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 1.3 (and EIA/CEA-861B for HDMI). CEA Timing
Extension structure has been extended to support all 3D capable timings.
All HDMI structures have their own BIN profile which are part of main SW and uploaded at power-on into soc chipset:
For EDID check, it’s needed to check whether the correct EDID is downloaded 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 Test
For HDCP compliancy, it’s needed to check whether the HDCP key has been well set by connecting suitable
