Hi there,

I’m using the Genio 510 EVK with NDA_BUILD="1". Since one of our products does not use the camera ISP feature, I want to remove the mtk-camisp-prebuilts package to optimize the image size.

Could you please provide:

  • The standard procedure to disable/remove this package in the Yocto environment.
  • Whether this removal affects other system stability.

Thanks in advance for your help!

Hi @andrew.hess ,

Regarding the mtk-camisp-prebuilts package, it is only mandatory if your application requires hardware-level RAW sensor + ISP processing.

For applications using the YUV sensor + pure data dump, you only need to ensure that mtk-camisp-driver is present in the system. The prebuilt binaries can be removed without affecting others.

To disable the automatic installation of these packages under NDA_BUILD=1, please modify the RITY package group as follows:

File: meta-rity/recipes-rity/packagegroups/packagegroup-rity-mtk-camisp.bb

diff --git a/meta/recipes-rity/packagegroups/packagegroup-rity-mtk-camisp.bb b/meta/recipes-rity/packagegroups/packagegroup-rity-mtk-camisp.bb

This modification will prevent the ISP prebuilts from being included in your image. If you encounter any unexpected behavior during validation, feel free to reach out.
