TBS 6902 not detected after reboot

TBS 6902 not detected after reboot

Postby Mark83827 » Thu Aug 17, 2017 6:11 pm

Hi, no response from support@tbsdtv.com for two weeks so posting here.

I have a TBS 6902 that's failing to be detected following driver compilation and reboot.

"uname -a" output:

Linux freyr 4.4.0-77-generic #98-Ubuntu SMP Wed Apr 26 08:34:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

"cat /etc/issue":

Ubuntu 16.04.3 LTS \n \l

(Actual installation is MythBuntu back-end only)

Followed the "TBS User Guide". (Copy paste bug in my PDF viewer so typed in manually)

The card is alive:

root@freyr:~/results-failure# lspci -vvv |grep 6902
Subsystem: Device 6902:0002

Found problem here:

root@freyr:~/results-failure# git clone --depth=1 https://github.com/linux_media.git -b latest ./media
Cloning into './media'...
remote: Not Found
fatal: repository 'https://github.com/linux_media.git/' not found



I then downloaded the driver by the product from your website (tbs-linux-drivers_v170330.zip)
Got it to compile but after reboot dmesg|grep frontend matched nothing

Then tried following instructions from this post by "steven":
viewtopic.php?f=183&t=10244#p37627

Same result - nothing in dmesg after reboot

Logs attached. Thanks.

Hi

Can you have a try change the PCI-E slot and connect the extra power for your TBS6902 ?
Check whether will be ok for the driver you can use this one :
#wget http://www.tbsdtv.com/download/document/linux/media_build-2017-0726.tar.bz2
# sudo rm -rf /lib/modules/`uname -r`/kernel/drivers/media/
#tar jxvf media_build-2017-0726.tar.bz2
#cd media_build
#./install.sh
#reboot

Thanks

Kind Regards

steven

I swapped the card into the other pcie slot and removed the other card I have (a usb controller card).

Then made sure the power supply was working (tested 12v) and checked it was plugged into the card.

Followed your install instructions

Card showing from lspci:
01:00.0 Multimedia controller: TBS Technologies DVB-S2 4 Tuner PCIe Card

but still no output from dmesg|grep frontend

Have attached the output from install.sh - plenty of warnings even though it completed. Perhaps some of the warnings need solving?

Nearly a week and no response. Is it time to request a refund?

That worked, then running make -j4:

/root/tbsdriver/media_build/v4l/dvb_demux.c:23:32: fatal error: linux/sched/signal.h: No such file or directory
compilation terminated.
