Serial?

I've tried the F030R8 Nucleo_printf program, and it doesn't seem to work on any of my Nucleo F030R8 boards (I've tried 3 of them). The LED is flashing at the slower rate, so the program did download correctly, but I'm not seeing any output on com22 with TeraTerm @ 9600-n-8-1-noflowcontrol.

Did I miss a step somewhere?

SB62 and SB63 links worked for me too. Now we are talking :) Thanks Daniel

Had the same problem and it turned out that the solder bridges sb62 and sb63 needed to be soldered (the pins marked as PA_2 and PA_3 were not connected to the mcu!!)

Hi Thor, it should work. If it doesn't, make sure you have a recent version of the ST-LINK/V2-1 USB driver (if you are using TeraTerm I guess you are on Windows) and then update the ST-LINK/V2-1 firmware using the latest version of the STM32 ST-LINK utility. The procedure is described in the 'Nucleo ST-LINK/V2 driver installation and firmware upgrade' section in the page for your board: https://developer.mbed.org/platforms/ST-Nucleo-F030R8/

In case you still have issues, also check that you are using the latest version of mbed.

Hope that helps, Antonio
