Hi,
P201 10-pin connector on ST253911B-DISCO is a JTAG/SWD interface to assist in software development on the onboard STM32L476RE. It can be connected to an external ST-LINK/V2 device using a 9-pin Cortex®-M adapter. See User Manual UM2042 for description of the ST253911B-DISCO and see STM32L476RE Reference manual RM0351 for details about the Single Wire/JTAG Debug Port.
