Linux Kernel 4.4.79 Oxnas (OX820) Pogo V3 package and Debian rootfs

Posted by bodhi 
Thanks, bodhi! I'll try it asap!
Update:
3G seems to work (can't test it more currently):

But it seems after a bit more testing that wifi didn't work at all: I can't scan nearby wifi networks with the wifi adapter attached. (Its weird that I can ping the ip address of the wireless adapter from another machine of the network; maybe it is working or the wireless address gets tunneled through wired network somehow).

It seems the adapter doesnt even support scanning:
iwlist wlan0 scan
wlan0     Interface doesn't support scanning.

Relevant dmesg:

Also interesting:

iw wlan0 scan
The issue must be somewhere else.

As requested by a forum member, attached is the patch for kernel linux-oxnas-3.14-tld-5.

Note that it is almost the same as kref's patch in GitHub. The only change in this patch is the LED is set to green explicitly when the kernel has booted.

Dear Bodhi, first of all i would like to thank you for all your work. Your U-BOOT and your kernel gave a new life to my abandoned Pogoplug Pro. I even managed to get the my.pogoplug.com service working after updating to your latest 3.16.0 kernel!
I also tried to setup Pogoplug Pro as a surveillance system with a Logitech C310 webvcam attached along with mjpeg-streamer with no success though. The thing is that because the /media/video kernel modules aren't included with the kernel, the webcam isn't initiated and found under /dev/video0 as it should, but is rather seen only as a USB device (checked with lsusb). Referring to kernel 2.6, this guide http://armbedded.eu/node/415 points out the needed modules for the web cam to work. Could you please be kind enough to provide instructions how to compile kernel source along with our oxnas kernel patch in order to be able to compile the kernel modules?

@bodhi

Hi,

I see you did some awesome work for the pogoplug oxnas devices.

I'm running an "old" eTrayz nas (by xTreamer), which is an oxnas810 device. I have been looking into ways to upgrade the kernel as it runs an old 2.6.24.4 kernel but could not find the proper source tree containing the oxnas810 patches for building a 3.0 and up kernel version, as Oxford technology kept sources to themselves.

I'm now running debian squeeze on the device using a kernel v.2.6.24.4 I build from the original source tree, crosscompiled using emdebian toolchain and it is loaded from an usb stick not by booting because the old uboot on the device doesn't support usb, but by a kernel reload. It works!

Would it be possible to adapt the PogoV3 kernel 3.16.0 package in such a way that it would also support oxnas810 eTrayz devices or could you explain where to find a kernel v3.16.0 source tree containing support for oxnas810 (eTrayz) devices ?

I also tried to update uBoot to include usb support, but was not able to find sources for oxnas810 (eTrayz) either.

Your comments/ideas would be highly appreciated.

rgds.

The ox810 and plx oxnas 8720 are different enough that they are not compatible. You will need to make the necessary forward ports.

Forward ports ? Based on what... non existing sources or non-disclosed hw specs ?
Any other ideas ?

I think what WarheadsSE was trying to say is:
There ARE indeed kernel sources for OX810. They are quite old, but they exist. So your approach would be to take those sources and port them to newer kernel versions. Maybe 2.6.32 or something like that first and maybe later newer kernels.

The point is:
If there are no newer sources and nobody else is interested enough, you'll have to do the necessary work yourself.

As WarheadsSE said, you can't expect poeple who worked on OX820 sources, to automatically provide OX810 sources, too. It's not that easy.

If you absolutely cannot live with the older kernel(s), then maybe you should consider abandoning the OX810 platform. Sounds hard, but is just realistic.

And now maybe BTT?

September 24, 2014 06:18PM
Sorry for OT cont...
I know old oxnas810 kernel sources exist, I compiled my own kernel using them, if you read my post.
Not expecting anything but some help. There are many other devices using the oxnas810 soc and and a newer kernel from such a device maybe could be used hence my question here.

@denexo,

The patch is provided in the tarball. All you need to do is to download the 3.16 source from the kernel source tree, apply the patch and build. Or you could choose to clone kref's Git, and build.

EDIT: corrected info.

intrax,

Among us, WarheadsSE is the expert for this SoC family.

You could save sometime by starting with my Git or kref's Git. And port the settings from the stock 2.6.24.4. The advantage is the drivers for USB and SATA might be OK unchanged. IMO, the most important thing to look at porting is the DTS. Chance is that if you can create a DTS for OX810 then you've completed a big portion of the porting effort. The kernel setup code is simpler because it can be based from the OX820 setup.

Also, ingmar has done a great job here with the Buffalo Linkstation (Kirkwood):

@bodhi,

thanks very much for the guidance! Will try and revert with results.
The OXNAS 8720 series uses the same SATA PHY block as the ox810 because they both use a separate piece of silicon on die, but that's about where it ends.

@bodhi,

i downloaded the 3.16 linux kernel, patched it with your patch, copied the Module.symver after installing the headers .deb, copied your config after renaming it to .config and run menuconfig. I enabled all the needed modules in Device Drivers and did a "make m=drivers/i2c" for starters. I try to insmod the module but i get the following error:
Error: could not insert module drivers/i2c/i2c-core.ko: Unknown symbol in module
When i check with dmesg i get the following info:
[83281.063731] i2c_core: Unknown symbol __i2c_board_list (err 0)
[83281.069565] i2c_core: Unknown symbol __i2c_first_dynamic_bus_num (err 0)
[83281.076367] i2c_core: Unknown symbol __i2c_board_lock (err 0)
It is important to load i2c-core.ko in order to meet the dependencies for the other needed modules. A bit of searching drove me to the openwrt forum where they state that someone has to recompile the whole kernel for i2c core to work, instead of just compiling the module after the kernel has been built. Any ideas?

@denexo,

Did you try to compile the whole thing like they did? if you'd like, post the diff of your .config and my .config and I can try compiling it.

bodhi, I have a similar question... I've got one of those generic C-Media USB DSPs that seem to be "all the rage" at the moment and I'm trying to get it to work with the Pogo Pro using your 3.16.0 kernel.. I've downloaded the mainline sources to 3.16, applied your patch, and did all the relevant including of sound support during "make menuconfig" but the kernel modules never seem to populate despite compiling through make/make modules/make modules_install

Is there something obvious I'm missing? I won't discount it as its been a good 15 years since I've complied a kernel and the alsa documentation for 3.x kernels seems to be painfully nonexistent.

All PFM to me..

Thanks.

@zer0 and others,

Would be better if you recompile the whole kernel from scratch after
make distclean

This kernel config is no where near what we have in the kirkwood kernel. I've started with kref's config so it only contains a limited set of supported devices. It does need more work to add what we already have in that kirkwood config.

I could try building the next version with all the necessary configs for devices that you guys need, in general (e.g. sound, i2c, wireless, 3G,…). But if you can post info for the devices and if you know the config names or module names then it's even better. It is difficult to troubleshoot or guess the problem with kernel compilation without trying the same thing.

Regarding the wifi problems: wext drivers are not enabled in this kernel. tools like iwconfig don't work. Perhaps also not old wpa_supplicant versions without nl80211 support.

I compiled my own kernel for this, which was very straightforward, before that I also flashed the new u-boot. Then I cross-compiled 3.16, for this I used https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.16.3.tar.gz with the patch and .config from here, I added some modules in menuconfig e.g. legacy wireless to make wext work, alsa drivers, and other stuff I personally need.
Then I rsynced the new modules folder to /lib (I didn't have to overwrite the old folder, cause this is 3.16.3 whereas the old one was 3.16.0.), I backed up the old kernel and copied over the new one. reboot without any problems, even u-boot's netconsole worked straight away in case something would have gone wrong...
Then all that was left was upgrading to wheezy with apt-get dist-upgrade. After this all wpa_supplicant worked with 3 different wifi sticks I tested. In the end I didn't test wpa_supplicant with wext though, I only used nl80211 which worked stable enough.

Thanks a lot for this very accessible and up-to-date patch!
Hey bodhi- tried that with the same result - nothing sound realted gets generated installed under /lib/modules/3.16.0-oxnas-tld-1/kernel - in comparison my sun4i (cubie) board has a /lib/modules/3.16.0-oxnas-tld-1/kernel/sound with the alsa modules (and I'm pretty sure raspbian has the same as c-media devices are supported in their installation).

The USB DSP de jour seems to be this guy:

http://www.amazon.com/HDE-Channel-External-Sound-Adapter/dp/B0027EMHM6/ref=sr_1_7?ie=UTF8&qid=1411826920&sr=8-7&keywords=usb+audio

...which shows up as:

Bus 001 Device 003: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter

...and is based off the CM106 chipset - there are literally hundreds of variants and clones of this device so it is pretty widely used.

Not sure what alsa module that ends up using, as alsa's documentation makes me want to kick a puppy.

Thanks!

@zer0 & denexo,

I'll give it a shot! will rebuild it to see if it helps.

@ nixOS,

It would be helpful if you can post the diff between my .config and your final one. It'll be easier for others who are looking for the same thing, if it is incorporated to the released kernel.

@bodhi,

i still didn't manage to load the needed modules for the camera. Though i managed to surpass the error regarding the i2c. I attach the diff file from your 3.16.0-3 config and mine, after making all the configurations needed for uvc to work.
In order to make the camera work ones has to load the following modules with the exact order as written: v4l2-core/videodev.ko , v4l2-core/v4l2-common.ko, v4l2-core/videobuf2-core.ko , usb/uvc/uvcvideo.ko . First two modules are loaded ok, but as soon as i try to insmod the videobuf2-core.ko i get the following error

Error: could not insert module drivers/media/v4l2-core/videobuf2-core.ko: Unknown symbol in module

and this is what dmesg shows

[ 5032.813504] videobuf2_core: Unknown symbol dma_buf_get (err 0)
[ 5032.819333] videobuf2_core: Unknown symbol dma_buf_put (err 0)
[ 5032.825200] videobuf2_core: Unknown symbol dma_buf_fd (err 0)

During the build of the v4l modules, i also got the following warnings which are related to the above error message

WARNING: "dma_buf_vmap" [drivers/media/v4l2-core/videobuf2-vmalloc.ko] undefined!
WARNING: "dma_buf_vunmap" [drivers/media/v4l2-core/videobuf2-vmalloc.ko] undefined!
WARNING: "dma_buf_fd" [drivers/media/v4l2-core/videobuf2-core.ko] undefined!
WARNING: "dma_buf_get" [drivers/media/v4l2-core/videobuf2-core.ko] undefined!
WARNING: "dma_buf_put" [drivers/media/v4l2-core/videobuf2-core.ko] undefined!

I am out of ideas. I don't know if the change at CONFIG_DMA_SHARED_BUFFER from unset to y (automatically changed from menuconfg) cause the errors.
