After this we can load the Linux image:
grlib> load images/image.dsu

section: .vmlinux at 0x40004000, size 2782144 bytes
total size: 2792384 bytes (79.0 Mbit/s)

gr-leon4-itx login:
The above transcript loaded an image built from the the gr_l4itx_video configuration. In that
case the boot messages are passed to the graphical console. The Linux boot takes some
time and you may need to wait a minute before reaching the login prompt on the serial
console. The video output will show the boot messages as the system starts up.
If we instead load an image built from the gr_l4itx_serial configuration, all output will be
directed to the serial console:
grlib> load images/image.dsu
section: .stage2 at 0x40000000, size 10240 bytes
section: .vmlinux at 0x40004000, size 2642880 bytes
total size: 2653120 bytes (79.1 Mbit/s)
