Debugging: printf() problem

I often experience that the printf() output gets malformed. Each call results into characters in the console, but they are all unreadable chinese characters. Most of the times the first few lines appear OK, and from then on only garbage.

I expected this had something to do with the clock settings, but even using the default (48 Mhz) clock, I have this problem.

What could be causing this behaviour?

Semihosting printf to console is very slow ;)

The problem is not that its slow (its fast enough for me), but that I get a chinese character when i call print("1");

Could be useful if you disclose us which OS / LPCXpresso / MCU / printf-Setup you are using :confused:

Also a sample project could help to verify this effect :)

Currently I experience it with LpcExpresso v5 and a LPC11U35, but I noticed the same problem with LpxPresso v4 and a LPC1768 too in the past. Few days ago I had with a LPC11U14.

So the LpcExpresso version / MCU model seemed not to matter to me ;)

As zero said, can you provide a project that shows the problem?
