Hi,

but now we can not make DS90UB934Q1-EVM and surrond view camera to communication and parallel data output,when we refer to <Using the DS90UB934-Q1EVM Evaluation Module>.

I had checked that PCLK signal have output and I2C communication is normal on DS90UB934Q1-EVM demo.

Hello Wenjun,

The input mode of operation is controlled by the MODE strap pin to select the mode. The input mode may also be overridden and configured by FPD3_MODE (Register 0x6D[1:0]) setting in the Port Configuration register. Can you share what your setting is?

Can you check and share these register values on the 934?

0x5B (SER_ID)

0x4C FPD3_PORT_SEL

0x4D RX_PORT_STS1

Do you want to check your FPD3 signals that the 934 receives from the SER? If so, you can use CMLOUT. Please refer to this thread: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/729803/ds90ub954-q1-how-to-set-cmlout

Best Regards,

Shruti

Hello Wenjun,

Can you please clarify what your goal is? Can you maybe please provide a block diagram?

Is your DES able to receive data from the SER?

"The CMLOUT monitors the post EQ stage, thus providing the recovered input of the deserializer signal."
