Error CameraService: connectHelper: Could not initialize client from HAL

I'm currently having trouble getting a valid image from my camera. I'm currently using Android 8, with a verified device driver (We've used this driver with a different IMX6 board/kernel in the past). When I try to open my camera application (also verified with old board/kernel) I get the following in logcat:

I have some simplified camera code which behaves the same it looks like this :

try{
 mCamera = Camera.open();
 Camera.Parameters params;
 params = mCamera.getParameters();
 params.setPreviewSize(1920,1080); mCamera.setPreviewDisplay(sSurfaceHolder); mCamera.startPreview();
 } catch(Exception up) {
 Log.e(TAG, "Camera didn't start! :" + up.getMessage());
 }

‍‍‍‍‍‍‍‍‍

I've also tried the native android camera application, which gives the same error. However, it tries to open the camera again by forcing some settings which does display an image. However the image is broken like so:

The image is supposed to be a test image (standard color bars) from the image sensor. It looks like the rows are all messed up. Which makes me believe the default camera app may be guessing at the row count?

I've also checked all the mipi and ipu registers I thought were relevant.

NUMBER OF ACTIVE DATA LANES 3
 PHY SHUTDOWN CONTROL 1
 PHY RESET 1
 CSI2 CONTROL RESET 1
 GENERAL SETTINGS FOR ALL BLOCKS 300
 DATA IDS FOR WHICH IDI REPORTS LINE BOUNDARY MATCHING ERRORS 0
 DATA IDS FOR WHICH IDI REPORTS LINE BOUNDARY MATCHING ERRORS 0
 ERROR STATE REGISTER 1 0
 ERROR STATE REGISTER 2 0
 MASKS FOR ERRORS 1 0
 MASKS FOR ERRORS 2 0
 D-PHY TEST INTERFACE CTRL 0 0
 D-PHY TEST INTERFACE CTRL 1 0
 IPU REGISTERS :
 CONFIGURATION OF IPU_CONF 10000660
 INTERUPT STATUS 1 IPU_INT_STAT_1 800000
 CSI0 DATA IDENTIFIER IPU1_CSI0_DI ffffff1e
 CSI0 SENSOR CONFIGURATION IPU1_CSI0_SENS_CONF 4008900
 CSI0 SENSE FRAME SIZE IPU1_CSI0_SENS_FRM_SIZE 437077f
 CSI0 ACTUAL FRAME SIZE IPU1_CSI0_ACT_FRM_SIZE 437077f‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

1E is the correct MIPI type, however is "ffffff1E" correct? Should it be "1E1E1E1E"? Or something else? The image is a 1920x1080@30 stream using 4 lanes. From what I can tell this is correct output from the Mipi and IPU registers.

My DTS file regarding the mipi looks like this :

/{
 v4l2_cap_1 {
 compatible = "fsl,imx6q-v4l2-capture";
 ipu_id = <0>;
 csi_id = <0>;
 mclk_source = <0>;
 status = "okay";
 };
 v4l2_out {
 compatible = "fsl,mxc_v4l2_output";
 status = "okay";
 };
};‍‍‍‍‍‍‍‍‍‍‍‍‍

&mipi_csi {
 status = "okay";
 ipu_id = <0>;
 csi_id = <0>;
 v_channel = <0>;
 lanes = <4>;
};‍‍‍‍‍‍‍

I feel like something is missing in my kernel which is necessary for android to know the parameters of my camera. However, I can't seem to figure out what that is. I've read through and performed the actions in the "Debug steps for customer MIPI sensor" document, with no luck. Any help would be greatly appreciated!

Thanks, and please let me know if more information would be useful.

Hello Anthony,

You are using MX6Q? the you have a none supported camera mode.
