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

1_ Writing 0xff to 0x000b solved our problem and now the CSI-2 output of the module is in HS mode not LP mode. 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.

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

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

True ?

@veye_xumm said in Veye MIPI imx462 Defaults:

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.

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.

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

UYVU or YUYV ?
25 fps or 30 fps ?

HS mode and LP mode?

Thanks.

Hi,
I'm trying to config veye_mipi_imx462.
FPGA => IMX462 (via I2C)
I had extracted i2c command list from your script.
This is a part from my command list:
I2C_ADDR ==>> 0x3b
//=========================
read_devid :
read 0x3b 0x01
//=========================

read_releasedate :
write 0x3b 0x10 0xDA
write 0x3b 0x11 0x5C
write 0x3b 0x13 0x01
sleep 0.01
yy= read 0x3b 0x14

write 0x3b  0x10 0xDA
write 0x3b  0x11 0x5D
write 0x3b  0x13 0x01
sleep 0.01
mm= read 0x3b 0x14 );

write 0x3b  0x10 0xDA
write 0x3b  0x11 0x52
write 0x3b  0x13 0x01
sleep 0.01
dd= read 0x3b  0x14

//=========================
read_hardver :

hardver= read 0x3b  0x00

//=========================
read_sensorid :

sensorid_h= read 0x3b 0x20
sensorid_l= read 0x3b 0x21
SENSOR_ID=(((sensorid_h<<8)+sensorid_l))

//=========================
read_wdrmode :
write 0x3b 0x10 0xDB
write 0x3b 0x11 0x32
write 0x3b 0x13 0x01
sleep 0.01
wdrmode= read 0x3b 0x14

write_wdrmode :
write 0x3b 0x10 0xDB
write 0x3b 0x11 0x32
write 0x3b 0x12 $PARAM1
write 0x3b 0x13 0x00

value description
0x00 Back Light Mode OFF
0x01 Back Light Mode ON, LOW
0x02 Back Light Mode ON, HIGH
0x03 DOL WDR Enable
//=========================

But I just can read device ID, and None of the commands work.

Please guide me. Are the commands I wrote above wrong?

@veye_xumm
Thanks

Dear Sir/Madam,

We are working on VEYE-MIPI-IMX462 and trying to get the video with FPGA but we couldn't receive the video as YUVY4:2:2 8bit but we receive some noisy data as RGB Video.

1_What is the actual video format?
2_What is the pixel-per-clock rate?
3_What is the Line Rate of camera?
4_Is there a sample code for XILINX FPGA to receive VEYE-MIPI-IMX462 video output?

We would appreciate it if you could help us to receive the mentioned camera video output.

Best Regards,

@nimadibaj
In all file I can just see imx307 & 327 & CS & mv & in raspberry and Jetson DTS and ....
Why??
What is I2C address for veye imx462??
