22.03.3 compile including drivers for usb DVB sticks

For Developers
1

I compiled OpenWrt 22.03.3 for Netgear D7800 in order to include kernel support for a usb DVB-T stick and a usb DVB-S receiver for the tvheadend package:
https://www.linuxtv.org/wiki/index.php/ITE_IT9135
https://www.linuxtv.org/wiki/index.php/DVBSKY_S960

I copied the related firmware files in files/lib/firmware before compiling

dvb-demod-m88ds3103.fw
dvb-usb-it9135-02.fw

I selected the two devices in kernel_menuconfig and compilation ends with no errors, but after installing sysupgrade, none of the two sticks get recognized. Logread just states:

usb 3-1: new high-speed USB device number 2 using xhci-hcd
No mention about loading firmware.

What did I miss?

list of installed packages
build log
.config
syslog
kernel log

Note:
I had to comment out the row about fastmirrors.org in feeds/packages/utils/rrdtool1/Makefile
cause it hung downloading non existing files.

Sorry Lucky1, I don't get what that means. I have no practice on compiling but I already compiled 22.03.3 with support for those two receivers for a Buffalo Wzr600-dhp2 and a Linksys 1900acs (only DVB-T on 22.03.0-rc6 for that one) and it worked flawlessly.
They get recognized and initialized at boot:

Now why is that they don't get recognized on a Netgear D7800? First thing I thought was some missing package but I can't find which one, or maybe a hardware problem. I tried using an active USB hub in case the ports could not supply enough power but the result was the same.
And if I connect an hdd it gets recognized and mounted..

now a read it better
I think there is a kernel switch need to make it work
but it's not selected in the main stream versions
so you have to compile it your self
until the above pull request goes through anyway

so you will have to recompile the new version with the same alterations you made last time

5

I don't know where to start about that, maybe I'd better wait.
Anyway there's no selectable package
kmod-multimedia dvb-core dvb-usb-v2

in make_menuconfig

6

well it need more people test & support
and take interest in the pull request above
if it gets passed you would not need this topic

7

Is this interesting D7800 only? I compiled for the Buffalo and Linksys some time ago and I didn't have this problem.
I would test this myself but I don't know if I'm up to the task.

8

if you get motivated to try it and build it

rm -rf dvb
git clone https://github.com/M95D/openwrt.git dvb
cd dvb

git fetch --tags
git checkout m95d-dvb

./scripts/feeds update -a
./scripts/feeds install -a

make menuconfig
9

Well, that seems simple enough, thanks, I'll try.

Sorry about the dumb question.. there are several dvb folders in openwrt directory, I assume I should replace one of them but which one?

I have only used one that already in there so I don't know about adding more

Ok, OpenWrt 22.03.4 is out so I decided to delete everything and start from scratch.
Compile went well and the two tuners seem to be recognized

Problem is now there's something wrong in tvheadend menu. Configuration and status tabs are missing so the wizard can't be started. Any idea why?

Hello all , how can I compile with branch v24.10.0. I compile but with OpenWrt SNAPSHOT r28740 and kernel : 6.6.74 work good but prefer stable image.Use Astrometa DVB-c on BPI-r3.
Than you!!!
PS
I use https://github.com/tmn505/openwrt-dvb for compile in SDK , work very good with kernel 5.x.x but is not update to kernel 6.6 and i have error on compile.

15

I don't know, it seems the patch https://github.com/openwrt/openwrt/pull/12210
as it's not open any more
seem lie maybe people did support it enough and had fallen by the wayside

16

Hi @ Lucky1 thanks for fast response.Interesting that I manage to compile with the latest kernel in SNAPSHOT.I don't know if it's a bug in git or I don't know what commands to use to force compile with the stable version v24.10???
In this situation we do not have openwrt with DVB on kernel6.6 :disappointed_relieved: there is hope in @tmn505.

17

is it working in the current snapshot ?

18

Yes work correctly.
But is beta version , use apk not opkg, some kernel-module like kmod-nvme missig (I had to recompile for this module) .Ii have same package in .ipk like oscam already compile in .ipk .
In v23.05.4 BPI-R3 work perfect with DVB-c + oscam , Samba server with nvme , WIFI6 etc and BIG problem : I don't have easy access to the router as it is located in the attic of my house. :grinning:.

19

i'll have a go in the next few weeks
maybe that pull request was closed due to being needed :slight_smile:
