  1. Hello Igor, thank you for your fast reply. I already tried the suggestions... but did not succeed. As interim solution I will use the working Raspberry Pi. When I have learned more about armbian kernel hacking I will come back with a specific question. Thank you and best regards, Richards
  2. Hello, I want to use Armbian on a Cubietruck with an Onyx Boox Max 2 ebook reader (HDMI port) as display. I tested Armbian Stretch mainline kernel 4.14.y and Armbian Xenial desktop legacy kernel 3.4.y. But with both systems I get a black screen. I use the serial console to access the cubietruck. When I plug in the HDMI cable I get following info on Armbian Xenial desktop legacy kernel 3.4.y: <6>EDID version: 1.3 <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP <6>Using above mode as preferred EDID mode <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP <4>Unimplemented SVD code 50 <4>Unimplemented SVD code 50 <4>Unimplemented SVD code 50 <4>Unimplemented SVD code 50 <4>disp_clk: Could not find a matching pll-freq for 53900000 pclk <4>disp_clk: Could not find a matching pll-freq for 53900000 pclk <4>disp_clk: Could not find a matching pll-freq for 108100000 pclk <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_VideoData_Block: VIC 50 support <6>Parse_AudioData_Block: max channel=2 <6>Parse_AudioData_Block: SampleRate code=7 <6>Parse_AudioData_Block: WordLen code=1 <6>Find HDMI Vendor Specific DataBlock <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP <6>PCLK=125000000 X 2104 2244 2284 2384 Y 1560 1565 1570 1590 fr 32 NP I get the message directly on the serial console. I also own a Raspberry Pi 3 and tested Raspbian Stretch with Desktop (updated 2018-11-13 version). In the beginning I also got a blank screen. But I found some very good info on the internet (especially https://www.mobileread.com/forums/showthread.php?t=295328 ), so I got it to work. On my Raspberry Pi 3 I use the following in /boot/config.txt : hdmi_force_hotplug=1 hdmi_cvt=2200 1650 33 0 hdmi_group=2 hdmi_mode=87 max_framebuffer_width=2200 max_framebuffer_height=1650 I tried to set the corresponding information in Armbian on cubietruck. But I did not find the correct config files. Perhaps it is possible to use the EDID... info above to create a configuration? I would prefer Armbian Stretch mainline kernel 4.14.y, but a configuration for Armbian Xenial desktop legacy kernel 3.4.y is also very welcome. Any help welcome! Link to armbianmonitor log (HDMI cable was plugged in while booting): http://ix.io/1vpt For the log I booted a fresh image, so no updates. But no change with updated and beta system. Please tell me, if you need more information. Thanks in advance, best regards, Richards
