I am trying to get into MQX 3.7 for k40 using a k40 tower dev system with IAR. I compiled and ran the LWGPIO example.
The LED switches off as intended, but the button press is not detected - neither when interrupt driven, nor when polled.
On the other hand when I ran the bare-metal gpio project it works ok, so hardwar eis not the issue.
I also could not see the uart output as it is sent to ttya which is the osjtag and that is in use for debugging. I tried to
change the config to default to ttyd and recompile everything (as per the starters guide), but I did not get output from the serial port either.
Any Ideas ? Has anyone else had these issues?
I am womdering what the learning curve for MQX is going to be like ...
