Solution 1:[1]

virtual/kernel recipes in Yocto are just simple recipes like all recipes.

So, you can set your recipe source to whatever Yocto supports as source type (git, file, ...)

For your case, you can:

  • Host your custom kernel in a local private git server and use git
  • Use a local kernel compressed source file and use file

Solution 2:[2]

SRC_URI = file://xxx.tar.gz is correct.

You should not put files into the download folder, bitbake will do that when it downloads something. Put it to your source if you use file://.

If your file is not found from the default FILESPATH you can add extra directories to search using something like FILESEXTRAPATHS_prepend := "${COREBASE}/../mysrc:".

Use bitbake -e [recipe] if you are unsure where the variables point to.
