2.1 Development and debug support
Version 2 of the ST -LINK, called ST-LINK/V2, is embedded on the board. This tool allows on-board program loading and debugging of the STM32L using the JTAG or SWD interface. Third-party debug tools are also supported by the JTAG (CN9) or Trace (CN8) connectors. To communicate with the embedded ST -LINK/V2, a specific driver needs to be installed on your PC. To download and install this driver, refer to the Software and development tools page for the ultra low power STM32L family available on www.st.com (the install shield is called ST -LINK_V2_USBdriver.exe). The embedded ST -LINK/V2 connects to the PC via a standard USB cable from connector CN11. The bicolor LED LD5 (COM) advises on the status of the communication as follows: 1. Slow blinking Red, then Off: At power-on before USB initialization. 2. Fast blinking Red, then Off: After the first correct communication between PC and ST - Link/V2 (enumeration). 3. Red On: When initialization between PC and ST -LINK/V2 is successfully finished. 4. Green On: After successful target communication initialization. 5. Blinking Red/Green: During communication with target. 6. Green On: Communication finished and OK. 7. Orange On: Communication failure. Note: It is possible to power the board via CN11 (embedded ST/LINK/V2 USB connector) even if an external tool is connected to CN8 (trace) or CN9 (external JTAG and SWD).
2.2 Power supply
The STM32L152-EVAL is designed to be powered by a 5 V DC power supply and to be protected by PolyZen from a wrong power plug-in event. It is possible to configure the evaluation board to use any of the following four power supply sources by setting jumpers JP12, JP13 and JP4 (see Table 1).
- 5 V DC power adapter connected to CN12, the power jack on the board (power supply unit (PSU on silk screen)). The external power supply is not provided with the board but can be ordered separately. Note: The AC220V to DC5V power adapter PSU-5V2A (recommended, can be ordered from ST order code PSU-5V2A) or equivalent (polarity compatible with CN12) can be used to power the STM32L152-EVAL board via its power jack CN12.
- 5 V DC power with 500 mA limitation from CN11, the USB type B connector of ST - LINK/V2 (USB 5 V power source (ST-LINK/V2 on silkscreen)).
- 5 V DC power with 500 mA limitation from CN1, the USB type B connector (5 V power source (USB on silkscreen)).
- 5 V DC power from CN6, the extension connector for daughterboard (daughterboard power source (Daughter board on JP12 silkscreen). Various LEDs indicate the power status:
- Red LED LD9 is lit when the STM32L152-EVAL board is powered correctly by 5 V.
- Red LED LD8 is lit when MCU is powered by low voltage (VDD < 1.8 V).
- Y ellow LED LD7 is lit when MCU is powered by voltage (1.8 V<VDD<2.2 V).
- Green LED LD6 is lit when MCU is powered by voltage (2.2 V<VDD).
