AM625: Offline Yocto build Issue

Part Number: AM625

Dear Expert

Sorry, I am not very familiar w/ Yocto build, so I post customer's question directlly.

I got build errors. Please see the description shown below:

1. I could build successfully with enabling network according to the guidance from TI official website. (This case would download from repositories on various websites)
2. I ran into a build fail with offline Yocto build. Here is what I did for an offline Yocto build.

B.1 I created a local repository in our Gitlab server.

B.2 To push the following directories to our Gitlab, which had been obtained in the successful one mentioned above A:

“sources”, “downloads”, “sstate-cache”

B.3 To verify if offline Yocto build was successful, I turned off the network, including Wi-Fi and Wired connection.

The result ended up with build errors.

Here are the build errors I encountered:

The following is the build command I have been using:

$ MACINE=am62xx-evm bitbake -k tisdk-default-image

In addition, I googled the solution for the build errors, finding the discussion shown below.

However, it didn’t give a total solution.

I pasted the setting for build/conf/local.conf, for your information.

Thanks.
