i.MX 8M Plus : Black level correction (BLC) unable to perform

[malikshubham19]

Hi,

1. We are trying to do BLC on os08a20. Captured images as per instruction but getting very different values as compared to the sample sensor images we have. It's not under 64. Can please suggest if something wrong in this.

Please help check below attached screenshot.

2. Also, how to enable the BLC function on this os08a20 sensor ? It is written in steps.

Hello,

The os08a20 is not supported by the kernel since there is no driver on it, at least if you work with nxp bsp, so please add your driver or module and you will get the blc control all right

Hi,

We have done the procedures mentioned in AN13712 8MP_ISP_OS08A20_Sensor.pdf related to building kernel, isp-imx, isp-vvcam, storing useful .dtb and .ko files to board, added Sensor0_Entry.cfg, enabled isp and camera on board step. Could you please help tell, what specifics we need to do more ?

Hello,

Then building again the project for 6.1.22 kernel looks like the model just work for this version.
