DS90UB953-Q1: SCCB registers reading throug USB2ANY interface

Part Number: DS90UB953-Q1
Other Parts Discussed in Thread: ALP

Hello

I have a 954/953 system connected to the image sensor OV2775 and I wou|d like to read the registers from the sensor. Right now thanks to the 954/953 bring up guide I was able to configure the sensor and receive the CSI output, however I would like to read the registers in the ALP interface, but they always are 0. It seems I can only write but not read. Does this have anything to do with the difference between the I2C and the SCCB interface? Thank you! 

Regards

Natalia

    Hello Natalia,

    using the ALP interface you can write 8-bit and 16-bit addresses but you can read only 8-bit addresses. so it is not possible to read the Sensor's registers.

    to do that you need to use another debugging tool as Aardwark and their interface.
