Tinkerboard / S

  • Severe powering troubles due to Micro USB power connector. It’s recommended to power through GPIO pins to prevent under-voltage issues (instabilities, boot/crash cycles). Powering situation is a little improved/masked on model S.
  • serial console is enabled on UART2 (pin 32, 33, 34=gnd)
  • eMMC flashing (model Tinkerboard S with eMMC) can be done the same way as burning an SD card. Connect your board with USB cable to your computer (Linux or Windows) and eMMC will be seen as a new hard drive. Burn an image to this drive. Wait until it's done, detach from computer and power with your normal PSU.
  • booting from SD card on S model is possible in Maskrom mode.

Debian Bookworm 24.8.1 minimal testing:

  • Boot ok, from sdcard and eMMC
  • HDMI is ok
  • USB2 ports are ok
  • Gigabit Etherner is ok, troughput ~940Mbit/s
  • Wireless ok, (stable but slow, ~5Mbps/s but router is far away as well)
  • Analog audio codec does not work
  • Reboot and shutdown work as intended

Ubuntu Noble 24.8.1 XFCE testing:

  • Boot ok from sdcard and eMMC
  • HDMI is ok
  • USB2 ports are ok
  • Gigabit ethernet ok
  • Wireless ok, inglorius performances as Debian
  • Bluetooth works
  • Analog audio codec work
  • Reboot and shutdown work as intended

To boot the image from USB flash:

  • Write the image to a USB flash drive
  • Insert the flash drive into the USB3.0 port
  • Load the modified u-boot (from the Armbian image) using the UART method
  • Stop the default boot sequence
  • Execute in u-boot prompt: run usbboot

To flash the image to eMMC:

  • Boot the image from USB flash
  • Write the image to eMMC using dd or other methods
  • Mount the eMMC partition and add a line emmc_fix=on to /boot/armbianEnv.txt file – this changes the DT during boot to switch from SD with card detect switch to a non-removable eMMC.
  • Unmount the eMMC partition and reboot

Please refer to this forum thread for the USB boot details and this thread for a discussion of known eMMC issues.
