I am using the USB port of the Raspberry Pi Pico as my debug port when running C programs on the Pico. I have noticed that sometimes when I connect to the Pico USB using Putty in serial port mode, it takes forever (at least 5min) to connect and display the Putty terminal window. I have done the following to eliminate this issue:
- Multiple reboots of the Pico before I am able to connect immediately.
- Removing Pin configuration and initialization code eg: gpio_init(2); gpio_set_dir(2, GPIO_OUT); and so on. I noticed when doing this I connect immediately. Put this code back and I am back to waiting 5min for Putty to connect or resetting the device multiple times. Does anybody know why this is happening?
Many Thanks.
