Linux/DS90UB940-Q1: ds90ub940-q1 how to open Pattern Generator test?

Thank you very much for your reply
After the following operations, I did not get the data of mipi csi2
./i2cset -f -y 0 0x2c 0x64 0x59
./i2cset -f -y 0 0x2c x65 0x04
and I see internal Timing default value 840*485
I set MIPI DDR clock 600Mhz correct ? (840*485*1.5*1.35*60*24/2=600Mhz)
what else should I set up?

Best wishes

hello

I set reg 0x64=0x15,0x65=0x04. MIPI csi2 data still cannot be obtained and CLK + CLK - also did not measure the waveform

I have a few questions

1. When 0x65=0x04, BISTC should be given high or low?

2. How much DDR clock should I receive data when using Internal Timing Values(840*485)

3. What is the FPS output by Internal Timing Default Values

4.MODE_SEL sets 2 Data lanes but reading 0x6a=0x00 means 4 Data lanes is set?

5. I want to use Analop LaunchPAD, please provide me with the profile of ds90ub947-q1 and ds90ub940-q1

Do you have any ideas to help me

Best wishes

My problem has been solved Thank you very much

Hello,

For the internal settings 840 x 485 at 60 FpS the PCLK will be used is 25MHz.
If you use 2200 x 1125 at 60 FpS, the PCLK will be 100MHz.

I would recommend you to use our EVM (or your own board) in combination with our ALP software GUI, there you have very easy Pattern generator configuration possibilities.
