Flashing

1. Clone this repo and move into the directory.

   git clone https://github.com/gkits/gosnooze
   cd gosnooze

2. Start the Pico W in boot selection mode by holding down the BOOTSEL button while connecting it to your computer via USB.

3. Mount the Pico W to your filesystem.

   1. Find the correct block device by running lsblk. The correct device should look like something like this:

      sdx           x:xx   1  128M  0 disk
      └─sdx1        x:xx   1  128M  0 part
      

   2. Mount the device to your filesystem:

      mkdir /mnt/RPI-RP2
      mount /dev/sdx1 /mnt/RPI-RP2

4. Flash the device:

   tinygo flash -target=pico-w

The device should now reboot and after some time the display should show the time.
