| configuring Euler Bus pin generate interrupt |

Hi, I am looking for help to configure Euler Bus pin in Pine A64+ to generate kernel interrupt. For example. Pin no. 27(PB2) in Euler Bus, have multiplexing function of PB_EINT2.
I would like to register interrupt handler for this pin in the kernel with a help of a simple kernel module. Need help on how to define this pin characteristic in device tree file so that it can be configured to receive external interrupt. Any help will be highly apricated.
Regards
RANJIT

| boot loop with lcd plugged in |

I am running Ayufan's linux bionic build. I started with bionic-minimal-pine64-bspkernel-0.7.29-138 (there was no bionic minimal for 7.30)
After fiddling with netplan (it didn't create a config file by default), manually setting DNS (was not working via DHCP), installing mate, and doing a bunch of updates I am now stuck with failing to get it running off the LCD. I edited the uEnv.txt under boot and added:
disp_screen0=lcd
but on boot it power cycles after trying to initialize the screen.
I have tried multiple 2.1a power adapters and cables but no go. What is odd is I had the LCD working with an older image a while back with one of the same adapters and cables. Any advice?
thanks

| Question about gstreamer-rockchip and mpp |

Hellow everyon
ROCKPro64 board hardware encoding related questions.
I have built and installed gstreamer 1.15.0 version, gsteamer-rockchip, and mpp on the ROCKPro64 board.
For video and audio input of gstreamer, magewell's Pro HDMI capture card is installed in PCI slot.
I also built and installed gst-plugins-base, gst-plugins-good, gst-plugins-bad, gst-plugins-uqly, gst-libav, gst-omx, gst-python and gstreamer-vaapi.
gst-launch-1.0 v4l2src device = / dev / video0! video / x-raw, format = NV12, width = 640, height = 480, framerate = 30/1! queue! x264enc! queue! h264parse! mpegtsmux! filesink location = 2k.ts
With the above command, the video input is normally encoded and saved as a 2k.ts file.
However, if you enter mpph264enc as below, an error occurs.
gst-launch-1.0 v4l2src device = / dev / video0! video / x-raw, format = NV12, width = 640, height = 480, framerate = 30/1! queue! mpph264enc! queue! h264parse! mpegtsmux! filesink location = 2k.ts
Setting pipeline to PAUSED ...

mpp_hal: mpp_hal_init could not found coding type 7
mpp_enc: mpp_enc_init could not init hal

If you know the cause or solution to the above problem, please help me.
Thank you~

| USB 3 type-C port Thunderbolt compatible? |

I have a project I'm working on that will be using a portable Thunderbolt 3 USB type-C display (hooray for only one cable!) and was looking for an SBC that would be able to drive it. I saw that the ROCKPRO64 has a USB type-C with DisplayPort 1.2, but I wasn't sure if that means it actually supports Thunderbolt 3 or not.

| DietPi not booting |

I saw that DietPi was highly recommended and had a Pinebook version. I created a SD card with Etcher and the Pine64 Installer but neither will boot properly on my Pinebook 14 with the original 1366x768 display and the 64GB eMMC upgrade.
I see the same problem with the Dev Armbian using Kernel 4.19, so far other than the stock OS I have only been able to get Armbian Stable Kernel 3.10 to boot from SD and later install to the eMMC (had to format ext2 for it to work).
Any ideas? I have the serial adapter on order to see if I can catch any messages on the serial console.

Is it possible to install Linux to pinebook to LUKS-encrypted partition? Is there any generic instruction (that is suitable for all or most distros)?

I have the rock64 4gb board with bionic-lxde-rock64-0.7.8-1061-arm64.img installed. Did apt-get update and upgrade, Trying to install gr-hpsdr with the error as follows :
