Hello, I encountered some HDMI display issues when using Thor on the R38.4 version. Based on my own carrier board, HDMI uses DP0. After the system starts, the screen is unable to display.
My current basic information:
Used version: R38.4
Schematic diagram:
Status：
I found that during the system startup, hotplug was not utilized at all, but instead, it simply returned.
None of the PF.03 pins were used. I checked that the PF.03 pin was set as an input, and verified that when the HDMI interface was inserted, PF.03 was 0, and after the HDMI interface was removed, PF.03 was 1. This indicates that the logic is correct.
Could you please help me figure out which aspect of the problem is causing the HDMI to not display? Thank you.
