Hello,

I have a evaluation board STM32L552E-EVAL, and I would like to know what is this part used for ?

I see 2 pins (USB_D_N and USB_D_P) that connect to the STM32F103CBT6

What is it for ? To program the component and debug. Thank you for your answer

Regards

That is the ST-Link - for programming and debugging

What part - the USBLC6-2 ?

Its datasheet tells you what it's for:

>>To program the component and debug. 

I'd have thought this would have been readily obvious, the on-board debugger. ST-LINK/V2-1

Provides the USB CDC connectivity to a L552 UART, and an USB MSC to drag-n-drop firmware binaries, as originally used by mbed

Hi,

Thank you, in fact I would like to program and debug via J-LINK SEGGER. In fact, on my real card I do not use the ST-LINK (for consumption). Do you know where I can find the information to configure the J-LINK to be able to work under STMCubeIDE ? I can see some information but it's not very clear for my. 

Thank you

I'd imagine under debugger settings, perhaps videos on YouTube if reading not strong

See this if you want it to present as a "J-Link OB"
