Network Boot

When you are developing or debugging on your kernel or a file system application, network boot can be handy to avoid multiple flashes and to load new application versions without having to reboot the board each time.

Network boot configuration will load the kernel and device tree from n TFTP server and the root file system will be shared from host PC over NFS.

Host Setup

You will need a TFTP server and a NFS server, you can use the following instruction to set them up if you don't have them already.

TFTP and NFS Configuration

For the following steps you should have a complete Yocto build for the Nitrogen8M as described at Building Yocto

1. Copy the kernel image and the kernel device tree blob from your Yocto build into the TFTP directory.

cd $YOCTO_BUIlD_DIR/build/tmp/deploy/images/nitrogen8m
