[LINUX] Use PX-S1UD / PX-Q1UD with Jetson nano


Since there were many articles on building a recording server on Raspberry Pi, I thought that Jetson could also build it, and it is a summary of various stumbling blocks. The reason I decided to build with Jetson nano was that when I looked at the specifications, the encoding performance was4K @ 30 | 4x 1080p @ 30 | 9x 720p @ 30 (H.264/H.265) Since it is said that 4ch real-time encoding can be done aside from the necessity. ?? ?? I started building it. The focus is on getting the tuner ready for Jetson, so please refer to other articles for recording setup and more.

What you need

Prerequisite environment

OS installation on Jetson nano and terminal operation with SSH etc.

OS environment

Jetson Nano Developer Kit SD Card Image JP 4.4 Kernel 4.9.140



In the above environment, if you stab the PX-Q1UD,


$ dmesg
[ 1942.289567] usb 1-2.1.1: new high-speed USB device number 11 using tegra-xusb
[ 1942.310251] usb 1-2.1.1: New USB device found, idVendor=3275, idProduct=0080
[ 1942.310257] usb 1-2.1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1942.310261] usb 1-2.1.1: Product: PX-S1UD Digital TV Tuner
[ 1942.310265] usb 1-2.1.1: Manufacturer: PLEX Digital TV Tuner

You will only see a kernel message like this and the DVB driver will not be applied. This is because the DVB driver is omitted in the Jetson standard kernel. ** First stumbling block: sob: **

Kernel build

There is a very easy-to-understand reference article. Please refer to here for the meaning of the command. https://qiita.com/yamamo-to/items/6fc622df7b5cce3eccfb

Kernel config

Commands from kernel download to displaying the Config setting screen


$ sudo jetson_clocks
$ sudo apt install -y libncurses5-dev
$ cd && mkdir kernel && cd kernel
$ wget https://developer.nvidia.com/embedded/L4T/r32_Release_v4.2/Sources/T210/public_sources.tbz2
$ tar xvf public_sources.tbz
$ cd Linux-for-Tegra/source/public
$ tar xvf kernel_src.tbz2
$ cd kernel/kernel-4.9
$ zcat /proc/config.gz  > .config
$ make menuconfig

Download destination of latest source L4T Driver Package (BSP) Sources is the URL

If you go to this screen, after some time,

スクリーンショット 2020-05-11 19.02.08.png Since the menuconfig screen is displayed, Go to Device Drivers-> Multimedia support. スクリーンショット 2020-05-11 19.02.17.png スクリーンショット 2020-05-11 19.02.35.png

Within Multimedia support

I will change the area. (There may be unnecessary things)

After changing it, save it with Save and hit Esc repeatedly to exit.

Kernel patch

It would be nice if I could build and use it with this, but it seems that there is a bug in the Siano driver when using it with arm64, and when I insert the tuner, it hangs after a certain period of time. ** Second stumbling block: sob: **

If you check dmesg smsusb:smsusb_onresponse: error, urb status -71, 0 bytes smmu_dump_pagetable What's mc-err What's wrong I get an error like this.

A patch to solve the problem has been released, so I will apply it.

Very grateful reference article https://blog.ayushio.com/2018/12/27/rock64-record/


$ cd ~/kernel/Linux_for_Tegra/source/public/kernel
$ wget -O siano.patch https://patchwork.kernel.org/patch/10256121/raw/
$ cd kernel-4.9
$ patch -p1 < ../siano.patch



$ make oldconfig
$ make prepare
$ make modules_prepare
$ make -j4 Image && make -j4 modules

It takes about an hour. Let's cool it down.



$ sudo make modules_install
$ sudo cp -p /boot/Image /boot/Image.org
$ sudo cp arch/arm64/boot/Image /boot/Image

Reboot when finished so far (it will take some time)


After inserting the PX-Q1UD / PX-S1UD into the USB port, When I run dmesg,


[ 2402.115532] usb 1-2.1.1: new high-speed USB device number 10 using tegra-xusb
[ 2402.136510] usb 1-2.1.1: New USB device found, idVendor=3275, idProduct=0080

[ 2402.189721] smsmdtv:smscore_init_ir: IR port has not been detected
[ 2402.189724] smsusb:smsusb_probe: Device initialized with return code 0

If such a log flows and the device exists under / dev / dvb /, it is successful.


I was surprised that there were many articles in Japanese. It absorbs faster than English, so it's very helpful. Thanks to those who shared it as an article.
