Critical Issue

Description

The EDID pass-through software of the DisplayPort design example does not support EDID with more than one extension block. If the DisplayPort sink\'s EDID has more than one extension block, the EDID pass-through software is not able to forward the EDID\'s second, third, and fourth extension block to the source device.

Resolution

To work around this issue, edit the following files:

  • main.c: Increase the EDID array width to BYTE rx_edid_data [512]
  • rx_utils.c: Increase the EDID array width to BYTE data [256]

This issue is fixed in version 16.0 of the DisplayPort IP core.
