DVB support for R2

sunarowicz · October 20, 2017, 9:45pm

My intention is to have DVB support available in R2 in order to use it as Tvheadend server with USB DVB stick. Currently I run the latest available Ubuntu Mate image 2017-09-04-ubuntu-16.04-mate-desktop-bpi-r2-sd-emmc-v1.2.0.img on my R2. So started to build DVB modules provided by linuxtv.org but I ended very soon with the following error:

File not found: /lib/modules/4.4.70-BPI-R2-Kernel/build/.config

The /lib/modules/4.4.70-BPI-R2-Kernel/build is symlinked to a nonexisting /work/BPI-R2-bsp/linux-mt. I installed linux-headers-generic and kernel-source from default repositories but it didn’t helped because it installed these for kernel 4.4.0-97.

Could you please anybody give me an advise how to get the right 4.4.70-BPI-R2-Kernel source and headers into my R2?

Thank you in advance.

Thank you Frank. Ok, I cloned kernel source, changed symlinks to point from /lib/modules/4.4.70-BPI-R2-Kernel/build and source to linux-mt directory in cloned kernel source. But the problem remains because the requested .config file is missing in this directory. Do not know how to get it so I just tried to create it as a symlink to Kconfig file in the same directory. And started again building the DVB support. Now it complains as follows:

Preparing to compile for kernel version 4.4.70
You appear to have loadable modules turned off in your kernel.  You can
not compile the v4l-dvb drivers, as modules, and use them with a kernel
that has modules disabled.

If you want to compile these drivers into your kernel, you should
use 'make kernel-links' to link the source for these drivers into
your kernel tree.  Then configure and compile the kernel.

Are loadable modules really turned off in kernel? Or is this just result of my mistake when I made .config the same as Kconfig? So how to turn loadable modules on or better how to get (make) the right .config in kernel sources? I’m sorry for my stupid questions, but I do not have experience with kernel bulding and the things around…

frank-w · October 21, 2017, 12:23pm

.config and Kconfig are 2 different files. Kconfig defines entries for menuconfig and .config is configuration of kernel. You can create .config by importing the defconfig using “make mt7623n_evb_bpi_defconfig” in folder linux-mt (the folder where are kernel-sources). The defconfig itself lies in arch/arm/configs

unless your DVB hardware handles its own scaling (probably not) then the framerate will be terrible - there’s no hardware scaling in X11 atm

sunarowicz · October 22, 2017, 6:06pm

Not a problem. I don’t want to play DVB streams on R2. Just to make it a Tvheadend server for streaming to another clients on LAN. So only SATA and GLAN performance is of my concern. Right after making my USB DVB stick working well with R2, of course…

Please clone the code to a host , and run ./build with option 1 to build entire BSP.

And then build DVB driver on the host,(cross compiling).

sunarowicz · October 23, 2017, 10:51am

Thank you gary, I will try that.

BTW: I believe I’m already not far from having DVB support successfully built on R2. Thanks to @frank-w help I proceeded to the point where most of the DVB divers are built but it failed on building the others. I already thought of cross compiling on host (building on R2 is too slow) but didn’t know how to do…

sunarowicz · October 23, 2017, 9:24pm

Unfortunately I’m not able to build BSD. I do it in a virtual machine with Ubuntu Mate 16.04.03 32 bit. Both gcc-arm-linux-gnueabihf and u-boot-tools are installed. There are many warnings in the build output and finally it ends with syntax error I really don’t uderstand.

Any idea what is wrong?

can you please confirm if the tool mkimage is installed? If not, please install it by re-installing u-boot-tools.

Yes, it is installed.

I finally succeeded in building the BSP. Believe me or not the success trigger was to built it on x86_64 Ubuntu Mate 16.04 instead of the i686 architecture of the same system! I have two freshly installed VMs one with i686 and the other with x86_64 version of Ubuntu Mate 16.04. While BSP building fails in the first one, it finishes well in the second. No idea why at all…

But now I ran in another problem when proceeded to building the V4L. When I have forgotten to set cross compiling it compiled against the 4.10.0-37-generic system’s kernel well. But when I corrected my mistake and set cross compiling against the just built BSP tree, it failed, see below.

Couldn’t it be missing the /lib/modules/4.4.70 for example? I’m afraid that despite cross compiling being set by make -j5 release DIR=/home/jirka/BPI-R2/BPI-R2-bsp/linux-mt/ it still uses the system /lib/modules/4.10.0-37-generic.

I appreciate any idea on what could be wrong.

I’m definitely out of any idea how to cross compile the DVB driver on my PC. Compiled BSP is my only progress in last days. Compiling DVB drivers directly on BPI-R2 against compiled BSP fails. And I do not know how to cross compile it on PC. LinuxTV provides no info on that here: https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

I found some hints in some forums I tried but no success. I’m not experienced in compiling and I didn’t found any guidance I could follow. Really do not know how to proceed any further:-(

I would be glad for any help.

To support DVB, looks like some patches of linux kernel should be applied, right? If yes, this will be a huge task.

make -C …/linux apply_patches make[2]: Entering directory ‘/work/media_build/linux’ Patches for 4.10.0-37-generic already applied.

sunarowicz · October 26, 2017, 9:14pm

To be honest I do not know if any kernel patches should be applied. But I have read through several forums on similar topic and did not notice any need for patching the kernel. Unfortunately all the information was several years old, I did not find any up to date. Maybe the most useful list of steps to be done I found is here: http://forum.lemaker.org/forum.php?mod=viewthread&tid=2172&extra=&page=6. But marked as not working though.

BTW when you have a look at my DVB build output in my post above DVB support for R2, you can find there also:

make -C ../linux apply_patches
make[2]: Entering directory '/home/jirka/BPI-R2/media_build/linux'
Patches for 4.4.70 already applied.

Above information is from your log, looks like the kernel 4.4.x is not supported.

sunarowicz · October 27, 2017, 6:58am

I don’t think so, Gary. I know this part of the log. I’m sure this means that only these few drivers are not supported but the others (there are hundreds of them) are supported. The LinuxTV V4L-DVB drivers will work only in conjunction with relatively modern 2.6 kernels; specifically 2.6.31 and up., see: https://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

Kernel version is definitely not the problem.

The problem is that I do not know how to set and do cross compiling of the drivers. I never did it before. Linuxtv does not provide any information on that. And any piece of information on similar topic I find on Internet is a bit different of the others. So I’m lost on how to proceed in order to cross compile it in fact. I believe it has to work when done in the right way.

DVB on R2 already works to me. As usually the problem was in between the keyboard and chair. I went to totally wrong direction earlier. There is no need to get the DVB drivers from LinuxTV website and compile them. DVB support is already in kernel for years.

So to enable DVB support on R2 this has to be done:

Get R2 source code from https://github.com/BPI-SINOVOIP/BPI-R2-bsp and follow all the steps in order to be ready for building it.
Configure kernel, ie. run ./build.sh and select option nr. 4.
Enable DVB in Device Drivers/Multimedia support/Digital TV support and select appropriate device drivers you need in Media USB Adapters there.
Save the kernel configuration to .config.
Build all the stuff, ie. run ./build.sh and select option nr. 1.
Update both u-boot and Linux kernel according to instructions on the same webpage. One note here. If you run bpi-update on the host PC not on R2, you has to use the command as follows: bpi-update -d /dev/sdb -c bpi-r2.conf, where /dev/sdb is your SD card with burned R2 Ubuntu image.

And that’s it! After booting R2 from this SD card with DVB USB stick inserted DVB should work. I’m running Tvheadend on R2 already for several weeks. It works as it should. No problems so far.
