Hi: We are using JetPack 35.6 and ORIN module on our custom board. Now it fails to collect D-Phy 2.5Gbps image, which might be due to the of lack of the deskew functionality. We are now seeking your help to develop the D-Phy deskew functionality, which includs starting deskew, reading and setting …

Don’t need send it every frame ends. Can you check if able send it before the like this. [image]

What’s the speed without problem?

For Orin please using JP6.x latest release. Thanks

The version we are using is JP5.0.2, and we have flashed the RTCPU debug firmware from the link https://forums.developer.nvidia.com/t/how-to-deskew-dphy-without-serializer-deserializer/340270/17 . The camera’s data rate is 2.5 Gbps. When we set the MIPI rate to above 1.5 Gbps in the RTCPU, it prints …

The error tell the deskew calibration error. Suppose could be the sensor didn’t send the deskew word before streaming. Skew calibration is required if sensor or deserializer is using DPHY, and the output data rate is > 1.5Gbps. An initiation deskew signal should be sent by sensor or deserializer t…

Which error message indicates a deskew calibration error? [ 7095.500614] [RCE] Deskew setup message sent for port 2 num_lane 4 [ 7095.500615] [RCE] ISR PHY 1 CIL_A 0xe000000 [ 7095.500616] [RCE] ISR PHY 1 CIL_B 0x6000000 [ 7095.500617] [RCE] ISR PHY 1 CIL_A 0xe000000 [ 7095.500618] [RCE] ISR P…

Below shows the REG NVCSI_PHY_1_CILA_INTR_0_STATUS_CILA_0 status. The bit 25/26/27 tell the deskew calibration failed. [image] kenny_234: [RCE] ISR PHY 1 CIL_A 0xe000000

We confirmed that the sensor transmitted the deskew correction information before Orin start stream on. Following is the log of the sensor transmitting deskew correction information and setting the MIPI rate of the Orin RTCPU to 2.5G. [ 4876.071814] t194-nvcsi 13e40000.host1x:nvcsi@15a00000: num_…

Check the REG NVCSI_PHY_1_CILA_INTR_0_STATUS_CILA_0 in TRM for the detail. Thanks

Please confirm the deskew word send out after sensor sensor driver xxx_start_streaming() been called. Thanks

We have confirmed that the sensor has sent the deskew word before call xxx_start_streaming() . When the deskew word is not sent, the error message as below: [RCE] ISR PHY 1 CIL_A 0x10000000. When the deskew word is sent, the error messages as below: [ 4876.117784] [RCE] ISR PHY 1 CIL_A 0xe00…
