Error "scan no data, failed" with an August T210v2 (Geniatech T230) USB stick

Added by Gordon Bissell over 8 years ago

I've built TVHeadend on a Raspberry Pi3 (running Raspian Jessie), and downloaded what I understand to be the right firmware images as per the details on http://www.linuxtv.org/wiki/index.php/Geniatech_T230#Firmware

On running TVHeadend I see the device, and have added my local mux (Oxford, UK). I have a good aerial signal (tuning a TV with the cable reports a strong signal).

Unfortunately, attempting to scan for channels always fails. The log information reports:

...

I'm unsure of how to proceed from here (I've added screenshots of the muxes, networks and TV adapters) and would greatly appreciate any help.

BTW The "auto" setting for character set on one mux was me experimenting with a suggested fix (it didn't work).

Check you're using the correct firmware (dmesg | grep si21), version 4.0.19 is known to cause the August T210v2 to fail!

Use 4.0.11 instead from here: http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.11

OK... so... that's really embarrassing. The image you've linked above is about 1/10th of the size of the firmware files I'd got - which seems a bit odd.

Turns out, if you go to this page https://github.com/OpenELEC/dvb-firmware/tree/master/firmware then right click on a .fw link and save it (or wget via a CLI, which is what I suspect I did originally), you don't get the .fw file - you get the github web page for that file. As such, I'd got two .fw files in the right directory, but they most certainly didn't contain firmware

Having now got the right files, it unsurprisingly has found all the channels.

Many thanks!

Haha, you'd be surprised at how many times people get caught out by that, myself included. Always use the "raw" links when downloading certain files from github.

But glad to hear you got it working in the end
