This is a collection of scripts used to build an image file that can then be transferred to a SD Card using `dd`.
This is a collection of scripts used to build the MNT Reform System Images, which are based on Debian GNU/Linux. The images can be transferred to an SD card and booted by an MNT Reform computer.
## Downloading and Flashing a System Image
Most users will want to download a pre-built image from: https://mnt.re/system-image
1. From the link above, download the file whose name matches the Processor Module in your MNT Reform:
2. Unzip the image using `gunzip reform-system-imx8mq.img.gz` (Substitute your actual image file name, also in the following steps)
3. Identify the device name of your SD card. For example, you can check the output of `lsblk` before and after you insert the card and compare which new device appears. Below we use the device `sdx`, but it will probably be a different one on your computer.
4. Copy the image to your SD card using `sudo dd if=reform-system-imx8mq.img of=/dev/sdx bs=8M status=progress`.
## Advanced: Grow the Root Partition of the Flashed Image
You can extend the size of the second partition to use the full size of your SD card using the following commands (again substitute the correct device name):
```
sudo growpart /dev/sdx 2
sudo e2fsck -f /dev/sdx2
sudo resize2fs /dev/sdx2
```
## How to Build the Images
Building the images requires considerable disk space and CPU resources, it is generally only required if you want to contribute to the development of the system images.
To start the process, use `./mkimage.sh`. To start over, execute `./cleanup.sh` to delete the existing userland and image.
