Boot option

The STM3210C-EVAL board is able to boot from:

●

Embedded user Flash

●

System memory with boot loader for ISP

●

Embedded SRAM for debugging.

The boot option is configured by setting switches SW1 (BOOT1) and SW2 (BOOT0). The

BOOT0 can be configured also via the RS-232 connector CN6.

Description

Configuration

JP25

JP25 selects one of the three possible power supply resources.

For power supply jack (CN18) to the STM3210C-EVAL only, JP25 is set as shown:

(Default)

For power supply from the daughterboard connectors (CN8 and CN9) to the

STM3210C-EVAL only, JP25 is set as shown:

For power supply from USB (CN2) to the STM3210C-EVAL only, JP25 is set as shown:

For power supply from power supply jack (CN18) to both the STM3210CEVAL

and daughterboard connected on CN8 and CN9, JP25 is set as

shown to the right (the daughterboard must not have its own power supply

connected):

JP24

Vbat is connected to 3.3 V power when JP24 is set as shown: (Default)

Vbat is connected to battery when JP24 is set as shown:
