Hi, can you help me with a new problem I am having using the serial USB debugging facility.
I have two mbeds, one soldered into a pcb with interface chips etc., the other just a naked module.
I have used the serial debug for many months without issue so are happy that I understand the setup. Today my soldered in mbed nolonger generates any serial debug output, Windows XP does not see the port (usually 10).
The standalone mbed does generate debug output and Windows sees the mbed on port 10.
The soldered in mbed runs different code, but the debug bits look the same as the standalone module. I can't run the same code in the standalone module as it needs the support chips to function.
I shall try downloading some temporary simplified diagnostics code to both modules to see what happens, but as the coding requirements are so simple for serial debug, what can I be doing wrong?
What actually makes Windows see the com port?
All other aspects of my code are working fine which includes ADCs, DAC's, LCD, RTC, USB file reading and writing, timing etc., and the serial debug had worked on earlier code development versions on the soldered in module.
Currently Flash is at 6% and RAM at 79% used.
