    Why people every time think on worst possible option? It is more likely that they just forget to disable some clocks for some HW units which still run and eat power.

    @zador,
    maybe a multimedia subsection should be made with a big red warning saying "GPU doesn't decode video" with the link to http://www.cnx-software.com/2013/12/10/most-embedded-gpus-do-not-support-hardware-video-decoding-acceleration-the-vpu-does/
     
    This is most detailed description I could find in datasheet:
     
     
    Obviously, 10 bit HEVC is not mentioned anywhere. Of course they might just forget to state it, but until I see working 10 bit decoding, I will claim that HW acceleration of 10 bit HEVC is not possible. I'm not sure if CPU is fast enough to do it in SW.
     
    @hojnikb,
    maybe because they wanted to join 64 bit ARM hype? Easy, take H3 and change 32 bit core with 64 bit, update Mali cores and you are done. As you may noticed, sales are fuelled with marketing bullshit instead of common sense.

    Be aware that GPIO pin is capable sourcing only about 20 mA of current which is waaaaay too low for running any kind of motor. You need to put some kind of transistor in betweeen, like MOSFET. You have plenty tutorials on the net.

    I will update audio drivers from tinaos, which improves I2S (reported in another thread). Based on the fact that HDMI also uses I2S internally, I hope this will improve situation. From what I know, tinaos and H5 BSP codebases are not very far apart.

    Yes, there are at least two - No HDMI documentation and no or GPL incompatible license for HDMI code in BSP kernel.

    Little bug here. You rounded to commonly used 148.5 MHz, which also might be fine, however, in this case you have to change pll_video to 297 (148.5 * 2 = 297). Another, originally recommended, option would be to use 147000000 Hz (lesser error) and pll_video set to 294 (as it is now).

    No, 297 is default value and the only correct one for 1080p

    yes, it has same or better functionality and it must be present anyway (pinctrl) if you want to have useful kernel.

    GPIO sysfs interface should be the same on both, mainline and BSP, kernels. I checked that a month or so back. I think the only work which needs to be done here is identifying differences between the boards and implement this in a sane way.

    serial console, ssh, wherever you have access to the console... You can also add command to load it at boot, but for that you still have to have access to some kind of console.
     
    @igor,
    maybe you can make tv driver built-in? Seems that this is common issue and mostly chicken - egg problem if user has fresh image without access to the serial console and hdmi monitor.

    jernej got a reaction from tkaiser in More proper testing - better Armbian experience   
    I just learned on U-Boot HDMI driver example that kernel implementation is not complete. Most importantly, it is missing code for changing PLL_VIDEO clock, which is important code for supporting otherwise non suported resolutions.

    Well, it could be that the issue is the same. I fixed my U-Boot driver. It seems that we shouldn't adjust addresses at all. Hm... I should test that also with One or Lite, but currently I don't have such board at hand. Do you?

    I managed to write H3 HDMI driver for mainline U-Boot. Source can be found here:
    https://github.com/jernejsk/u-boot
     
    You should also add CONFIG_VIDEO=y to defconfig for your board.
     
    It should work nicely for standard resolutions (720p, 1080p). Other resolutions might work, but some additional work needs to be done. Currently, this can be used for working with U-Boot (instead of serial console) or splash screen.
