tvheadend error: DTV_CLEAR failed [e=Bad address]

Jaanus789 · February 3, 2017 at 9:31 PM

Hi
I'm using Odroid C2 + LibreELEC-Odroid_C2.aarch64-7.90.010 .
My dvb-stick (RTL2832 + FC0013) is initialized and connected:

Also scan tool (from dvb-tools addon) finds muxes.
But tvheadend fails scanning:
[ ERROR]:linuxdvb: Realtek RTL2832 (DVB-T) : DVB-T #0 - DTV_CLEAR failed [e=Bad address]
Both tvheadends are failing, 4.0 and 4.2 (4.0.9 and 4.1.2415), addon v.102 and v8.1.109.

It works with Libreelec7 image from odroid forum:
ODROID Forum • View topic - LibreELEC 7.1.0 - media_build edition.
tvh version 4.0.9 (addon v.102 and v7.0.101).

What can be the reason?

melibokus · February 25, 2017 at 5:47 PM

Same problem with me.
Configuration: odroid c2; Realtek DVBT USB Stick; LibreELEC-Odroid_C2.aarch64-8.0.0.img.gz
(see also project örlie)
.
In sum it seems the DVB device is not correctly addressed by the involved software.
Highly speculative: Probably the deeper reason is some 32/64 bit incompatibility of the respective ioctl? function FE_GET_PROPERTY similar as described by Pavel Troller
.

Probably someone else knows more. At this point I am "at the end with my latin" (German phrase: at my wit's end

Jaanus789 · February 27, 2017 at 7:33 PM

You can try wrxtasy's media-build:
ODROID Forum • View topic - LibreELEC 8.0 - Krypton final - media build edition - 32bit
and Tvheadend 4.0 (4.2 fails for me). This combination worked for me.
If it still fails, you can first run scan or w_scan from DVB-tools addon (don't forget to uncheck "enabled" for TV adapter in Tvheadend settings before).

couchp0tato3 · March 6, 2017 at 9:07 PM

Same problem here (ODROID-C2, LE 8.0.0, RTL8283). I am not really willing to use the "media build", shouldn't 'libreelec' be literally a "medida build"...?

dabeeeenster · April 12, 2019 at 10:28 PM

Hi,

I've just received an Odroid N2, trying to get TVHeadend set up on it with the same USB stick as mentioned in this thread, and have run up against exactly the same error. Did it ever get fixed? Ive tried using TVH in docker and building by hand.

Thanks.
