Jetson NANO Camera connection

Hello,

I am trying to connect Camear BD DM-G15-42 to Jetson NANO,

I use BT.1120 to MIPI 4 Lane Bridge (LT9211) but NANO can’t read this camera.

I got the error message as below
CILA_CTRL_ERR: Control Error. Set when CIL-A detects LP state 01 or 10 followed by a stop state (LP11) instead of transitioning into the Escape mode or Turn Around mode (LP00)

I don’t understand this part.

And there are log msgs keep repeating as below:

1197 [80451.780882] video4linux video0: frame start syncpt timeout!0
1198 [80451.787335] vi 54080000.vi: TEGRA_CSI_PIXEL_PARSER_STATUS 0x00000000
1199 [80451.787354] vi 54080000.vi: TEGRA_CSI_CIL_STATUS 0x00000010
1200 [80451.787371] vi 54080000.vi: TEGRA_CSI_CILX_STATUS 0x00040040

Please help us with this.

You may need to make sure the sensor output timing match MIPI spec.

Can you check and confirm your sensor and bridge are turn on correctly? Please check with vendor for the methods first.

we would try to match the timing of sensor output.

we would send you more information with block diagrams.JETSON NANO CAMERA BLOCK.pptx (505.9 KB) LT9211_Datasheet_R2.1.pdf (1.5 MB) LT9211_LVDS&TTL_TO_MIPI_V1_0.pdf (120.1 KB)

as i mentioned before,

1197 [80451.780882] video4linux video0: frame start syncpt timeout!0
1198 [80451.787335] vi 54080000.vi: TEGRA_CSI_PIXEL_PARSER_STATUS 0x00000000
1199 [80451.787354] vi 54080000.vi: TEGRA_CSI_CIL_STATUS 0x00000010
1200 [80451.787371] vi 54080000.vi: TEGRA_CSI_CILX_STATUS 0x00040040

These msgs kept on coming.

Is there any problem with the bridge or any other problem?

Have a check if the sensor output continuous clocks and it been enable before the CSI/VI start capture.

Hello Shane,

Many thanks for your reply.

I would check that and retry the connection.

Thank you
