Hi, please follow the X1300-v1.0_software tutorial for troubleshooting:

①Check if the hardware driver is enabled

→ Refer to tutorial Section 1.1: Enable the device tree overlay in /boot/firmware/config.txt

②Verify EDID checksum validation

→ Refer to tutorial Sections 1.4–1.5: Create an EDID text file & load the EDID data

③Confirm the correct media device node

→ Refer to tutorial Section 1.8 Reset links: The /dev/media number may vary; check it via Step 1.3

④Ensure the CSI link is properly bound

→ Refer to tutorial Section 1.9 Set formats

⑤Keep the full-link video format consistent

→ Refer to tutorial Section 2.0 Set output formats

NOTE:

• Critical: Double-check that the media device node matches. /dev/media2 in the tutorial is only an example. Run v4l2-ctl --list-devices first to find your actual media number (use 0 if you previously used /dev/media0).

• Do NOT skip the EDID checksum fix. The tutorial includes --fix-edid-checksums; omitting this parameter will break EDID functionality, which is a major cause of the error.
