Other Parts Discussed in Thread: TDA4VH
Dear experts,
I use psdk_rtos_sdk_08_02_02_04 to develop TDA4VH software.
We had the same problem as this thread, https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1026164/tda4vm-csi-rx-lane-speed-setting
We are trying to bring up 2 8M cameras in CSI1, but when we follow the default configuration(in Csirx_initDPhyCfg(), psmClkFreqDiv=0x53, leftLaneBandSpeed=CSIRX_LANE_BAND_SPEED_1350_TO_1500_MBPS, bandGapTimerVal=0x14), we cannot receive the complete image of the two cameras.
Then we try to change leftLaneBandSpeed and rightLaneBandSpeed to CSIRX_LANE_BAND_SPEED_2250_TO_2500_MBPS, but still not normal.
1. when the LaneBandSpeed is changed to CSIRX_LANE_BAND_SPEED_2250_TO_2500_MBPS, do psmClkFreqDiv and bandGapTimerVal still need to be modified?
From the datasheet of TDA4VH, I didn't find out how to modify these two parameters.
2. I know from the thread https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1026164/tda4vm-csi-rx-lane-speed-setting that deserializer should send deskew calibration sequence at the very start to calibrate the CLK-DAT skew.
Can this solve our problem?
In this case, is there any modification to the csirx driver?
BR,
subin
