Step to build yocto linux with GUI on imx8mmevk

[hhm95]

Hi everyone! I am new member. I have a problem when build with my device imx8mmevk.
First, I build successfully with: bitbake core-image-minimal and booted successfully.

Now, I want include a GUI, so I run with: bitbake imx-image-multimedia,

My error:

"ERROR: opencv-4.1.2.imx-r0 do_fetch: Fetcher failure: Unable to find revision c5bf3ec2e791e0817ab1d5880e78711b6fe08206 in branch 4.1.2_imx even from upstream

My question: Am I missing the opencv setting? I read this post and download opencv-extra from this link, but I don't know where to put this folder.

Have a nice day!

Hello hhm95,

Apparently the 4.1.2v has a wrong package and its not supported by opencv in MX8MM, please try the opencv that yocto itself provides.

Hi, thanks so much for your reply

I think, I am using opencv 4.1.2 that yocto itself provides, and it not support on imx8mm.

So, Can I change version opencv?  Or how to fix this error on imx8mm to build.

Have a nice day!
