  1. Hi, I am facing issue while rebooting device takes, it takes more than 1.50-2.50min while using sudo reboot command & through GUI reboot also. Does anyone face this issue are anyone have idea about this issue. Please suggest any solutions.
  2. I am currently working on the Tinker Board project (Application that using GUI). Recently, I had to replace the Tinker Board logo with our product's logo on kernal that I have cloned from github. I followed the instructions mentioned in Developer Guide · TinkerBoard/TinkerBoard Wiki (github.com) However, I am not sure if the kernel image that I compiled from TinkerBoard2/kernel (github.com) is optimized for Debian. Can you confirm if it is optimized and compatible with Debian? Or suggestion the step to make it work
  3. Hello i am trying to port the mainline debian 11 img to the tinkeredge R and i was hoping if anyone here knew what firmware packages and drivers and required to get it to boot
  4. I tested ufw and nftables on the latest release. But no luck. Tinker Board 2 team, could you please tell me how to enable firewall on this OS? Using ufw After adding a simple rule to ufw, I got the following error when I enabled it. linaro@linaro-alip:/lib/modules/4.4.194$ sudo ufw enable Command may disrupt existing ssh connections.

  5. Hi, I built the kernel in Debian 10, on Tinkerboard 2S. I got these 3 errors. Do they need patches? make[4]: *** [scripts/Makefile.build:484: drivers/net/wireless/rockchip_wlan] Error 2 make[3]: *** [scripts/Makefile.build:484: drivers/net/wireless] Error 2 make[2]: *** [scripts/Makefile.build:484: drivers/net] Error 2 make[1]: *** [Makefile:1036: drivers] Error 2 make: *** [arch/arm64/Makefile:169: kernel.img] Error 2 make: *** Deleting file 'kernel.img'
  6. I like the idea that the TinkerOS is specifically designed and optimized for the TinkerBoard, but it includes quite a bit of fluff and I'd like to start from a clean CLI Debian install. Is there a detailed list of differences TinkerOS has over Debian, so I could include the optimizations and adjustments in the configurations but without all the unneccessary (to me) packages? I would just download Debian and diff the whole tree against TinkerOS, but the problem is TinkerOS comes already "installed" so the way the image itself is set up is completely different from any of the ways Debian is distributed. It also feels kinda brutish. Thanks
  7. Hello, I'm using the tinker board 2s when I used raspberry Pi, I made the entire SD card Data into an image file and backed it up. However, in the case of tinker board 2s, when OS is installed, the partition is divided into several parts, and when sd card is inserted into the PC, the data on the SD card cannot be accessed. How can I backup the Tinker board?
  8. 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
  9. Hello, As the ASUS Tinker Board has so many wonderful features and direct access of lower level peripherals, I've decided to migrate my development from raspberry Pi to Tinker board. Right now, I'm starting with a basic UART code which sends and receive some strings serially but unfortunately it is not working as expected. The UART I'm trying to use UART1 (Pin number 8 and 10). Right now, if (serialDataAvail(fd)) is getting true every single time. After reading the data serialGetchar(fd), I found out that, the RX pin is in low state (receiving 255 continuously). Although, my code has no error, but I'll still add it here. #include <stdio.h> #include <string.h> #include <errno.h> #include <wiringPi.h> #include <wiringSerial.h> int main () { int fd,inCount = 0 ; char inBuff[500],OutBuff[500]; if (wiringPiSetup () == -1) { fprintf (stdout, "Unable to start wiringPi: %s\n", strerror (errno)) ; return 1 ; } else printf("wiringPi: init successfull! \n\r"); if((fd = serialOpen ("/dev/ttyS0", 115200)) < 0) { fprintf (stderr, "Unable to open serial device: %s\n", strerror (errno)) ; return 1 ; } else printf("Serila: /dev/ttyS0 successfully opened! \n\r"); while (1) { if (serialDataAvail(fd)) { inBuff[inCount] = serialGetchar(fd); if ( inBuff[inCount] == '\n') { printf("RX String=%s"); memset(inBuff,'\0',inCount); inCount = 0 ; } inCount++; if ( inCount == 500) { inCount = 0; memset(inBuff,'\0',inCount); } } } } The reply of "dmesg | grep tty" is attached below.
