Can the mbed team edit this page to warn about PA_13 and PA_14 being SWD pins

I assigned these pins as GPIO and couldn't use the ST-LINK interface. Thought I had bricked it but loaded blinky via the online compiler to restore it.

You basically cannot use these pins as GPIO and use the debugger. A warning describing this might be helpful to others if they come across this situation.

I think the pinout diagram should be updated to show this also.

Affordable and flexible platform to ease prototyping using a STM32F411RET6 microcontroller.

I totally agree with your opinion!!
In addition, Nucleo series mbed boards are used same PCB.
This means that this is not only for F411RE but also all of Nucleo issue.
