Linux driver issue

Postby lwis » Fri Aug 03, 2018 2:58 pm

Hi,

I hope you can help. I'm running Raspbian stretch on a Raspberry Pi 3, here is the script I wrote to install the driver tree for my 5520SE;

Code: Select All Code
#!/bin/sh
    cd

    sudo apt install patchutils libproc-processtable-perl build-essential git raspberrypi-kernel-headers

    #sudo rpi-update 5315c7a2f806c123e9e4ee26980f0019c43b9f69

    sudo rm -rf /lib/modules/$(uname -r)/kernel/drivers/media
    sudo rm -rf /lib/modules/$(uname -r)/kernel/drivers/staging/media
    sudo rm -rf /lib/modules/$(uname -r)/extra

    wget http://www.tbsdtv.com/download/document/linux/tbs-tuner-firmwares_v1.0.tar.bz2
    sudo tar jxvf tbs-tuner-firmwares_v1.0.tar.bz2 -C /lib/firmware/
    rm tbs-tuner-firmwares_v1.0.tar.bz2

    #git clone https://github.com/tbsdtv/media_build.git
    #git clone --depth=1 https://github.com/tbsdtv/linux_media.git -b latest ./media

    cd ~/media
    git clean -fdx
    git pull

    cd ~/media_build
    git clean -fdx
    git pull

    make dir DIR=../media
    make allyesconfig
    make -j4

    sudo make install

    sudo modprobe dvb-usb-tbs5520se


modprobe results in;

HI
You can not using this way install the drivers into a Raspberry Pi 3 system. you need using the cross-compiled. compile the drivers into the image of the Raspberry Pi 3.

Thanks
Best Regards

Hi, thanks - how do I do that? Or is a pre-built image available?

Hello,

I had the same problem.

The key point is that you should try to alter as less as possible to the (kernel) configuration! The command "make allyesconfig" is such a command that does not respect this. Even if it only rely on media sub tree, which contain dvb_usb etc.

I think (and hope :)) that I overcome this by placing a copy of kernel configuration - namely .config - from /lib/modules/$(uname -r)/build into media_build/v4l. Then I ran "make menuconfig" (which requires libncurses5-dev) and I enabled only the tbs5520se, tuner and demod drivers as modules and saving that config. After make and make install that message disappeared and the module loads without errors.
Maybe the better way would be storing the .config as .config.old to media_build/v4l as make menuconfig would yield new entries.

The problem in this case seem to be a mismatch between the module that contains rc_* functions and is provided by a default raspbian image and the media_build / linux_media module. A configuration change making the driver built-in or a module is sufficient for a mismatch.

The described approach lets you build only the drivers you need and does not require the whole kernel to be rebuild. You could also follow smile's approach. Look for building a raspberrypi kernel. There is an article with a link to a cross compiler on the raspberrypi's foundation website.


Heads up ;)

Hi lwis,

great to hear that drivers and tvheadend are working now.

Well, you already found the tbs5520se usb driver in menuconfig. This driver depends on further drivers for frontend (si2183, demod) and tuners (av201x for dvbs, si2157 for dvbc/t). You can see that in your trace (modules linked in) or by issuing lsmod. These dependent drivers are selected automatically for you, but you can disable it and select the driver manually (Multimedia Support -> Autoselect ancillary drivers (...) -> Customize TV tuners || Customise DVB Frontends).

If you encounter something like read_status failed=-11 or set_params failed=-11 in kernel log, stop tvheadend for about 10 minutes. This error is - in my opinion and up to now - tvheadend related and occurs if you enable more than one dvb sub-system (for example dvbc and dvbt) and switch between them. The 10 minutes arise from default timeout for epg grabbers in tvheadend configuration.

TBS5520SE support one mux at a time. That means you can watch or record only one channel. The exception is, that if the mux contains more than one "program" you can watch and record these simultaneously. You can find that channels by tvheadend -> configuration -> dvb inputs -> services and filter for desired mux.

Crazycat explained it in more detail in this forum or elsewhere. I cannot remember exactly where.


Cheers

Hi!
I am having exactly the same issue with tbs 5580 on ASUS tinkerboard running rockchip kernel 4.4 (armbian), but old modules removal before new ones installation does not help.

Panic follows tvheadend start - ie if I disable tvheadend service and reboot no panic. Once run tvheadend, kernel panics.

Could you please help.
Thanks in advance.

Hi,

Replying to myself:

Kernel has multimedia support built-in rather than as a separate module. Due to the changes in upstream, (some?) newly build media modules are not compatible with kernel in my case (4.4.176). Rebuld kernel with multimedia support as a module which allowed its replacement and the issue

is resolved.

Hi,
I want to use my TBS5520SE on Enigma2, but it's not supported.

Could you point me in the right direction how to setup the build environment for Vu+ Zero (MIPSEL)?

@CrazyCat or TBS Team, could you help please?

Thanks
