Check available firmware

./pyamlboot/flash-fw firmware --board aml-s805x-ac

Output:

Available firmware for 'aml-s805x-ac' board:
  file: latest.bin
  file: u-boot-2019-04-r1.bin

  file: u-boot-2020-04-r2.bin
  file: u-boot-2020-04-r3.bin

Start flashing

In this case, we will use latest.bin which points to the latest firmware available. At the moment of writing this is u-boot-2020-04-r3.bin.

Tip

You can also check the flashing status on the HDMI output. If you do, you will be sure the flashing procedure finishes correctly.

cd pyamlboot
