  2. I have no idea how active this community is, but I chose the Tinker Board 2s as a platform for one of my projects. The github repo link is dead. I managed to find a fork that was functional, but it isn't complete. Is there some other source where I can draw all of the files necessary (minus the source code for AOSP as I already have it) in order to begin developing my operating system for this board? Or should I just resort to brute force and make a blob?
  3. I've looked at other articles, but there's nothing about the settings for the Android version here. The current specifications I've gathered for I2C range from 100k to 400k, and it's also mentioned that it can be 1M, but I haven't found how to set it. I'd like to know what its minimum can be.
  4. Hello. I want to use Uart in GPIO with Tinker Board S R2.

  7. Hi all, we are using a TinkerBoard with Android. Every time we connect a USB device, a window ask us to enable USB and this setting is not remembered after the next boot. Is there a way to disable this notification? Thanks
  8. Hi, Im pretty much new to ROM development for SBCs and i would like to get some info before i start working with Tinker 2 and Android, to understand if it fits my employers requirements. What we have at the moment: Tinker Board 1, with android 6 ROM, which has linux running in a chroot environment, and communicates with it via socket communication. Admin application which has root access, can run background processes without hindrance from the system, can install/uninstall/disable packages, and remount /system folders as RW when needed. IPC available for the Linux to communicate with USB ports to communicate with a depth camera. (Maybe im missing some things, but those are the main features that currently in use.) Now we need to upgrade the system to Tinker Board 2 with Android 10 and i need to know if its possible to port all the things we used on previous board, and make them work the same on the new board with an updated OS. I am aware of the changes that the Admin application will have to undergo when moving from Android 6 to Android 10, but since i dont have any experience with SBCs and embedded systems, i am more worried about the Linux/Hardware parts... Some questions are probably too simple or not related, but ill ask anyway... : What are the options that are enabled in the official android 10 rom? Do we have root access? Can we grant apps root access? Is the file system RW enabled? If there is a spec sheet id be happy if someone points me to it. And lastly, is it possible for me to take the open source in github and compile a fully custom ROM image based on the official ROM? if so, id be happy to get some info on how to do that.. Is there an active support channel for development with the Android ROM currently available ? Thanks in advance for all the answers and support.
  9. To monitor and adjust CPU/GPU frequency, board temperature, and loading status, Easy Setup Tool for Tinker Board 2 series provides the possibility to modify settings and optimize thermal performance. Below are the SOP to configure power management under Debian and Android on Tinker Board 2 series: Debian 1. Open a terminal in full screen mode and run the following command: tinker-power-management 2. Adjust CPU Governor: a. Press 'C' to open the menu. There are 4 options to select: "auto", "manual", "powersave", and "performance". b. Use the left or right arrow key to select. Option selected is shown in bold. Press the space bar to confirm, or press 'q' to cancel. 3. Adjust CPU frequency: a. Follow Step 2 above to adjust CPU Governor to "manual" b. When CPU Governor = manual, options for CPU frequency adjustment will be highlighted. There are 4 options: "min.freq for A53", "max.freq for A53", "min.freq for A72", and "max.freq for A72". Use the arrow keys to select. Option selected is shown in bold. Press the space bar to confirm and open the selected CPU frequency menu. # Follow step 2. to adjust CPU Governor. c. Once the frequency menu is shown Use the left or right arrow key to select. Option selected is shown in bold. Press the space bar to confirm, or press 'Q' to cancel. # CPU frequency menu needs to be confirmed or closed before adjusting CPU Governor. 4. Press "Ctrl" + "C" to exit Tinker Power Management anytime. Android Run adb boot first, then set CPU/GPU frequency through below command: CPU Check CPU frequency (Little core) adb shell cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq Check CPU frequency (Big core) adb shell cat /sys/devices/system/cpu/cpu4/cpufreq/cpuinfo_cur_freq Set CPU maximum frequency (Big core 2GHz/Little core 1.5GHz) adb shell 'echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' adb shell 'echo performance > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor' Set CPU minimum frequency (408MHz) adb shell 'echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor' adb shell 'echo powersave > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor' GPU Check GPU frequency adb shell cat /sys/class/devfreq/ff9a0000.gpu/cur_freq Set GPU maximum frequency (800MHz) adb shell 'echo performance > /sys/class/devfreq/ff9a0000.gpu/governor' Set GPU minimum frequency (200MHz) adb shell 'echo powersave > /sys/class/devfreq/ff9a0000.gpu/governor' tinker-power-management_SOP_EN.txt
