hello @Ethan_Lin, 1. from what you've described i'd suggest to check the devices (the dac, adc) 2. please collect the logs when the issue occurs, you can use adb with the command: adb shell su -c dmesg > dmesg.log

hello @Ethan_Lin, what's the os/ version and i2c bus you're using? did you connect it to other peripherals?

hello @sinoj, you will still have to build from sources uploaded by asus: Android for ASUS Tinker Board Series · GitHub but the tinker os (android) is integrated from aosp and you can change the configurations if you need

hello @gavin67890, for csi cameras, the coral camera is the only camera module supported on tinker edge t thus far: https://tinker-board.asus.com/download/Tinker_Edge_T_Device_QVL.pdf though there's no qvl for the uvc cameras, we use logictec c930e for testing

hello @wahaha, sorry for the delay -- the sources of debian 11 for tinker board 2s have been uploaded repo init -u https://github.com/TinkerBoard-Linux/rockchip-linux-manifest.git -b linux5.10-rk3399-debian11 repo sync

hello @wahaha, looks like the driver isn't initialised, please try: sudo modprobe 8822ce uname -a

hello @wahaha, not sure if it's a hardware or driver issue, to get a little further: 1. what is the image version you're using? is it debian 11 v.3.0.6? 2. what are the results when you execute the commands: ifconfig -a sudo lspci sudo lsmod

hello @aki, the @800000000Hz here means the gpu frequency is set to 800mhz, 0 means the gpu usage = 0 is the gpu governor set to performance? and please use these commands to check gpu when you're running applications that might be using gpu to accelerate -- for exmaple, you can use the commands while running glmark2-es2 and the gpu usage should not be 0. if the apis you are using support gpu accelerating then it (gpu usage = 0) should not be the case

hello @aki, the embedded gpu uses GLES instead of GL please use the commands below to check the gpu loading/ usage instead of glxinfo: cat /sys/devices/platform/ff9a0000.gpu/utilisation cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/load

hello @wahaha, we'll upload the codes by the end of this week, i'll leave a comment with the url once it's done. sorry for the inconvenience.
