I switched to 4.20. I tried many different options with no luck. I also prepared new .bin file -> following /documentation/EDID with no luck. I just can't believe that it is so hard to change that pixelclock from 27000 to 32100 (screen is 800x480 and it works with 66Hz). It is just one number that worked good using fex files... I'm completly disappointed

Also I can not see any output information considering HDMI via UART during boot. It seems to me that the code of sunxi_display.c (/divers/video/sunxi of u-boot) is not enabled and I do not know how to fix it.

The mass of codes kills me... Appreciate any help ... Thanks Jarek

Yes I found EDID data are corrupted. I tried to get proper EDID by your customized u-boot: https://github.com/jernejsk/u-boot Using uart debug I got: HDMI connected: EDID block 0: checksum error, retrying EDID block 0: checksum error, retrying EDID block 0: checksum error But I found a solution and will try to preapre patch. I am completly new to such thinkgs so it will take some time. Also my C++ is kind of basic-moderate... I also noticed that u-boot is switching to 1024x768 in sunxi_display.c: video_get_ctfb_res_modes(RES_MODE_1024x768, 24, &mode, &sunxi_display.depth, &options); so I changed 1024x768 to 800x600 - this resolution I used as guided here: https://www.instructables.com/id/Orange-PI-HowTo-Set-It-Up-to-Use-With-a-5-HDMI-TFT/ and corrected in videomodes.c : #ifndef CONFIG_VIDEO_STD_TIMINGS { 640, 480, 60, 39721, 25180, 40, 24, 32, 11, 96, 2, 0, FB_VMODE_NONINTERLACED}, { 800, 600, 60, 27778, 36000, 64, 24, 22, 1, 72, 2, 0, FB_VMODE_NONINTERLACED}, {1024, 768, 60, 15384, 65000, 168, 8, 29, 3, 144, 4, 0, FB_VMODE_NONINTERLACED}, { 960, 720, 80, 13100, 76335, 160, 40, 32, 8, 80, 4, 0, FB_VMODE_NONINTERLACED}, {1152, 864, 60, 12004, 83300, 200, 64, 32, 16, 80, 4, 0, FB_VMODE_NONINTERLACED}, {1280, 1024, 60, 9090, 110000, 200, 48, 26, 1, 184, 3, 0, FB_VMODE_NONINTERLACED}, line: { 800, 600, 60, 27778, 36000, 64, 24, 22, 1, 72, 2, 0, FB_VMODE_NONINTERLACED}, to { 800, 600, 60, 32100, 36000, 64, 24, 22, 1, 72, 2, 0, FB_VMODE_NONINTERLACED}, 27778 I figured out from the rest of u-boot code is my PLL so I changed to 32100 (321 is PLL from fex file) LCD started to work. I assume that good way is to prepare patch and recompile all and than install by dpkg. So if someone wants to patch just do or not. Let me know if this is good way. Thanks Jarek

Hello, I am new to Orange PI and Armbian. I try to configure orange pi to run chineese LCD 5 inch screen via HDMI. I managed to do that using lubuntu downloaded from orangepi server. I changed fex file to what I found on the internet: [clock] pll_video = 321 [disp_init] disp_init_enable = 1 disp_mode = 0 screen0_output_type = 3 screen0_output_mode = 2 screen1_output_type = 3 screen1_output_mode = 2 fb0_width = 720 fb0_height = 480 fb0_scaler_mode_enable = 1 fb0_pixel_sequence = 2 fb0_format = 4 fb0_framebuffer_num = 2 fb1_width = 720 fb1_height = 480 fb1_scaler_mode_enable = 1 fb1_pixel_sequence = 2 fb1_format = 4 fb1_framebuffer_num = 2 [hdmi_para] hdmi_used = 1 hdmi_x = 720 hdmi_y = 480 hdmi_power = "vcc-hdmi-18" hdmi_cts_compatibility = 1 After positve tests I wstiched to Armbian 5.72 kernel 4.18.17-sunxi. Generaly I could not find on the inter / googled/ searched thru armbian formu waht should I do to recofigure sam as in fex files. What I understad new kernels does not support fex files any more. Is there any way to change HDMI cofig simillar way as in fex files? Currently I try to recompile kernel (never did that before) I also changed orangepipcplus.fex file which i found in armbian git repository. I would appreciate any help or links. Thanks!
