You can use a USB flash drive to make your device to boot from the freshly-built OS on your network-connected host development machine. Alternatively, you can also direct your device to boot from the OS on the flash drive itself.
To prepare a USB flash drive to be a bootable disk for your device, complete the following steps:
Run the following command to set the build configuration:
fx set core.x64
Run the following command to build the fuchsia image:
Run the following command to create a zedboot key, replacing
DEVICE-PATHwith the path to your target device:
