What is a new STM32L053 Discovery board supposed to do?

[DChin.1]

I just received 2 STM32L053 Discovery evaluation boards. Is there a demo preloaded on the board? What is it supposed to do? After I plugged power into USB ST-LINK, the first board cleared the display while the second did not. Then the boards do nothing that I can tell. I was expecting the touch sensor to update the display. The Reset button doesn't do anything either. I have jumpers in CN4 and JP4 is On. At least, when I connect the USB, LD1 blinks a few times. I would like to know if these boards are functional before trying to write some code for it. Thanks.

They should have a demo app, I don't know the history or provenance of the boards you have.

You should plug in via the Top-Center CN1 USB connector, drivers may need to complete installation process.

There are a whole bunch of Applications, Examples and a Demo in the CubeL0 package, you could perhaps build/test those before writing your own code.
