MIPI CSI Init Error

We have designed our own cypress CX3 board to interface with our camera sensor. The design is based on E-Con CX3 Denebola development kit.

We are getting error code 0x45 (CY_U3P_ERROR_TIMEOUT) when calling function CyU3PMipicsiInit ( void ). The same firmware works with ECon CX3 Denebola development kit. Can you please help identify the issue.

Thanks,

KN
