hello @dellfer, there's something wrong with pmic from the log, usually the boot process will set parameters for: vdd_center 900000 uV vdd_cpu_l 900000 uV vdd_log 1100000 uV it might be caused by the uboot defconfig & kernel dts changes. have these been modified? if so, what are the modifications?

hello @robotmyst, which image are you using? may i know the version please

hello @robotmyst, may i have the complete dmesg log please?

hello @robotmyst, try use tinker config to enable the camera module ov5647 sudo tinker-config

hello @Krz62c, are you using v.3.0.20 Tinker Board 2 /2S Debian 11 (kernel 5.10) v.3.0.20 as os image?

hello @stefanTimm, it's a framework defect and cannot be fixed without compiling a new .img.

hello @Krz62c, what's the source of this file? where did it come from?

hello @stefanTimm, we're aiming to have this issue resolved in the next release in april

hello @stefanTimm, are you using the os from the official tinker board site? or did you compile the android image yourself?

hello @normally96, absolutely. please download and install the platform tools from https://developer.android.com/tools/releases/platform-tools the process is similar to tinker edge r:

hello @normally96, we don't have built in linux terminal in the android os for tinker board, perhaps you can try 3rd party apps such as termux https://termux.dev/en/ and see if it fits your needs

hello @normally96, not sure if i quite catch it, but i assume that you're trying to use linux instead of android? the easiest way is to download the debian os from the official website, use the balena etcher to flash the image to a sd card, and use the sd card to boot the board reference: Tinker Board 2 & 2S · TinkerBoard/TinkerBoard Wiki

hello @ErrorFinder, the boot order is sd card > emmc by default so technically if a sd card with img is loaded, you don't have to do anything and the board will boot from sd

hello @Jovan, 1. do you have idea which stage it boots to on tinker board r1.03? (u-boot, system ... etc) 2. is it possible to collect the uart logs for us to investigate? (please see the post embedded for the how-to on using serial dongle) 3. have you tried using the os from the official website and if so does the same issue happen? (it's worth noting that there's a cap on the board that keeps the board in maskrom mode if not removed)

hello @Fantasy, you can download the boot.img of android v.3.0.2 here: https://www.asuswebstorage.com/navigate/a/#/s/C2F055F2E3A64D46BA7C63A4BF9F6D864

hello @Jovan, what have you added in your master image? is there anything related to /proc/boardinfo ?

hello @Jovan, if you click the plus + symbol next to download button on Tinker Board you can see the release notes for each version

hello @nikolic730, reasons can vary, you might want to check if it works with another cable, or the other setting that i listed in another post

hello @ryo, we've tested your sample code and cannot reproduce the issue. 1. please ensure the multi-function is switched to uart0 (pwm0, pwm1, pwm2, pwm5 are all disabled, otherwise it'll be conficted with uart0, this can be checked in /boot/config.txt ) 2. does ttys0 exist under /dev/ ? ls /dev/ if the answers above are yes, what does the error look like?

heloo @Fu-., looks they're in spi mode. to further investigate the issue: 1. which version of the os are you using? 2. is tinker board 2s connected to other peripherals/ components?

hello @FlostonParadise, you can check the drawings for reference: Tinker Board there are also aluminium cases avaiable in the market

hello @Fu-., from what you decribed it's possible that it might be a hardware issue, but i'm not 100% sure. have you also modified the settings of /boot/config.txt ?

hello @Fu-., have you tried using sysfs instead?

hello @Fu-., setting spi is not supported in wiringpi what are you setting for gpio2c6 and gpio2c7 and what's your configuration?

hello @Augusto Hertz, the android releases can be found on the official website: Tinker Board the latest version is: Tinker Board 3 Android 14 (kernel 6.1) V.1.0.9
