Seagate BlackArmor NAS 220

Well,that wont work.
Image specific to NAS220 is needed

Yes, it didn't work :frowning:
I changed UBFS_OPTS as I did with goflexhome, and the image booted just fine. Unfortunately ethernet didn't work.

The only problem seems to be the ethernet module - which seems to be built-in in the kernel. I can compile my own uimage, but I don't know that to change in order to get the ethernet working.

Well,you cant just go flashing images for other devices.
Partition layout is most likely wrong,you can easily mess up bootloader and then you are in world of pain.
Whole DTS and accompanying stuff needs to be specific for that device.

I can look into GPL to see what they used for ethernet.
But,can you give me full dmesg output?

Of course:

This is u-boot env setting needed to boot properly (also contains the partition layout):

bootargs=console=ttyS0,115200 mtdparts=orion_nand:0xa0000@0x0(uboot),0x010000@0xa0000(env),0x500000@0xc0000(uimage),0x1a40000@0x5c0000(rootfs) ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs

I didnt mean from Iomega image,but from stock firmware

The original firmware wasn't loading at all - the hard disks were crashed and someone (as far as I know) did a firmware upgrade which didn't go well.

I followed this https://wiki.ccc-ffm.de/projekte:diverses:seagate_blackarmor_nas_220_debian
to compile / reflash an up-to-date u-boot.
I guess I could go with debian, but lede/openwrt is much faster/smaller

Well,I just now figured out that NAS220 is actually upstream supported and kernel already has DTS for it
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/arch/arm/boot/dts/kirkwood-blackarmor-nas220.dts?h=v4.14.48

But there is no NAND or SPI NOR defined.
What kind of onboard storage does it have?

I am sure it has a 32 MB nand chip - I can verify the exact part number tomorrow. The default partition scheme from u-boot (2018.05) works perfectly in my setup.

I am more than willing to devtest a new image if you can help me out setting the toolchain. eg: where does this dts file shall go?

If u-boot scheme works that can be used.
DTS is already in the kernel,it just has to be patched to include partition layout.

I can try to patch it in the evening.
But you gotta confirm what onboard storage it has
Its not hard to build from sources,there is a lot of documentation but biggest part is simply installing required packages

I am 100% sure it is nand and it has only 32MB.

If you need exact part number, I can find it tomorrow

No need,I patched in the partition layout you used above.
Just that I merged kernel and rootfs into ubi so OpenWrt can auto resize them as needed.
Added profile for it into OpenWrt as well as needed packages.

Its built:

Give initramfs a test

Maybe Arch is what youre seeking.

You ARE amazing. The initramfs worked like a charm, it booted and enabled eth0 at 1gbit:

You also included luci!!! Unfortunately though, both sysupgrade and factory images were not recognized...

So far I was directly writing into nand the kernel and root files from sysupgrade.tar.gz files, how can I "install" what you've sent me ?

Hm,sysupgrade should work from initramfs.
Whats the error you get when trying to sysupgrade?

first of all - it cannot confirm it:

root@OpenWrt:/tmp# sysupgrade -v /tmp/sysupgrade.bin
Device seagate,blackarmor-nas220 not supported by this image
Supported devices: seagate,nas220 blackarmor-nas220
Image check 'fwtool_check_image' failed.

...then I used -F switch to force it:

root@OpenWrt:/tmp# sysupgrade -F -v /tmp/sysupgrade.bin
Device seagate,blackarmor-nas220 not supported by this image
Supported devices: seagate,nas220 blackarmor-nas220
Image check 'fwtool_check_image' failed but --force given - will update anyway!
Cannot save config while running from ramdisk.
Commencing upgrade. All shell sessions will be closed now.

Is it necessary to go with ubi? The only reason I used it was because I wanted to give a try to 15.05 images.

Ok, so sysupgrade is not working due to supported devices being set wrongly.
Hm, something weird is happening so kernel cant mount rootfs.

Why not go with UBI?
Hardcoding kernel and rootfs partitions is not good way to go,and those two ubi partitions are kernel and second one rootfs.

I will fix supported string,and it should work

When I was cooking images with imagebuilder, I had to modify

GOFLEXHOME_UBIFS_OPTS:="-m 512 -e 15872 -c 4096"

in /target/linux/kirkwood/profiles/110-nas.mk

in order to get a mountable ubifs image...

Hm,UBIFS_OPTS were removed a while ago
https://github.com/robimarko/openwrt/commit/d2e18dae2892b5779226b75d49aa7e6078835ffe#diff-4121fe41a24f88d321e87913c58a099b

Yes, I used 'em for 15.05 version

Hm,well I think we can introduce it for just this device
Will make new images in the evening
