 was not in Debian maybe in very old ones.
armv4lt ( I hope I remember this type) is the smalles arm cpu for DEBIAN, because newer DEBIAN will support only EABI.

Ok, I see. It have different color on my PCB.

I ain't an ARM prof but yes

I know Debian lenny run on FA526 what called the vendor "fully ARM9 compliant" but they missed to mention that Thumb instruction set is missing from their SoC's CPU so I can't use "-mcpu=arm9" CFLAGS as Debina squeeze too. In Debian lenny and before the kernel and binaries are compiled for armv4l without Thumb and OABI.

**ElektromAn** · 03.04.2011, 16:33

For EABI and -mcpu and other options read here http://wiki.debian.org/ArmEabiPort
Gentoo links to this site too.

Tomorrow I will buy me some connectors, hopefully they have some with 2mm lead pitch.
