I have a problem with printf

Does it only stop working when you try to print?

If you have the following combination, the printf() will become a blocking operation when the output buffer fills, and has nowhere to go..:

1. jtag_uart (defined as STDOUT)

2. _NO_ system timer (interval timer, defined as the system clock in the IDE)

3. _NO_ cable connected via the jtag_uart (or no program running on the other end of the cable)

Either add a system timer to your system or, if your printf()s are for debug,# ifdef them out for "release" builds.

That is, of course, if this is what you have done. :-)

Best Regards and Best of Luck!
