@Caio Lima Viana If you post pictures of the front and back of your board, someone on here may be able to identify the uart connection points

@tj13You get details by hooking up a USB uart adapter and reading the serial console output of the boot process.

unfortunately I don't have access to the serial UART of the TV box, I didn't find any pad with the tx rx labels on the PCB, I'm going to try to replace the rootfs, in the functional Armbian image, with the exception of the boot directory, then write it using multitool , I'll post here if this works. Thank you very much for the tips and quick responses

@Caio Lima Viana Yes, copying sdcard to emmc should work, there is no difference. About the reason it does not boot, if you don't get any output on the HDMI and the board does not answer on the network, serial UART is the essential tool to get some clue about. You can surely do a clean installation on eMMC with multitool, then "transplant" the whole rootfs, but if you don't know where the issue is, you may transfer the problem too and get stuck again.

I try to find where is problem with UART5 dmesg |grep serial [ 1.306076] sun50i-h616-pinctrl 300b000.pinctrl: pin-224 (5000000.serial) status -517 [ 1.306095] dw-apb-uart 5000000.serial: Error applying setting, reverse things back [ 1.306231] sun50i-h616-pinctrl 300b000.pinctrl: pin-226 (5001400.serial) status -517 [ 1.306249] dw-apb-uart 5001400.serial: Error applying setting, reverse things back [ 1.333692] 5000000.serial: ttyS0 at MMIO 0x5000000 (irq = 296, base_baud = 1500000) is a 16550A [ 1.334902] 5001400.serial: ttyS1 at MMIO 0x5001400 (irq = 297, base_baud = 1500000) is a 16550A dmesg don't show ttyS5 only ttyS0 and ttyS1 so UART5 on PIN26 header is ttyS1 not ttyS5 ?

@astrosky you'd definitely want to go with an armbian supported SBC rather than tinkering with a tvbox. Yes, tvboxes usually have one exposed UART, but it is for debug and is already in use for kernel and system logs. It can be altered to be used as a general purpose UART, but requires some effort (modify bootloader, change the kernel device tree) that IMHO it is not worth for. SBCs have their own exposed pins with two or more UARTs, SPI, I2C, I2S and GPIOs that you may easily use without having to solder and desolder things on the board. They are more suitable for serious projects.

Actually these boards have UART correct? Can the UART send communication signals? If so I'm pretty sure I can use the UART parts to create a link to Arduino and then! Have gpio ! I can't believe I didn't think of this before. But I'm certain this is feasible. Uart is a very legacy communication protocol and I'm sure it's fast enough for general purposes scripts and such! The goal is to use it like a MCU and to send commands to the Arduino with out taking up my precious USB ports!

This is so cool, I remember reading about this in the Orange Pi user manual but skipped over it because I found it annoying for some reason that I don't remember now. I set this up and man it's really convenient not to have hdmi and stuff to test linux builds and experiment with your SBC. I also found that we have to enable UART serial console in some SBCs and distros by modifying image files? Is this the case or all distros provide a way to access serial console in some way? I really like this serial console setup, thanks for that suggestion again.

Thank you for answer. I've only tested the Legacy 4.4 image briefly, and baked the latest image for rk322x. If I boot with the SD card (MULTITOOL), press the REBOOT menu, and remove the SD card, then I can boot with the latest image burned into eMMC and use all functions. I'm just curious as to why I have to go through procedures like "SD boot" and "Remove SD after REBOOT" to boot. I still don't know how to check LOG through UART.

Hello, there can be dozen of problems with those symptoms: the kernel does not boot, the image you used is bad, the board is unsupported and does not boot, HDMI does not work on your board, the eMMC is empty, etc... etc... You should try a newer image with a mainline kernel (4.4 is unsupported and unmaintained anymore) and possibly provide UART serial logs to debug the problem.

@thuvasooriya wrote rather than to use HDMI and a monitor, I used a usb-uart (usb-serial) dongle that lets me connect over the serial console with the debug pins and I'm literally able to boot up in a serial console and (even) configure networking, i.e. I didn't even need network and can change the network interface configurations. That would also be a way to troubleshoot boot up problems if there is. I used the serial debug pins/console to configure networking as more than often, the default setup of network isn't what I want, and playing with the network interfaces will lock me out of ssh. After I've network configured over usb-uart, I can then ssh remotely into the device over the network. And that if you use dynamic IP, it may help to install and use avahi-daemon and avahi-tools (i.e. multicast DNS), I installed avahi-daemon on the OPi Z3 Armbian board so that I can find it from my main linux box using avahi-browse -a , and that ssh into there could be simply ssh orangepizero3.local that's a way to practically use it headless , in fact, after I've setup things, it is now my WiFi AP on the desk.

Maybe we can bundle our effords regarding a working S805 image? I also have hundreds of new TV sticks (not boxes) with an Amlogic S805 (Meson 8B). The original Android ROM has the codename stvm8b. Currently I only have a working Android 4.2.2 image with a patched kernel for real 1080p output which can be flashed using TWRP onto the internal eMMC. I really would love to get some kind of more recent and non-Android image up and running. It's a real struggle to get any custom images as most links are dead already which makes it more complicated. Currently I have full UART access to the device and I'm able to interact with the uBoot shell. I also see the full kernel output of the working Android image and have a root shell there. But as others already pointed out kernel 3.10 is way to old to be used in production. So "porting" a more recent kernel would be great. My main goal is to get a Linux image up and running on the box which makes it still useful as device for digital signage or as a small webserver.

Among the things to try, get and set up a usb-serial (usb-uart) dongle to the debug UART pins, and you should be able to see the boot up in a serial console. The boot messages may provide a clue to what went wrong.

Hello, I'm trying to connect a serial device on my nanopi neo plus2, but the gpio uart seems to be disable, please can you help me step by step? I found some things on forums but I understand nothing .... Thank you in advance

Hi. I testing out different images for my DIY NAS project. My plan is to use the Orangepi3b board with armbian bookworm and OMV. I have built images from armbian github, (main,trunk) the edge 6.7.10 kernel is working great. But I do get some Iperf3 retries when sending from Opi3b. From Opi3b 60-70MB/s To Opi3b 110MB/s. With Orangepi own bookworm image I have 110/110 and no retries. The same with Joshua Riek's Ubuntu server image, no retries and 110/110.

The box can be toothpicked into a loader from where there are options available including ADB - which I also have no experience with. When trying to boot a generic rk3566 LE image from SD the device stays dark. Which means to me it's trying to boot. Good but not progress. I now have a UART adaptor but didnt get a word over the line yet. UART may need enabling or may be misconfigured or may not be a UART port at all. Flying blind is not great. ADB may be a more productive approach. Eyeballing the board there is a wifi 2.4/5 & BT chip (LGX9358) which had me worried cos no search engine hits but device tree says wifi_chip_type = "ap6398s" and this seems known. I tried to contact the manufacturer wrt general information and about getting maybe access to their (legacy) kernel SDK, but haven't heard back yet. Other sources suggest that this manufacturer is not interested in open source software on their products. Maybe this is true, maybe not, I'll wait, it's only been a week. There is a lot to learn and I havent spent much time on this yet, busy with other stuff.

Same issue here. Upgraded from Armbian 23.8.1 Bookworm with Linux 6.1.63-current-rockchip and now my Tinkerboard won't boot Here is the log from the upgrade process. Unfortunately, I am not home and hence cannot debug any further with an UART for the next weeks

I have same problem, when i solder usb-uart external (by ft232) i can see that my nano still working.... I try find it in armbian-config but but any sucsess....

Hi everyone, i have uptabte armbian from 23.05 to 24.1 (stable relase update) in my nano pi neo air, but arter update i cant connect to device via com port from micro usb. (no avalible devices, when i connect nanopi to my PC) How i can fix it? Armbian-config? P.S. I also soldering external usb-uart and to the nano and i see that update was sucsessful, device steel working.

Hi, I needed 921600 baud and found the same problem as you. Attached is a overlay that has worked for me for all the speeds up to 921600. Hopefully you can use this as a starting point to try higher bauds. Instructions for adding overlays are here: https://docs.armbian.com/User-Guide_Allwinner_overlays/ if you're not already aware. The problem is outlined here: https://github.com/armbian/linux/blob/sun8i/drivers/tty/serial/sunxi-uart.c#L358 - the ABP2 bus is normally 24MHz. I chose 30MHz for my case but you might have to try 54545454Hz or some of the others in that table. If you do sudo cat /sys/kernel/debug/clk/clk_summary you can see i2c and scr0(??) also share that clock - if you see any issues with those after this change it's likely the clock rate change has caused it. @MarshallMCH, @lpercifield, @Bongho Lee FYI in case any of you are still wanting this 7 years later 😆 Hope that helps, Greg uart-baud-upto-921600.dts

I tried with the last bullseyes and bookworm image, with the same result. I also tried the instructions in Armbian Documentation - Esspresso bin even if it seems obsolete by now, as it uses old uboot variable names, and contain a booiti command after sourcing the boot.scr script which itself contain the booti command; but I got the same result, even if the inird addr was distinct. Please what is wrong, and what I'm missing in this uboot environment.

Now it is systemd https://opensource.com/article/20/5/systemd-startup#targets https://www.cyberciti.biz/faq/switch-boot-target-to-text-gui-in-systemd-linux/ There may be some features if you review the user guide https://docs.armbian.com/User-Guide_Getting-Started/ and maybe check in the tutorials forum section https://forum.armbian.com/forum/40-reviews-tutorials-hardware-hacks/ but that for anything more complicated, what I did instead is to get a usb-uart dongle connect to the 3 pins for 'debug' console, check the documentation for Orange Pi Zero 3 from the vendor. Then that you can literally boot up in a console / terminal app, login on the console / terminal app etc even for the first time. For now I keep the steps as a set of manual command line commands I run, including changing the passwords etc. And basically 'copy and paste' the commands say from a pre maintained file with the steps and commands. edit: I think for that matter, it is quite possible to *script* that say using python https://pyserial.readthedocs.io/en/latest/ and have the 'auto setup and config' all done over serial usb-uart over that debug port. and for those who are 'ancient' enough, there is tcl/tk https://www.tcl.tk/ and expect https://wiki.tcl-lang.org/page/Expect https://wiki.tcl-lang.org/page/BOOK+Exploring+Expect https://gist.github.com/fstab/6d39fae3a436d9bd6cecb1d9fde9a667 ---- I think it is possible to directly customize the image though. That would take mounting the image as a loop device in Linux (prefably make a copy of it). And perhaps for the config files (e.g. in /etc) on your running SD card, copy them out and replace the same in the image.

Uart port works fine in the latest image `Armbian_community_24.5.0-trunk.93_Orangepi3b_jammy_legacy_5.10.160_gnome_desktop.img.xz`
