STM32F4DISCOVERY 4.2 Hardware and layout Embedded ST-LINK/V2 The ST-LINK/V2 programming and debugging tool is integrated on the STM32F4DISCOVERY. The embedded ST-LINK/V2 can be used in 2 different ways according to the jumper states (see Table 2): ● Program/debug the MCU on board, ● Program/debug an MCU in an external application board using a cable connected to SWD connector CN2. The embedded ST-LINK/V2 supports only SWD for STM32 devices.
PAGE 14
Hardware and layout 4.2.1 STM32F4DISCOVERY Using ST-LINK/V2 to program/debug the STM32F4 on board To program the STM32F4 on board, simply plug in the two jumpers on CN3, as shown in Figure 8 in red, but do not use the CN2 connector as that could disturb communication with the STM32F407VGT6 of the STM32F4DISCOVERY. Figure 8.

STM32F4DISCOVERY 4.2.2 Hardware and layout Using ST-LINK/V2 to program/debug an external STM32 application It is very easy to use the ST-LINK/V2 to program the STM32 on an external application. Simply remove the 2 jumpers from CN3 as shown in Figure 9, and connect your application to the CN2 debug connector according to Table 3. Note: SB11 must be OFF if you use CN2 pin 5 in your external application. Table 3. Figure 9.
PAGE 16
Hardware and layout 4.3 STM32F4DISCOVERY Power supply and power selection The power supply is provided either by the host PC through the USB cable, or by an external 5V power supply. The D1 and D2 diodes protect the 5V and 3V pins from external power supplies: 4.4 4.5 16/38 ● 5V and 3V can be used as output power supplies when another application board is connected to pins P1 and P2. In this case, the 5V and 3V pins deliver a 5V or 3V power supply and power consumption must be lower than 100 mA.
PAGE 17
STM32F4DISCOVERY 4.6 Hardware and layout On board audio capability The STM32F4 uses an audio DAC (CS43L22) to output sounds through the audio mini jack connector. The STM32F4 controls the audio DAC through the I2C interface and processes digital signals through I2S connection or analog input signal. ● ● 4.7 The sound can come independently from different inputs: – ST MEMS microphone (MP45DT02): digital using PDM protocol or analog when using the low pass filter.

Hardware and layout STM32F4DISCOVERY 4.10 OSC clock 4.10.1 OSC clock supply If PH0 and PH1 are only used as GPIOs instead of as a clock, then SB13 and SB14 are closed and R24, R25 and R68 are removed. ● ● ● 4.10.2 MCO from ST-LINK. From MCO of the STM32F103. This frequency cannot be changed, it is fixed at 8 MHz and connected to PH0-OSC_IN of the STM32F407VGT6. Configuration needed: – SB13, SB14 OPEN – R25(a) removed – R68(a) soldered Oscillator onboard. From X2 crystal.

STM32F4DISCOVERY Hardware and layout 4.11 Solder bridges Table 4. Solder bridges State(1) Bridge Description OFF X2, C14, C15, R24 and R25 provide a clock. PH0, PH1 are disconnected from P2. ON PH0, PH1 are connected to P2 (R24, R25 and R68 must not be fitted). SB3,5,7,9 (Default) ON Reserved, do not modify. SB2,4,6,8 (Reserved) OFF Reserved, do not modify. SB15,16 (X3 crystal) OFF X3, C16, C27, R21 and R22 deliver a 32 KHz clock. PC14, PC15 are not connected to P2.
