Boot option
The STM32100B-EVAL board can boot from:
The boot option is configured by switches SW1 and SW2 as shown in
The hardware implementation of JP4 and the RS-232 interface can be only used when the
Boot0 is at a high level through the onboard switch SW2, which is not the most common
case of usage.

STM32100B-EVAL boots from user Flash when SW2 is set as
shown to the right (default setting).
In this configuration, the position of SW1 does not affect the boot
process.
STM32100B-EVAL boots from embedded SRAM when SW1 and
SW2 are set as shown to the right.
STM32100B-EVAL boots from system memory when SW1 and
SW2 are set as shown to the right.
BOOT0 pin of the STM32F100VBT6 is connected to the RS-232
connector CN10 pin 8 (CTS) for ISP support when JP4 is closed.
This configuration is used for boot loader application only.
Default setting: not fitted.
VDD power is directly connected to MCU VDD when JP8 is set as shown:
(Default setting)
Note: For manual IDD measurement JP8 must be removed and replaced by an ammeter
connected between JP8 pins 1 and 2.
Connect VDD power to MCU with current-sampling resistor, 1
for IDD current measurement when JP8 is set as shown:
(Available only on PCB rev B.) Connect IDD_CNT_EN (PE14) to Anti-tamper (PC13) for
IDD current measurement in standby mode when JP12 is closed.
Default setting: Not fitted
