Printf via SWV doesn't print anything

Hello All,

Using ITM is pretty simple.

My usage:
in syscalls.c, add #include “stm32f4xx.h” (depends on your device) & (you should include CMSIS folder)
and modify the _write function :

int _write(int file, char *ptr, int len)
{
	int DataIdx;

	for (DataIdx = 0; DataIdx < len; DataIdx++)
	{
	   ITM_SendChar( *ptr++ );
	}

	return len;
}


After that, you can use printf to output message via printf.

To visualize the ITM output, you can use ST-Link Utility (menu : ST-LINK > Printf via SWO Viewer)
