teacup

Could you please explain? I have used meson-g12b-gtking-pro.dtb built within v20200821 sources available on github, the dev/mainline kernel branch (5.9.0-rc3 kernel version) and it seems to work fine now even with 20200904 release with my GT-KingPro (kernel 5.8.5). Do you mean there is some major issue due to which GT-KingPro cannot be supported? Like something with gpu acceleration for example? I am particularly interested into running tvheadend with Hauppauge WinTV-dualHD tuner - managed to build tvheadend 4.2 and could get it running with the tuner streaming 9 dvb channels to PC. The great thing with 5.8.5 kernel is that the WinTV-dualHD tuner works nice in usb3 ports of GT-KingPro. That is not the case with amlogic 4.9 kernel unfortunately, where I get em28xx 1-1.1:1.0: writing to i2c device at 0xc8 failed (error=-5) errors when using usb3 ports. With amlogic 4.9 kernel the tuner works only in usb2otg port of GT-KingPro. Strange thing is that with 5.8.5 kernel the tuner does not work in usb2otg port, getting the same i2c errors as present with 4.9 and usb3 port. I wonder about that opposite behaviour of usb ports in amlogic 4.9 vs mainline kernels and if it could be fixed that it would work with both type of usb ports in either of the kernels.

Hi @balbes150, just booted the 20200902 version of Armbian_20.09_Arm-64_focal_current_5.8.5_desktop.img on my GT-King Pro tvbox, using meson-g12b-gtking-pro.dtb from armbian build done from v20200821 commit. It works nice (as far as a quick boot test), including playback of the test video from desktop. Thank you. The only hiccup encountered was unexpected shrink of mmcblk1p2 by about 150MB on the first boot making the next boot not working. Probably could have been caused by that I had not used the full image but rather copied only the content from the two partitions to my sd card already partitioned for other uses, adjusting 'root' partition label in extlinux.conf. Fixed it by resize of the mmcblk1p2 to the full size which I had before the trial, luckily not loosing data that I had there (besides the armbian rootfs) before the test. Could you please include meson-g12b-gtking-pro.dtb in your builds? Could you please push your changes corresponding to v20200902 to the github? Thanks a lot.
