Drive strength setting for CSI Port1

Hi,

3

We have designed one custom board based on iMX8M SOC.In this we are using camera(OV5640) mezzanine from D3 engineering.We are planning pre-compliance testing for this custom board and observed that CSI port1 differential clock is radiating.For termination settings of this clcok we are following IMX8MDQLQRM reference manual Rev. 1, 04/2019. and we found that there is no General Purpose Register information for CSI1 port.This detailed information is given for CSI2 port(Section 8.2.4.35 GPR34 General Purpose Register (IOMUXC_GPR_GPR34) ).Is there any way/Document to change termination value of CSI1 port?

Regards,

Sandeep

Hi Sandeep

there is no "CSI1 port", there are two MIPI CSI2 ports :

section 8.2.4.35 gives description of CSI2_1_RX_RCAL

CSI2_2_RX_RCAL is described in sect.8.2.4.42 GPR41 General Purpose Register (IOMUXC_GPR_GPR41)

Best regards
igor
