You will need to build the image manually. But don't worry, it's [very simple](building_os.md).

## Flashing the image
|
|
|
|
|
|
|
|
|
|
!!! tip
|
|
|
|
|
After inserting the memory card into your computer, ignore request to format. This is not nessessary.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### Using Linux CLI
|
|
|
|
|
|
|
|
|
|
Decompress (if nessessary) and flash the image. **Be careful when choosing the device path, it may be different on your machine**:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
[user@localhost]$ xz --decompress v2-hdmi-rpi4-latest.img.xz
|
|
|
|
|
[user@localhost]$ sudo dd if=v2-hdmi-rpi4-latest.img of=/dev/mmcblkX
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
You can also use `dd_rescue` or `ddrescue`.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### Using RPi Imager (Linux, MacOS and Windows)
|
|
|
|
|
|
|
|
|
|
1. Download and install **the latest version** of [RPi Imager](https://github.com/raspberrypi/rpi-imager/releases).
|
|
|
|
|
|
|
|
|
|
2. Run RPi Imager:
|
|
|
|
|
|
|
|
|
|
<img src="imager-1.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
3. Press **CHOOSE OS** and select **Use custom** image at bottom of the list:
|
|
|
|
|
|
|
|
|
|
<img src="imager-2.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
4. After clicking on this item, select the image file (`*.img` or `*.img.xz`), then click **CHOOSE STORAGE**:
|
|
|
|
|
|
|
|
|
|
!!! warning
|
|
|
|
|
Check the advanced settings (`CTRL+SHIFT+X`), make sure they are blank or the flash will fail.
|
|
|
|
|
|
|
|
|
|
<img src="imager-3.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
5. Insert the memory card into the card reader. Choose the card reader from this list. **Be careful** and choose the right device:
|
|
|
|
|
|
|
|
|
|
<img src="imager-4.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
6. After choosing the memory card, press the **WRITE** button. Confirm the operation when you are asked about it:
|
|
|
|
|
|
|
|
|
|
<img src="imager-5.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
7. Wait for the process to finish. Get yourself a coffee or do some stretching :)
|
|
|
|
|
The process may hang at 99% for a long time, this is okay, just wait for it to complete.
|
|
|
|
|
|
|
|
|
|
<img src="imager-6.jpg" width="400" />
|
|
|
|
|
|
|
|
|
|
8. Remove the memory card after successful completion. If an error occurs during flashing or booting PiKVM, repeat the process.
|
|
|
|
|
If the error persists, use a different card.
