  Hi Team,

  I want to use Luckfox Lyra zero W with Waveshare DSI display(7inch).

  I am using Luckfox Lyra zero W (512MBRAM + 256MB Flash) .
  The display being used is https://www.waveshare.com/7-dsi-touch-c ... CVJvtgck42

  I downloaded Luckfox_Lyra_SDK_250815.tar.gz (MD5: 31eda4bce0f5b0607b7368c270f287b9) from the official Google Drive.

  After extracting the archive, it contains only the .repo directory and no checked-out source tree (buildroot, kernel, u-boot, device, tools, build.sh, etc.).

  I found a forum post stating that the SDK should be unpacked using:

  .repo/repo/repo sync -l

  However, this does not work because the embedded repo is too old and fails with Python compatibility errors.

  On Ubuntu 22.04, I get:

  ModuleNotFoundError: No module named 'formatter'

  On Ubuntu 24.04, I get:

  ModuleNotFoundError: No module named 'imp'

  I also tried using the latest official repo launcher from Google:

  ~/bin/repo sync -l

  but it still invokes the embedded .repo/repo and produces the same error.

  Could you please advise:

  What is the correct procedure to unpack Luckfox_Lyra_SDK_250815.tar.gz?
  Is there an updated repo directory or a newer SDK package?
  Has anyone successfully unpacked this SDK on Ubuntu 22.04 or Ubuntu 24.04?

  Thank you.
