Which Raspberry Pi models are recommended for Crowpi2 software?

Crowpi2 software is recommended to run on a Raspberry Pi 4 Model B with 2GB RAM or higher (preferably with 4GB or 8GB).

Why can't the GPIO-0 (SDA0) pin be used?

GPIO-0 (SDA0) is reserved to detect Raspberry Pi startup status in order to control the power on/off on the PCBA board, so without this pin signal being driven 'low', the CrowPi2 will shutdown unexpectedly.

To install the new Raspberry Pi OS, what additional configuration should be made?

After flashing a new Raspberry Pi OS image, you will need to edit the config.txt, located in the /boot directory of the SD card, adding (Cut & Paste) the following statements to the end of the file.

hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=82
hdmi_drive=2
enable_uart=1
gpio=0=op,dl

In addition, after booting up with the new image, open a new Terminal and execute the following commands
git clone https://github.com/elecrow-engle/elecrow_crowpi2.git
cd elecrow_crowpi2/GPIO
chmod +x start.sh
sudo ./start.sh
