How do I resolve the USER_FIFO_OVERFLOW interrupts (
0x110) when I am using
the DisplayPort in Receiver mode?
This is caused when the incoming DisplayPort data stream on the
lnk_clk domain is too fast compared to the outgoing data stream
There are two ways to resolve this:
- If possible, increase HBLANK from the source.
- Increase the
rx_vid_clkfrequency to the maximum tested of 300 MHz.
- Check whether the subsystem is generated with the appropriate color depth (bits per color) to be able to properly receive the pixels from the source.
