#U boot linux code
Using this method Yocto will take the source code from your own remote repository on github:Ĭreate your own github account and upload your proprietary U-Boot to a new repository:įor example, you can fork our repository to your own account by visiting the following link and clicking on "Fork" at the top right of the screen.Īlternatively, you can clone our repository to your local machine, and push it later to your own account. (If you do so, make sure to run " bitbake -c cleansstate virtual/bootloader" before rebuilding U-Boot) 3 Use your own remote repository on github UBOOT_SRC = "git://$" during development to get the latest commit of the branch

Update the recipes to use the local repository instead of the default one:Īnd append the following lines to it (see the previous section for listing the commits or getting the latest commit id): $ git commit -a -m "my_m圆var_som_changes" Make your changes in the source code and commit them:Īfter making changes in the source code you need to commit them. Using this method Yocto will take the U-Boot source from a local repository instead of our remote ones on github: $ cp u-boot-variscite.bbappend u-boot-fw-utils.bbappend
