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.
