Printf via SWV doesn't print anything
I have added the syscalls.c(into the source location, where main.c is)...My source configuration is 72MHz (system clock), I have included CMSIS workspace in my directory... Changed the write routine... Still doesn’t work... Code compiles, but doesn’t work...
I am running a GPIO example, not RTOS. Will this method mentioned by you still work?
In addition, I have couple more question. how adding syscalls.c and changing the _write() function changes the implementaion of printf? how the syscall.c changes the implementation in ?
I really need get printf or ITMSend recieve working as ap. I am using stm32f3 Discovery. How to determine the clock frequency and port number so that we can see in STLInk? Please advice.
Thanks in advance
