3.8 Program the Embedded Pi
3.8.1 ISP mode
In ISP mode, a PC programs the MCU onboard via the serial port (JP7-TX1 and JP7-RX1), refer to
section
3.6.1 . To use this mode, you need to set BOOT0 to 1 (high level), and BOOT1 to 0 (low
level) – which has been done on hardware. In this case, you only need to press the BOOT0 button
to enter this mode when Embedded Pi is powered on.
The next steps are as below:
1) Install the ISP tool for Embedded Pi on your PC or Raspberry Pi. There are many ISP tools for
PC, and ST has provided a version for Windows system only. For details, please refer to
http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_
MANUAL/CD00171488.pdf
. Raspberry Pi uses the Linux system, where no ISP tools are
available yet, and need to be developed.
2) Disconnect Embedded Pi from power.
