Yocto linux build for de SC206E

Hello again

after lets say i succesfully get the full_update_ext4.zip and update.sig files using the provided OTA scripts. Please still answer the question about the bitbake OTA files

However, on my SC206E EVB, ADB is not available or is not functioning correctly, so I cannot push files via adb push.

I would like to ask:

  1. What is the correct method to update the system using full_update_ext4.zip from an SD card?
  2. Is update_engine included in the default system image? On my device, the update_engine binary is not found, and I can’t proceed with the OTA update.
  3. Are there other alternatives to apply the update via UART or directly from the SD card?

Any help or official guidance would be appreciated.

Best regards,
