Hi, We have a CX3, which is operating a Sony CMOS imager and utilising the MIPI data bus. We find that the MIPI reset pad is driven high at start-up and remains that way - apparently preventing MIPI transfers. The pad has a 10K pull-down but is otherwise unconnected. Is the MIPI reset somehow configured as an output, rather than an input? We cannot find any reference to setting its state in the data sheet.
Regards,
Terry

Hi,
MIPI reset pulled-up is an expected behaviour. Please refer to the power up sequence on page 10 of the datasheet. It will be low only during the reset period and then it will be pulled up.
