basler camera with 4k resolution on IMX8MP EVK android

[darsh_dev]

Hi,

I am able to get basler camera daA3840 on IMX8MP EVK with Android. Android bsp package have .drv for basler camera for 1080P resolution only. daA3840 also have support for 4K resolution which is working in Linux BSP but not on android as .drv, xml and json is not available in android BSP for 4k resolution of basler camera.

Could you please help us from where we can .drv (similar to vendor/nxp/fsl-proprietary/isp/lib64/DAA3840_30MC_1080P.drv) of basler camera for 4K resolution? I tried using .drv from linux BSP but that is not working.

Thanks in advance.

Hi,

According to "i.MX 8M Plus Applications Processor Reference Manual, Rev. 1, 06/2021", "Section 13.1.2 Display Interface", out of three LCDIF controllers one drives HDMI Tx and it supports up to 4kp30. In same section, it is mentioned that "The chip supports a HDMI 2.0a Tx interface (controller and PHY). It supports a maximum resolution upto 4Kp30"

Also, as per section 13.1.5 Image Signal Processor (ISP) "Table 13-1 Supported Resolution and Formats - 1 ISP", 4k resolution is supported.

As per section 13.1.6 Dewrap Engine, Dewrap supports one camera up to 4K at 30 fps.

In fact, basler camera with 4k resolution is working with Linux BSP. If you check  https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/isp-imx-4.2.2.13.0.bin, in that .drv for basler camera with 4k resolution is there. Which is working with Linux BSP but not android. When I use same .drv with Andorid, I see below trace where isp_media_server gets crashed.

Yes, it is working but videos encode or decode it won't work at 4k, and the lcd neither.
