ARM example It is a good idea to download the latest time limited evaluation version Page 11 of 31 OLIMEXO 2015 STM32 H405 user s manual 3 3 Powering the board The board can be powered in one of the following ways 1 Using the JTAG or SWD debugger the board gets powered via the 20 pin 0 1 step JTAG connector note that some tool might hold the board in RESET state make sure to release the microcontroller from RESET to be able to see the execution of your code 2 Using USB cable the board gets powered via the USB connector the power is provided typically by your computer s USB port 3 Using external power supply in this case the board gets powered via the EXT2 header provide 5 DC to pin 26 of this header then connect the power supply s GND to pin 25 of EXT2 3 4 Programming the board The programming of the board is also fairly straight forward unlike the software development for the board 3 4 1 Using JTAG debugger This is the recommended method of changing the software of the board This is fairly simple from hardware point of view just plug the male 20 pin JTAG connector of your hardware tool to the 20 pin female JTAG connector of STM32 H405 Refer to the documentation of your debugger and also to the documentation of the software of choice on instructions how to set the environment 3 4 2 Using USB cable The board can be programmed without a debugger tool In this case you only need
5. The board must not be exposed to high electrostatic potentials A grounding strap or similar protective device should be worn when handling the board to avoid electrostatic discharge 3 2 Requirements In order to set up the STM32 H405 optimally you would need a hardware debugger tool and compatible software tools More detailed information may be found in the sub chapters below 3 2 1 Hardware requirements Standard ARM JTAG SWD debugger programmer it can power the board and gives you the ability to program debug the board to select the correct tool make sure that it is compatible with the software tools which you are going to use during development Also makes sure that the tool is compatible with the STM32F405 processor IMPORTANT The board can be programmed using only a USB cable However it is a slow process this way of programming is not suitable for evaluation research and development Using the USB DFU bootloader might be good idea only if you need to program the board once or twice Additional components can be acquired in order to increase the functionality of the board USB cable with type A and type B connectors in case you want to power the board from the USB port of your personal conputer or alternatively if you want need to utilize the board s USB interface Jumper wires allow solderless access to the exposed pins if you want to directly connect to the extension headers use wires with a female conne
