We made an adaptor board to connect our camera board to HDK8450, and the channel length is about 25cm. The CPHY speed requirement is 4Gsps.
We use MIPI CSI0/CSI1/CSI2 interface of HDK8450.
Would you please help to tell us which register is to set these CSI CPHYs EQ strength?
Sorry for that but adding a new camera module needs to compile the driver code on top of Qualcomm release, and MIPI connection details should be covered by the customer document. Unfortunately, the code and document is only valid to a licensed customer but not visible at QDN.
If you really need it, suggest you to contact with Qualcomm business team and get the support from customer support channel.
