Hello, I am working on making an application run on the W5500-EVB RP2040 boards on its own instead of via NSH. I've noticed that the moment I turn off the USB console option (i.e. I don't use boardctl to start the USB driver and duplicate the file descriptor as 0, 1 and 2), the application no longer functions (it should connect to something over the network and it doesn't). I'm suspicious that it is hanging on printf statements because it no longer has a stdout to write to?
Any suggestions to just have fprintf and printf statements ignored so that the application can run normally just without console output? Alternatively I wouldn't mind keeping the USB device driver as an option, but I've noticed that if it is not plugged into a receiving computer the program hangs as well. It seems like it requires some receiving device in order to continue outputting. Is there a way I can make it non-blocking? Thank you for your help, -- Matteo Golin
