      Hi,
      What is the default config of veye mipi 462 ?

      UYVU or YUYV ?
      25 fps or 30 fps ?

      HS mode and LP mode?

      Thanks.

        We are analyzing the output signal. It seems that between each video line, the CSI-2 output from your module enters Low-Power (LP) mode, which causes the video stream to continuously drop in and out. The module is completely new, and we have not sent any I²C commands to it. It appears that the module should operate in High-Speed (HS) mode, but it does not.

          This complies with the MIPI CSI-2 standard.

            Yes, you are right. The output of this module is MIPI standard. But we want to change its output mode. The ISP chip used in this module is currently working in LP mode (discontinuous clock mode). We want to change its mode to HS (continuous clock mode). Just give us the corresponding I2C command.

              Use the i2c_write command to change 0x000b to 0xff.

                Sorry, I don't understand. I should write 0xff to this address : 0x000b.

                True ?

                  I don't know which platform your motherboard is using, but if you have used the veye_mipi_i2c.sh script, there is an i2c_write file in that directory. You can use this file to modify the aforementioned registers.

                    Hello my friend.
                    We are sending I2C commands via a FPGA.

                    1_ Writing 0xff to 0x000b solved our problem. Thank you. Please give us a command to save this change.

                    2_ We are trying to change video frame rate (now is 30fps and we need 25fps).
                    by these commands we cannot do this :
                    0x10 0xDE
                    0x11 0xC2
                    0x12 0x00
                    0x13 0x00
                    (sending Two byte, then sending next two byte and ... ).

                    Please guide me. Thanks a lot.
