Hello, I'm interested in using an external tuner with my Zgemma H5 box. If it's possible, would someone please point out some information about how I can pursue it?

 

In the "External Device Support" list on the wiki, I can see "Hauppauge pctv nanoStick T2 290e (DM8000)." Should I interpret that to mean it should work on my box as well?

 

I happen to have a "Hauppauge WinTV-soloHD (DVB-T,T2,C)" that I use on a Raspberry Pi with Tvheadend:

However, when I put it into the Zgemma H5 with Openpli 6.2, it doesn't seem to be recognized at all:

[1178935.643000] usb 1-1: new high-speed USB device number 4 using ehci-brcm

While writing, I came across a post from the Tvheadend boards: https://tvheadend.or.../4/topics/29460 Apparently the kernel needs some help to recognize the id of this tuner:

modprobe em28xx card=94
echo "2040 8268" > /sys/bus/usb/drivers/em28xx/new_id

So, now it seems that the module em28xx is not in the 4.10 kernel:

#modprobe em28xx card=94

modprobe: FATAL: Module em28xx not found in directory /lib/modules/4.10.12

 

I guess that the next thing I'll look into is whether the em28xx module is in the kernel that comes with Openpli 7.0. Looks like I have a reason to upgrade my firmware.

[WanWizard]

If it comes with OpenPLi 7 you will have to install it first, we don't install anything by default that is not needed.

 

You can check with

opkg list | grep em28xx

if a kernel module exists that can be installed.

[plasticassius]

Great! It looks like it's in 6.2. I installed it with

opkg install enigma2-plugin-drivers-dvb-usb-em28xx

Then, after

modprobe em28xx card=94
echo "2040 8268" > /sys/bus/usb/drivers/em28xx/new_id

it seems that the tuner is recognized:

That seemed good, but Openpli doesn't list the tuner. Do you think it would be possible to use the external tuner along with the existing internal one?

[WanWizard]

If it works it should register itself as a tuner.

 

This doesn't look good:

[1192575.748000] em28xx 1-1:1.0: failed to pre-allocate USB transfer buffers for DVB.

[ColinB]

I see on OATV forum

 

opkg install firmware-dvb-fe-si2168

[ColinB]

More of the same from OATV

 

Installing the drivers ct2-dvb-usb-pctv292e was the crucial hint!
Now the stick is recognized as tuner C: Silicon Labs Si2168.
It can be switched between DVB-T2 and DVB-C.

Neither of these packages helped.

 

I noticed that Openpli 6.2 has kernel 4.10, and my Raspbian image has kernel 4.14. So, I have the feeling that a more recent kernel has driver fixes for this. Now I think that trying Openpli 7.0 has some logic to it since it must have a more recent kernel. (Is that true?)

[betacentauri]

We can’t change the kernel version. Manufacturer delivers drivers for specific kernel version. So we have to use this version.

[WanWizard]

I'll have a look.

I'll add firmware-dvb-fe-si2168 to develop, and see if it builds. If it does, I'll backport it to 7.0-release, after which it will be in next Monday's image.

[WanWizard]

In the meantime, what you can do is download https://github.com/o...58.zip?raw=true, and install it's contents on the box in /lib/firmware, and restart the box.

 

Please let me know if it works, so I don't do my work for nothing...

[plasticassius]

Sorry if I'm creating work for you, but of course I don't want you to do work for nothing...

 

I tried the firmware but, I'm afraid there's another problem:

I have this same problem with pctv 290e tuner in my VU+ Uno 4K SE. It works in VTI 14.0.1 image, but it has em28xx-dbv 1:4.1.20-r1.8 vti05 driver.

This is how you see pctv 290e with VTi image:

I have this same problem with pctv 290e tuner in my VU+ Uno 4K SE. It works in VTI 14.0.1 image, but it has em28xx-dbv 1:4.1.20-r1.8 vti05 driver.

 

Unfortunately that doesn't help much, VTI keeps their source closed, so we can't see what they do.

 

The em28xx driver is a kernel driver, so the kernel used dictates the version used, we build it as-is. If they added a different version, or patched it, we don't have access to it.

 

Can you check with "lsmod" what VTI has actually loaded, and then with "opkg info" what versions?

You can check with

opkg list | grep <driver>

for each of the drivers if there is a package for it, and if so, what version it is (replace "<driver>" with the name of the driver).

 

You can also check what OpenPLi loads and compare, to see if something is missing.
