IMX8MP imx219 stair-like cuts at the picture edge

samuelschueller — Mon, 18 Nov 2024 12:53:59 GMT

Dear all,

I'am working with the ucm-im8m-plus modul from compulab which contains an NXP i.MX8M Plus. I loaded the compulab official realase image from February 19, 2024 to SB-UCMIMX8PLUS Rev 1.1 evaluation board and activated the ucm-imx8m-plus_mipi-csi1-imx219.dtb devicetree as described in the compulab wiki. I have connected a Raspberry Cam V2 with an imx219 sensor to the MIPI-CSI1 port.

- linux-compulab version 6.1.55

- isp-imx version 4.2.2.24.0

- isp-vvcam version 4.2.2.24.0

When I take a picture with the command

gst-launch-1.0 v4l2src=/dev/video2 num-buffers=1 ! 'video/x-raw,width=1920,height=1080,format=NV12' ! jpegenc ! filesink location=/tmp/single_buffer.jpg

a single image is saved, but it has these staircase-like cuts at the edge of the image and black areas at the edges. The color is also somewhat greenish.

Compulab suggests contacting NXP as they cannot help me with this type of problem.

Does anyone have any idea what causes these edges and how the problem can be solved?

Best regards

Samuel

Unfortunalty compulab could not help me and suggested to contact NXP.

Just solved the problem.

Need to disable the dewarp by setting the "bypass": true, in the sensor_dwe_imx219_1080P_config.json configuration file.
