BOOT Configuration Port
The STM32 chip on the Board Type C has two pins: BOOT0 and BOOT1. The STM32 has three boot
methods and the level status of the two pins when the chip is reset determines the boot method after
the chip is reset. The Board Type C’s BOOT configuration schematic diagram is shown below.

The level of the two BOOT pins is set to low by default. When powered on, STM32 boots from user
flash memory. The reset level status of BOOT0 and BOOT1 can also be configured using jumpers. As
shown below, the BOOT configuration pin is pinned out by using 2 x 2 rows of pin headers spaced 2.54
mm apart. For example, when BOOT0 = 1 and BOOT1 = 0, STM32 boots from the system memory
and enters DFU (Device Firmware Update) mode. Refer to the Micro USB Port section for more
information.
