  1. Hi, what kernel did you use? Can you upload your dts to pastebin?

    Calibrating battery gauge on A33 tablet

    You have to update the devicetree blob or fex file with the new capacity and internal resistance of your new battery, then reset the AXP to restart the self-learning process. It will take a couple of cycles for the gauge to become correct again. http://linux-sunxi.org/Fex_Guide#pmu_configuration The two most important ones are pmu_battery_rdc: battery internal resistance in mΩ pmu_battery_cap: battery capacity in mAh There might be other ones you might want to tweak, but you have to keep in mind the overall power budget of the device and the charger/power adapter. Also don't burn down your house :)

    Questions on Ayufan's Rock64 Images.

    What Igor said :-), you can also use an overlay to enable it at run-time. Ayufan just added a script to toggle existing nodes without creating an overlay for each. https://github.com/ayufan-rock64/linux-build/blob/master/package/root/usr/local/sbin/enable_dtoverlay The eth1 interface was disabled by default since it creates issues when there is no magjack mounted on the Rock64 for it, e.g. when you don't have the top-board with the audio DAC, this is also the usual Linux convention for boards with headers.

    Rockchip RK3399

    Radek, I would try and build normal mainline Linux for your board, upstream u-boot/atf/linux are pretty advanced by now...

    If a kernel compiles, will it work?

    You have to be aware that the 4.4.x kernel series is the BSP kernel maintained by Rockchip (mostly based on Linaro LTS releases), which is different from mainline Linux with regards to drivers and other patches. RK's upstream for BSP Linux is here: https://github.com/rockchip-linux And you get all the info from: http://opensource.rock-chips.com/wiki_Main_Page Mainline Linux is developed by the community, but RK supports it too with patches: https://patchwork.kernel.org/project/linux-rockchip/list/ You have to decide what kernel you want to run on your board, BSP is generally a bit more complete, for example it has VPU drivers, see status matrix here: http://opensource.rock-chips.com/wiki_Status_Matrix So you can't just patch your 4.4.x codebase up to current mainline, you have to work from the upstream repository...

    Custom H3 board Kernel Issue

    Do you have the fex files (if BSP Linux/Android )for the custom board or the devicetree (if mainline Linux) file? You can extract the devicetree blob from your custom board's Linux image and use that maybe, what kernel is running on the custom board?

    Custom H3 board Kernel Issue

    The first thing to do is to compare the schematic of your board to the schematic of whatever board you take as a reference for the image and find out all the differences, then take that board's devicetree file for u-boot and for Linux and update it with all the differences. Most of the time it's power related things that are controlled in a different way and what GPIOs are used for various controls, different pin mux settings for busses that have multiple pinouts etc...
  8. Those are not really video drivers, it's more or less just the glue layer between Cedarx (AW's proprietary video libraries) and the kernel drivers for Android BSP (Linux 3.10.x).... so it's more or less just a reference to look up some things that are not in the documentation (which might be released soon...)
  9. Leapo has started porting RPi.GPIO to Rock64 as R64.GPIO, you can find her work in progress at https://github.com/Leapo/Rock64-R64.GPIO Original thread with instructions/updates is here: https://forum.pine64.org/showthread.php?tid=5902 She also made a more simple tool to work with GPIO: https://github.com/Leapo/Rock64-BashGPIO

    using ov5640 with sopine/pine64so baseboard

    There are only contacts on one side of the FFC, so if you plugged them in the wrong way, should still be fine since it's isolated? Did you check if the BPi camera has the same pinout as the Pine64 camera module?

    Librecomputer Renegade RK3328

    Does anyone know where the sources for the image come from?

    Want Some Information????

    I have three of the V3s based LicheePi Zero's and they work ok, V3s mainline u-boot and 4.16.x Linux work out of the box... you can still buy those at the taobao shop page Zepan set up...
  14. Can you post a boot log with earlyprintk enabled? There are about 7 seconds missing from it....

    Orange Pi One Plus

    I tried to build that u-boot 2014 release from the BSP too... after fixing the error in the Makefile like you mentioned, I also got stuck on the u-boot build unless I use the specific linaro toolchain contained within that BSP drop, but the scripts are totally broken because they split up the BSP into several repos...
