1.6. AD Calibration Test
N/A
As SoC as built-in A/D self-
calibration mechanism, there’s not any ADC to perform.
1.7. DDC & EDID & T-Link Test
The E-EDID data structures are according to VESA Enhanced EDID 1.4a (and EIA/CEA-861B for HDMI)..
All VGA and HDMI structures have their own BIN profile which are part of firmware and uploaded at power-on.
For EDID check, it’s recommended to check whether the correct EDID is uploaded by checking corresponding
EDID NVM Checksum or read them out to check bit by bit if it is in line with the released EDID bin file.
1.8. HDCP Upgrade and Test
See Appendix
