Hi NXP,
In the RT 1170 EVK with the OV5640 camera 1920 x 1080 is streaming perfectly without any issue but when we use other cameras instead of the default OV5640. We could see tearing issue on the LCD display of the EVK itself.
Conditions :
1. Used the SDK example evkmimxrt1170_csi_mipi_yuv_cm7.
2. Streaming cameras other than OV5640 with camera output format YUV422 by changing the MIPI clock and THs settle values.
3. For lower FPS lesser than 10 I'm not facing any issue but I need to stream 30 FPS.
4. MCUXpresso 11.9.1 and SDK 2.16
Any help regarding this issue would be appreciated.
Regards,
Ragnar.
Hi @EdwinHz ,
Thanks for the confirmation.

Ragnar.
Hi @Ragnar,
I was erroneous on my previous reply.
WXGA @60 fps is only possible without rotation and scaling transformations.
I apologize for the confusion.

Hi @EdwinHz ,
Thanks for the information. Will it support WXGA resolution @60 fps. Even with the rotation and scaling enabled.
Regards,
Ragnar.
Hi @Ragnar,
The RT1170 can support up to WXGA resolution @60 fps.
Hi @EdwinHz ,
I have gone through the i.MX 8/RT MIPI DSI/CSI-2 AN and still I'm facing the same issue.
Yes I have tried "csi_mipi_rgb_cm7" here also I'm getting the same issue. The same issue is memtioned in this thread https://community.nxp.com/t5/i-MX-RT/Camera-image-glitching-tearing-when-DEMO-CAMERA-BUFFER-COUNT-3/....
May I know what is the maximum RESOLUTION and FPS that RT1170 supports.
Thanks & Regards,
Ragnar.
Hi @Ragnar,
Firstly, I would like to recommend you follow the specifications that are described on the following application note: i.MX 8/RT MIPI DSI/CSI-2. Especially the CSI side, since the issue seems to be coming from the different cameras, not the display.
What other cameras are you trying? Does this also happen with "csi_mipi_rgb_cm7" example code?
BR,
Edwin.
