### Booting form network

|
By default DI/OT board will try to obtain from the DHCP server the IP address of the tftp server and the filename of an image. U-boot will try to retrieve the pointed image via TFTP. After the successful transfer the u-boot will try to run the retreived image as a script. If it fails, it will run as regular image.

### Create script to be used by network booting
|
|
|
|
|
|
|
|
|
|
Create text file with valid uboot commands to be executed. E.g.:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
echo "echo hello!" > boot_script.txt
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Make a uboot image out of that file:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
mkimage -A arm -O linux -C none -T script -n 'boot script' -d boot_script.txt boot_script.img
|
|
|
|
|
```
|
|
|
