That is exactly the same behaviour I got on the F330. My code is a mess but it triggers exactly in the same way. > > I've tried different memeory models and reentrency, but don't see a > change in behaviour. printf() takes us over 4K of flash, but the > C8051F330 has 8KB, so we should be ok. > > Philipp I used my own function to send strings and tried all kinds of tricks but couldn't get around this issue. The Keil compiler that you get with the Silabs Simplicity Studio works without any problems for me. Maybe it would be worth porting your small example to Keil and see the difference in assembly ?
