Boot Option - ST STM3220F-EVAL User Manual

For power supply from power supply jack(CN18) to both STM3220F-
EVAL and daughter board connected on CN1 and CN3, JP18 is set as
shown to the right (daughter board must not have its own power
supply connected)
Vbat is connected to battery when JP19 is set as shown to the right:
Vbat is connected to 3.3V power when JP19 is set as shown to the right:
JP19
(Default setting)
To enable MCU power consumption measurement, JP16 should be re-configured as
described in table 2.
Table 2 MCU Power consumption measurement related Jumpers
JP16 is useded to bypass MCU power consumption measurement circuit,
it's set to close by default.
JP16 JP16 need to be re-configured to open for MCU power consumption
measurement.
Default setting: Fitted
The LED LD9 is lit when the STM3220F-EVAL evaluation board is powered by the 5V
correctly.

1.2 Boot Option

The STM3220F-EVAL evaluation 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 switch SW1 (BOOT1) and SW2 (BOOT0). The
BOOT0 can be configured also via RS232 connector CN16.

set as shown to the right. BOOT1 is don't care in this
configuration.
(Default setting)
BOOT0 & 1 STM3220F-EVAL boot from Embedded SRAM when
BOOT0 and BOOT1 are set as shown to the right.
