tanya,

If the Intel Pro NextGen is the one you're looking for, then check your modules see if it is running

lsmod | grep -i iwlwifi

Hello,

Which dtb/dts is the best for 310S 3.18.5 kernel (compiled by my self with your 3.18.5 patch) at the moment with stock u-boot?
I tried from 3.18.5, 4.1.0, 4.2.0 for 310S, 320S and encountered a problem with ethernet (not from u-boot - I don't need it).
After some reboots, coldboots nas can't get access to network. There is also problem with power button (not working).

The 3.18.5 patch does not have ethernet PHY problem patch file.

It's best to use the latest released kernel for NSA310S, and the kirkwood-nsa310s.dtb. The ethernet link problem has been fixed in the latest kernel. To verify, you should install the latest kernel release and see if it works consistently and go from there.

Typo here:

should be

usb_root=/dev/sda1

is the command fw_setenv usb_root=/dev/sda1?
Got it fw_setenv usb_root '/dev/sda1'

archat68,

fw_setenv usb_root '/dev/sda1'

It is good practice to always wrap the entire value string in single quotes (in the above command, there is no need to do that). But it is required when there is special character in the stringg. For example, spaces in usb_scan_list:

fw_setenv usb_scan_list '1 2 3 4'

Thanks!!
I booted through the USB stick with 3.16 rootfs. I have provided a SWAP in USB stick (400MB) with unallocated space of 400MB .
I shall do a apt-get update followed by upgrade.

i) Next to upgrade to latest kernel what shall I do?

ii) What I want to do is to boot through the USB stick with the HDD attached to the dockstar. I do not want to make any change in the filesystem of the HDD now and want to use as storage directory so that in case of any trouble I can use my HDD and boot into earlier version. Is it possible since both the disks have rootfs installed and are bootable?

I already have a SWAP in HDD. Can I use that when booting from USB?

iii) Also can I resize the partition of the HDD - install the 3.16 rootfs in a new partion and keep other partition intact and boot with it?

First post of this thread, the instruction is in section Updated 30 June 2015. Same instruction applies to all newer kernel releases.

You can do all this. See this thread: http://forum.doozan.com/read.php?3,19093

And post questions if you're not sure about something.

Thanks it's seems to be ok. I think last problem concerns not working power button, I can't do shutdown by pressing him.
I know it's a trifle, but is there any solution?

The Power button needs to be set up, since the kernel is Kirkwood-wide so does not have such specific box set up. Besides, this really belongs in rootfs, not kernel. The kernel only provides the buttons capability as GPIO button.

See DavideDg writeup for Esekeyd. It is a little bit cryptic, since Davide posted what his setup looks like, there is no instruction. If you have problem setting it up, I'll post mine with more comments.

And look at your dmesg to see if the that network is up.

Check it to see wlan0 is active (bring it up is a separate command)

ifconfig -a

And do you have it set up to bring the wifi network up?

Isn't this a bit off-topic ?

@tanya,

You probably need to install firmware-iwlwifi package. And davidedg is right! please start a separate Debian topic for this wifi card problem. The module is included in the kernel, so there might be some more set up is needed.

Hello bodhi. First of all thank you very very much for this great work.

My NSA320 now runs your Deb8 image with 4.2.0-kirkwood-tld-1, booted with DTB from a USB drive.
Uboot is u-boot-2014.07-tld-4

I have a small(ish) issue, counts more towards comfort then a real issue, but it would be great if it can be fixed.
The kernel throws alot of bad eraseblock errors at boot, as you can see from the dmesg excerpt bellow.
In Debian, when issuing any nand/uboot related command I also get badblock messages and it fails. My main problem is that I have to reboot in uboot and break boot to edit the env. Also flashing new uboot is a bit more cumbersome.

In uboot, however, I can read, dump, erase, write the nand no problems. No badblocks appear when working on the nand via uboot.

Any advice would be really appreciated. Many thanks.

See bellow the dmesg errors attached, fw_* error and my uboot env (which is broken in 2 parts, one on nand and one loaded at boot from USB flash):

root@fs:~# fw_printenv
Too few good blocks within range

uboot env:

preboot=setenv stderr serial; setenv stdin serial; setenv stdout serial; setenv baudrate 115200; setenv console ttyS0,115200; setenv bootdelay 10

baudrate=115200

This is an easy problem to fix (we've solved it long ago in general for Kirkwood boxes). But I am wondering why nobody has reported this before on the NSA320? could be a different NAND chip is used in your NS320??

Let me take a look and upload a newer DTB for you to try.

thank you for your reply.
I replaced the factory nand some time ago as it was reporting a bad block at very low offset (in the uboot area), so I swapped it out for an identical chip and recovered the box with kwboot.

Can't say if the factory nand would report the same errors as the replacement, as I never had anything but stock fw on it. Also, reswapping them is not such an easy job, the pin pitch is quite fine.

I believe I did not have this issue on the non-FDT kernels. But I'm not sure. Maybe I'll give it a try now if I find a free USB drive.

Ah! this is what I think to be the cause. I'm pretty sure that I had a correct NAND chip delay in kerne 3.16.x. So the fix is most likely that the device tree needs to conform to the old setting.

vcheche,

Please try this DTB.

Bad block errors are gone and I can now read and write to the uboot env from Linux.
I will also try an uboot flash with nandwrite, but I think it will work just fine.

Thank you very much,
Val.
