Can the ST-Link on a STM32F0Discovery be disabled?

On the STM32F0Discovery, there's both an ST-Link chip and the main STM32F051R8T6 MCU.

Is it possible to power up and use the STM32F051R8T6 without also bringing up the ST-Link?

If so, how?

Thanks in advance.

Power the VDD side of the JP2 jumper. Remove the JP2 jumper. Remove the ~~CN1~~ CN2 jumpers.

Based on the schematic, seems like that should work.

Thanks. One question. CN1 is the USB socket. Are you saying that must be desoldered?

Sorry, I meant CN2. The jumpers that connect SWDIO/SWCLK to the ST-Link.
