Part Number: DS90UB954-Q1
Hi Team,
Please advise me on how to enable on-chip test pattern generator.
I set up on chip test pattern generate with the following script
and checked the CSI-2 output.
I sow SOT and Sync word, however, MIPI differential driver stayed same
State level as seen in attached screen shot.
Please let me know why valid test data do not come out for the CSI-2 port.
The EVM in my hand is old and may EQ chip on it.
The marking is
PBU954Q
BIBLND
TI 73
CLGF G4
