2.2 Boot
option
The STM3210E-EVAL evaluation board can boot from:
●
Embedded user Flash
●
System memory with boot loader for ISP
●
Embedded SRAM for debugging
The boot option is configured by setting the switches BOOT0 and BOOT1.
2.3 Clock
source
Two clock sources are available on the STM3210E-EVAL evaluation board for STM32F103
and RTC.
●
X2, 32KHz crystal for embedded RTC.
●
X1, 8MHz crystal with socket for STM32F103ZGT6 microcontroller, it can be removed
from socket when internal RC clock is used.
2.4 Reset
source
The reset signal of the STM3210E-EVAL evaluation board is low active and the reset
sources include:
●
Reset button B1
●
Debugging tools from JTAG connector CN7 and trace connector CN9
●
Daughterboard from CN11
