[ET10x00] PCTV 292e USB Tuner

[EMJB]

I am trying to get my PCTV USB tuner working, and have:

(1) Installed the dvb-usb-em28xx driver from the plugin menu

(2) Put the dvb-demod-si2168-b40-01.fw (with and without dvb-demod-si2168-02.fw) file(s) in /lib/firmware from https://github.com/OpenELEC/dvb-firmware/tree/master/firmware in /lib/firmware

dmesg indicates that it has been recognised including:

em28178 #0: Identified as PCTV tripleStick (292e) (card=94)
[ 12.805000] em28178 #0: dvb set to isoc mode.
[ 12.810000] usbcore: registered new interface driver em28xx
[ 12.834000] em28178 #0: Binding DVB extension
[ 12.853000] em28xx: Registered (Em28xx dvb Extension) extension

with no suggestion of an error. However It still does not appear in the list of tuners.

Elsewhere I have seen references to needing to enable I2C support in the kernel - if this is required could some-one please explain in simple terms what I need to do. If this is not the problem, any help would be much appreciated.

TIA,

EMJB

Elsewhere I have seen references to needing to enable I2C support in the kernel

I got mine working on an Xtrend et8000 (before the OE-Alliance knackered the kernel and refused to revert to a working one).

FYI: pctv Triplestick (292e)

I now have an Xtrend et8000, running a 4.0.1 kernel so decided to see what happened if I plugged a pctv tripleStick (the 292e) in to USB, as I happened to have one lying around.
It was recognized.
Then I installed firmware-dvb-fe-si2168, kernel-module-si2157, kernel-module-si2168 and kernel-module-si2ixx (the latter just because it might match - it doesn't seem to be needed). This has to be done from the command line as there is no enigma2-plugins-* wrapper for them to show up in the downloads menu.
It works.
I now have 4xDVB-T2 tuners and have tested that I can record on 4 separate muxes (and only get "Tuner failed" on trying a fifth).

[It doesn't seem to play ball with the signal finder menu (just flips around at ~35dB rather than reporting any expected figures).]​

Unfortunately that seems to lead to a lock-up of some sort during booting , with the following at the end of the dmesg report:

An SSH reboot command had no effect, so the only way of moving forward was switching off the power.

Just in case I had messed things up with my earlier efforts, I removed the USB tuner & re-installed 5.0.009 without re-installing previous plugins, and then:

(1) Installed the driver using the sequence : Main menu -> Plugins -> Green to download plugins -> Drivers -> dvb-usb-em28xx ->Ok

(2) Using Putty, I then installed the three files you mention with the commands:

opkg install kernel-module-si2157
opkg install kernel-module-si2168
opkg install firmware-dvb-fe-si2168

(3) Switched to deep standby, plugged in the USB tuner, and restarted to get stuck in the booting process as above.

(4) Rebooting without the USB tuner plugged in worked OK.

(5) Installing kernel-module-si21xx and rebooting with the USB tuner installed gave the slightly different dmesg report:

Any help would be much appreciated.

Further to my previous post, when it locks up the main log files ends with:

with the last two lines repeated ad infinitum at 2 second intervals. Does this help establish what is going wrong?

Your usb tuner problem may well be related the SundTek tuner problem I reported a couple of months ago, here is the last post....

http://www.world-of-satellite.com/s...ith-USB-tuners&p=445035&viewfull=1#post445035

N.B.

I got mine working on an Xtrend et8000 (before the OE-Alliance knackered the kernel and refused to revert to a working one).

 

[birdman]

It is. This is the same problem as is seen on the Xtrend 4.8.3 kernels. Indeed - it's just occurred to me that the et10x00 is built with the same kernel as my et8000 - I hadn't noticed the box model.
