Other Parts Discussed in Thread: SN65DSI83, DSI-TUNER
I have a script I wrote that generates a test pattern using a SN65DSI83. We've since moved on to the SN65DSI85. The test pattern script no longer works and so far I haven't found what I'm missing. We're using a 74.25Mhz input clock on ref. When I run my script now nothing comes out of the part.
Here's the script

Do you see anything I've missed?
Thank you
