Startup File for Network

If your firmware is configured to have a file storage on the flash memory of the Pico board just like pico-jxgLABO does, you can create a .startup file in the root directory of the primary drive (e.g., L:) to automatically execute commands at startup. This is useful for configuring the network settings without needing to manually enter commands each time.

Here’s an example to establish Wi-Fi connection and start a Telnet server at startup:

.startup
1
2
3
net wifi-connect {ssid:'SSID' password:'PASSWORD'} config {addr:XXX.XXX.XXX.XXX}
telnet-server start
led on flip:50,500,50,500,50,2000

Edit the file above, change SSID, PASSWORD, and XXX.XXX.XXX.XXX as needed, and copy it to the drive.

After rebooting, if all commands in the script run without error, the led command will blink the built-in LED to indicate successful startup. You can set different blink patterns for each board’s IP address for easy identification (e.g., one blink for 192.168.0.101, two for 192.168.0.102, etc.).
