No STM32CubeMX gerar o projecto no formato Makefile.


Usar o GNU ARM Embedded Toolchain.


É preciso usar um programador ST-Link V2 e o software stlink.

st-flash write build/blinky.bin 0x8000000


Correr o st-util num terminal separado. E depois corre-se o gdb com:

arm-none-eabi-gdb --eval-command="tar extended-remote :4242" build/blinky.elf

More Info

Board marked "STM32F4XX STM32_F4VE V2.0 1509" on the back.

Brief summary of the features

  • Two GPIO headers each with a double row of pins (2 x 30). 54 + 56 = 110 GPIOs in all.
  • Header pins for 5V, 3.3V & GND.
  • A specialised 16 x 2 header marked "TFT" (16 data pins + strobes, and SPI).
  • A 2 x 10 JTAG IDE header.
  • An 8 pin female header for NRF24L01 RF (not WiFi) module.
  • A 4 x 1 header for Serial (Serial 1?).
  • Links for BOOT0 and BOOT1 (PB2)
  • Mini SD slot.
  • Mini USB which provides USB Serial (VCP) via the ST VCP driver (Read ALL the instructions when installing the driver - it's a 2-step process.)
  • 4 buttons (RST, K..UP, K0, K1)
  • KEY1 PE0 (TBC?)
  • LEDs: "D3" = PA5 & "D2" = PA6
  • Power LED = "D1"
  • force re-enum is PD6 (TBC?)
  • RTC and 8MHz crystals.
  • RTC backup battery (CR 1220)

Many boards are fitted with additional flash - often a Winbond W25Q16 chip (16M-bit, 4KB erasable sectors & 32KB/64KB erasable blocks). Flash memory is on SPI1 - CS permanently enabled.

Some boards may have SDRAM pads on the underside, as per the ZET6 variant.

Board schematic: Media:STM32F407ZET6_sch-1.pdf (This is the ZET6 board - all appears correct, other than:

  • Pin numbers on MCU will be different
  • Extend I/O connectors are different (less pins)
  • SDRAM is not implemented on my board)
