I have same problem with Armbian 22.02.1_Orangepi3_focal_current_5.15.25_xfce_desktop.img.

@Avtar Singh Did you find the solution? I'm in the same situation.

On power plug on, there's no problem. But after boot up and reset, sometimes error occurred in some specific sd card. Boot error message is like this. U-Boot SPL 2018.11-armbian (Feb 08 2019 - 11:33:45 +0100) DRAM: 512 MiB Trying to boot from MMC1 spl: mmc init failed with error: -110 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### It looks like same problem as this. https://github.com/RobertCNelson/armv7-multiplatform/issues/25 How can I increase mmc power up time for sd card? My environment is kernel 4.19.38 on Orange Pi Zero.

After updated Xorg package, this problem is solved.

Do you have a plan to release for Orange Pi One?

Currently, There is no mainline release for Orange Pi One. The only release of mainline is in nightly build folder and the kernel version is v4.11.8, which doesn't work SPI chipselect. On armbian latest source compiled image, v4.13.9, SPI problem is solved. Do you have any plan to release official mainline image for Orange Pi One? Thank you very much.

I got same problem. Did you find any solution?

Dev image with desktop works well with my 800x480 hdmi lcd on Orange Pi One. I just need using Chromium, so I don't want to install all the heavy desktop package. So I chose dev image without desktop option, and installed xorg and chromium-browser. But it says errors. Fatal server error: (EE) no screens found(EE) Do I have to install other things?

I'll try to build dev image with desktop at first. My LCD was hdmi 5inch 800x480. I confused the resolution. After testing, I'll share the result. Thank you very much.

At first, I used 3.x kernel with Armbian_5.30_Orangepione_Ubuntu_xenial_default_3.4.113_desktop.img. This has a problem displaying my hdmi 5inch 800x600 lcd. So I changed the kernel to 4.x with nightly build image, Armbian_5.32.170706_Orangepione_Ubuntu_xenial_dev_4.11.8.img. It displays well from u-boot. For x window, I installed Xorg and ubuntu-desktop. When I run startx, it says unable to connect to X server: Connection refused. What should I do for x window? I want to use Chromium.

I want to use 460800 baud rate on OrangePi Zero. It works 115200 baud rate. Following this, I need to change the uart clock from 24MHz to higher. https://forum.armbian.com/index.php/topic/3508-higher-uart-baud-rates-h3-nanopi-neo-air/ Is there anyone can solve this problem? I have willing to pay a fee to this. Please send me messages on facebook (ID : techcap@live.com). If I get the solution, I'll share it in this forum. Thank you very much.

I tried another. I declared new clock like below, and set serial clock to this. osc30M_clk { #clock-cells = <0x0>; compatible = "fixed-factor-clock"; clock-div = <0x8>; /* 24M/8 = 3M */ clock-mult = <0xa>; /* 3M * 10 = 30M */ clocks = <0x3>; clock-output-names = "osc30M"; linux,phandle = <0x71>; phandle = <0x71>; }; serial@01c28400 { compatible = "snps,dw-apb-uart"; reg = <0x1c28400 0x400>; interrupts = <0x0 0x1 0x4>; reg-shift = <0x2>; reg-io-width = <0x4>; clocks = <0x71>;//<0x2 0x3f>; resets = <0x2 0x32>; dmas = <0x12 0x7 0x12 0x7>; dma-names = "rx", "tx"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <0x17>; linux,phandle = <0x49>; phandle = <0x49>; }; Now the command "cat /sys/class/tty/ttyS1/uartclk" says 30MHz. But UART does not work. Could you give me any hint?

I tried to make apb2 clock to 30MHz like below. apb2_clk { compatible = "fixed-factor-clock"; #clock-cells = <0x0>; clock-div = <0x8>; clock-mult = <0xA>; clocks = <0x3>; clock-output-names = "apb2"; linux,phandle = <0x71>; phandle = <0x71>; }; But it didn't work and OPI doesn't boot.

I'm trying to use baud rate 460800bps on Orange Pi Zero. Baud rate 115200bps is working well, but above baud rate has problems, data corrupted. I found the reason that UART clock is not enough. https://forum.armbian.com/index.php?/topic/3508-higher-uart-baud-rates-h3-nanopi-neo-air/ Default uart clock is 24MHz. So I want to increase the uart clock. My OPI kernel version is v4.11.3. Current clock source seems to come from ccu. serial@01c28400 { compatible = "snps,dw-apb-uart"; reg = <0x1c28400 0x400>; interrupts = <0x0 0x1 0x4>; reg-shift = <0x2>; reg-io-width = <0x4>; clocks = <0x2 0x3f>; resets = <0x2 0x32>; dmas = <0x12 0x7 0x12 0x7>; dma-names = "rx", "tx"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = <0x17>; linux,phandle = <0x49>; phandle = <0x49>; }; On clocks, 0x2 looks like phandle. I don't know what is clock specifier 0x3f. Is it just sequence number? Now current clock source is like below. clock@01c20000 { reg = <0x1c20000 0x400>; clocks = <0x3 0x5>; clock-names = "hosc", "losc"; #clock-cells = <0x1>; #reset-cells = <0x1>; assigned-clocks = <0x2 0xd 0x2 0x65>; assigned-clock-rates = <0x23c34600 0x11e1a300>; compatible = "allwinner,sun8i-h3-ccu"; linux,phandle = <0x2>; phandle = <0x2>; }; … clocks { #address-cells = <0x1>; #size-cells = <0x1>; ranges; osc24M_clk { #clock-cells = <0x0>; compatible = "fixed-clock"; clock-frequency = <0x16e3600>; clock-output-names = "osc24M"; linux,phandle = <0x3>; phandle = <0x3>; }; osc32k_clk { #clock-cells = <0x0>; compatible = "fixed-clock"; clock-frequency = <0x8000>; clock-output-names = "osc32k"; linux,phandle = <0x5>; phandle = <0x5>; }; I think I have to declare new clock under clocks node. How can I declare apb2 or pll6 30MHz for uart? Please help me. Thank you very much.
