Hello I'm trying to build a music mpd server. I have bought a usb audio sound card..Ok
my problem is that the music is on a nfs server, but I have install nfs utils.. and when i
mount.nfs4 ip:/folder local_folder
it give me this output.
mount.nfs4: No such device

What can i do?
thx

Do you have the necessary packages?
-nfs-utils
-kmod-fs-nfs
-kmod-fs-nfs-common

This might also help: https://wiki.openwrt.org/doc/howto/nfs.client

Same here:

root@Cebola 1:~# opkg install kmod-fs-nfs kmod-fs-nfs-common
Unknown package 'kmod-fs-nfs'.
Unknown package 'kmod-fs-nfs-common'.

@Gian-Carlo-Salvati you refer to a request where was for the omega1.

On omega2 you have to check first /etc/opkg/distfeeds.conf :

and activate the LEDE Package Repo. Further info's you find here:
software-using-opkg (scroll down to the end of the document).

@Luciano-S thanks, but no progress..

What can I do?

Richard Berg · 10 Mar 2017, 04:16

Since you've done the opkg list | grep <name> already and it listed these:

nfs-kernel-server - 2.1.1-1 - Kernel NFS server support
nfs-kernel-server-utils - 2.1.1-1 - NFS server utils
nfs-utils - 2.1.1-1 - Updated mount.nfs command - allows mounting nfs4 volumes

You might see that the package name nfs-utils has the tools for mounting nfs4 volumes..

So if that's the case then do a:

opkg install nfs-utils

?

Gian Carlo Salvati · 14 Mar 2017, 22:37

@Richard-Berg thansk, but I already installed this package.

What happens is there is no kernel driver available forthis system.
Then mount command shows there is no device ..

root@Omega-8D69:~# opkg list | grep nfs

Luciano S. · 15 Mar 2017, 00:21

@Gian-Carlo-Salvati , you version is Omega2 or 2p(lus)?

If 2p I was reading that bigger than omega2p-v0.1.10-b160.bin makes trouble. Even a kernel problem was reported in one of the above ...b160.bin

Gian Carlo Salvati · 15 Mar 2017, 00:50

@Luciano-Veronese Omega2 on my tests.

Ahh OK then yeah the firmware must be compiled with those driver enabled.
Have you tried compiling the firmware? There is a post here on how to use Docker and a pre-built image that a community member has built.

I was able to compile my own firmware and saw the options to include the kernel driver AS seen in the image below. If you can get the Docker image (or other way) to compile the firmware; you could also include this kernel driver in the firmware and flash and test it.

Below is the Omega2 firmware 'make menuconfig' option showing the nfs file system kernel driver. If you want, I can try to take the defaults and add this driver in and build the firmware. I could then host it on my GitHub and you could download and try to flash it from there. Would just take me a bit of time but BE FORE WARNED that while I'm sure I could get it to compile, and have done it with other OpenWRT builds and boards; I cannot say it won't strand you but making the device unusable. All attempts at this source is to share with the community BUT you take all risks in knowing how, what to do if problems occur.

Let me know and I can compile for you with some options (if you know them) and the nfs module and you could test.
Cheers,

Gian Carlo Salvati · 15 Mar 2017, 22:43

@Richard Berg thanks! I would like if you could do it for me!
If something goes wrong there is any way to flash the original firmware?

I will read about docker option too!

thanks!
Let me know when you publish the file!

Richard Berg · 16 Mar 2017, 00:06

@Gian-Carlo-Salvati

Started to build then I remembered there are Omega2 and Omega2+.
If you have time before the build of the firmware, let me know which you want.

If I don't hear back from you before I'm done building the Omega2 (plain) I'll just spin the configuration for the Omega2+ and make you one of each, lol.

Cheers,

Richard Berg · 16 Mar 2017, 00:47

@Gian-Carlo-Salvati

Here is the github repo with 2 files: one for the Omega2 and one for the Omega2+
Choose your version, download and flash.

https://github.com/Ictinike/Omega2-firmware

BEWARE, however, that I may not be able to help you get back to default firmware if something goes wrong with the flash but I have helped someone recover their Omega2+ from constant reboot due to a bad firmware from Onion.

If we get to that point, let me know and we can help you with a dock and USB if you have them. If not, you may have to use a TTL2USB adapter and go serially. This would be NO different if you flashed a bad firmware from Onion so while I give you the BEWARE it's something you may have to do eventually, lol..

Here is the option I enabled from default firmware:

Cheers,

Gian Carlo Salvati · 16 Mar 2017, 02:08

Thanks a lot!!!
I dont know how to thank you!
I will try it!

Best regards!

Gian Carlo Salvati · 16 Mar 2017, 03:23

now it Works! I used Serial connection.
But I cant connect to wifi.
I am using this user-guide:
https://lede-project.org/docs/user-guide/wifi_configuration#startstop_wireless

Any hint?

Gian Carlo Salvati · 16 Mar 2017, 11:25

I did connect to my Wifi network, but the signal is so weak now.

I saw come configurations on this forum that points to ralink driver instead the one that came with the kernel in this firmware...
Which one is the best?

Richard Berg · 16 Mar 2017, 18:59

@Gian-Carlo-Salvati

Awesome!

As for the WiFi driver I'm not sure. I used what was packaged in the Docker image from another user. If by chance you have used Docker the image is pretty straight forward and once you build the toolchain & tools binaries (which takes me about 1 hour roughly on an 6/12 core i7 49230K @ 3.4ghz) it builds in roughly 20 mins thereafter. If not Docker, you should still be able to use Linux and pull the source but you'll have to do some configuration up-front.

I'm just glad the NFS works but again, sorry on the WiFi

Richard Berg · 16 Mar 2017, 19:02

@Gian-Carlo-Salvati

Also, below is the driver that came 'stock' setup in the firmware.. If you deduce which one you wish to try let me know and I can attempt to merge in and rebuild for you. Lastly, Omega2 or 2+ just in case we do get to rebuild it for you

Gian Carlo Salvati · 17 Mar 2017, 20:37

@Richard-Berg thanks!

I saw now on my other omega2, the default driver on original firmware is: ralink_eeprom_api , mt76x8, ralink_gdma.
On /etc/config/wireless the configuration for wifi device is: 'ralink'

I don't know, but I will test more then I tell you.

Thanks in advance!
