Setting Up Raspberry Pi SD Card Flasher

This README provides guidance on configuring your config.yaml file with the correct SD card device path, and retrieving your current network SSID and Wi-Fi password.

Finding the Correct SD Card Device Path

To identify the correct device path for your SD card to use in your config.yaml, you can follow these steps:

Insert your SD card into your computer.
Open a terminal.
Run the command lsblk before and after inserting your SD card. Note any new device that appears in the list; this is likely your SD card.
Identify your SD card based on its size and the fact it typically won't have any mount points if it's freshly inserted or not automatically mounted.

For example, from your output, if sdb appears after inserting an SD card, and assuming no partitions are listed under it (or it's a new device showing up in the list), sdb is likely your SD card.

Example Entry for config.yaml:

sd_card: "/dev/sdb"

Important: Make sure to replace /dev/sdb with the actual device path from your lsblk output. Using the wrong device path can lead to data loss if directed at the wrong storage device.

Finding Your Current Network SSID and Wi-Fi Password

Finding SSID

To find out which Wi-Fi network your machine is currently connected to, you can use the following command in the terminal:

nmcli -t -f active,ssid dev wifi | egrep '^yes' | cut -d':' -f2

This command lists active network connections and extracts the SSID of the currently active Wi-Fi network.

Finding Wi-Fi Password

To retrieve the password for the Wi-Fi network you're currently connected to, you can use the following command:

for file in /etc/NetworkManager/system-connections/*; do
    echo "Checking $file for Wi-Fi password:"
    sudo grep psk= "$file" | cut -d'=' -f2
done

This command accesses the network configuration files managed by NetworkManager and extracts the password. Note that you may need superuser privileges to view these files.

Note: These commands assume you are using NetworkManager, which is common in many Linux distributions. If your distribution does not use NetworkManager, you'll need to locate your Wi-Fi configuration details in the specific configuration files or tools your system uses.

Updating config.yaml

Once you have the SD card path, SSID, and Wi-Fi password, update your config.yaml accordingly:

sd_card: "/dev/sdb"
image_url: "https://downloads.raspberrypi.com/raspios_armhf/images/raspios_armhf-2024-03-15/2024-03-15-raspios-bookworm-armhf.img.xz"
image_path: "./2024-03-15-raspios-bookworm-armhf.img.xz"
ssid: "Your Wifi User Name"
wifi_password: "Your Wifi Password"
expected_checksum: "52a807d37a894dfcb09274382762f8274c7044ce3d98040aba474e0af93b85ab"

Replace each placeholder with the actual data from your environment.

Manual dependency installation

wget https://raw.githubusercontent.com/chGoodchild/raspiFlasher/master/manual_setup.sh
chmod +x manual_setup.sh
./manual_setup.sh

OpenWRT

Only works if raspbian is flashed just before flashing OpenWRT.

Have to figure out why this is the case...
