# imagebuilder
## `Dockerfile.image`
```
$ cd imagebuilder
$ docker build --force-rm --file Dockerfile.image -t imagebuilder .
```
## `/imagebuilder_sd` or `/imagebuilder_tftp`
### TFTP
Run the following command to generate a uboot script to tftp all the
necessary binaries automatically:
```
$ docker run --rm --privileged=true -ti -v /tmp:/tmp -v /dev:/dev imagebuilder /imagebuilder_tftp
```
The generated files are in `/tmp/output`. At the u-boot prompt run:
```
tftpb 0xc00000 boot.scr; source 0xc00000
```
If you are using QEMU, you also need to manually setup the ip address.
Run this command instead:
```
setenv serverip 192.168.76.2; tftpb 0xc00000 boot.scr; source 0xc00000
```
### SATA
Run the following command to generate an image to be written on disk:
```
$ docker run --rm --privileged=true -ti -v /tmp:/tmp -v /dev:/dev imagebuilder /imagebuilder_sd
```
The generated image is `/tmp/img/zynqmp.img`. Proceed to dd it to a
disk, or pass the file as an argument to QEMU (describing how to use
QEMU to emulate a SATA disk is out of scope for this document).
At the u-boot prompt you can boot automatically with the following
command:
```
scsi scan; load scsi 0:1 0xc00000 boot.scr; source 0xc00000
```
