SN65DSI84: trying to generate test pattern

$

Part Number:SN65DSI84

Hi I got my boards back with the SN68DSI84 on it and I was trying to configure them to generate a test pattern.  I'm putting in a 74.25Mhz reference clock, reset is high, and the 1.1V regulator is working.

I wrote the following I2C registers, the format is test2.exe 0 400 write i2c_address register_address value

So far nothing is coming out of channel A.  PLL_EN_STAT is getting set and I am writing a 0x01 to 0x09-SOFT_RESET at the very end.  Did I miss something?  The DSI bus is currently not connected.

Thank you
