Steps

  1. 1The A12 is an RK3128 arcade unit that boots its Linux OS from the spring-loaded TF (microSD) card on the back.
  2. 2There is no built-in online updater, so updating means re-imaging that TF card on a PC.
  3. 3Power off, press in the TF card to eject it, and read it in a PC with a microSD adapter.
  4. 4Back up the card with Win32 Disk Imager first, then write the newer image with balenaEtcher.
  5. 5Re-insert the TF card, power on, and let the first boot finish expanding the filesystem.

The Powkiddy A12 runs a Rockchip RK3128 with its Linux system on the removable TF (microSD) card, so a firmware update is really a re-image of that card. There is no over-the-air updater. Power off, eject the spring-loaded card from the back, and on a PC back it up with Win32 Disk Imager before writing a newer image with balenaEtcher. Re-insert and boot; the first start takes about a minute while the filesystem expands. Keep a backup so you can always return to the build you had.

FAQ

Does the A12 update over Wi-Fi?
No. The stock build has no online updater. Updates mean re-imaging the TF card on a PC with balenaEtcher, ideally after a Win32 Disk Imager backup.
Where is the card I need to re-flash?
It is the spring-loaded TF (microSD) card on the back of the unit. Press it in to eject, then read it with a microSD adapter on your PC.
