Hello all,

I am trying to get started with a STM32DISCO board, like described here:

https://www.st.com/en/evaluation-tools/32l476gdiscovery.html#documentation

However, I can't get it powered.

I use the USB USER connector to power it with my laptop.

SB settings 13, 15, 16 and 17 are correct.

I also can't find demo code for this board.

STM32L4 series

Powering the 32L476GDISCOVERY via external 5V_I or USB USER CN7 (USB FS connector) is mentioned in UM1879, section 10.2, page 16:

To use the USB USER CN7 to power supply the board, a jumper needs to be placed between VUSB pin 4 and the pin 3 5V_I of P2 header (see Figure 8).

The binary of the demo code is available at the website of the 32L476GDISCOVERY.

Does it answer your question?
