what is the meaning of "state is both 0x300 and 0x620 jump"?
can you measure the CSI2 clock output of UB940?

best regards,
Steven

0x300 and 0x620 is IMX6DQRM.PDF(page3557) MIPI_CSI_PHY_STATE value . I hope this value is 0x330 or 0xb30 mean Data Lane 0/1 in stop state

I measure the CSI2 clock output is 33khz

the CSI clock is 33KHz? it is not correct.
pls make sure the UB940's mode setting is correct to match the CSI2 I/f setting.

Steven
