Notes and version constraints

  • The refresh time of 25 s is based on test data; actual results may vary
  • A flickering effect occurs during global refresh – this is normal
  • The text-to-image test model will be discontinued; users must configure their own model
  • No technical support is provided for the open conversion tool
  • Before swapping the TF card, shut down via PWR (hold 5 s) and disconnect USB
  • Download mode: hold PWR for 5 s, then press BOOT and click PWR
  • The specified firmware start address 0x0 is a fixed setting; changes require manual adjustment
