6/20/2023 0 Comments Nucleo f401re i2c portsDownload latest DFU image with Firmware for NUCLEO_F401RE board. Download newest stable verion of firmware from official website here is a link. Now we can upload new Firmware with Micropython into our tagert microcontroler STM32F401RE. After a few moments, we will receive information about the success of the operation. Be sure is your Board is connected to computer via USB interface. In new window ST-LINK Upgrade click on button Device Connect and Yes. Run application and choose ST-LINK -> Firmware Update. Now you can plug-in USB cable in your Computer.īefore upload Firmware with Micropython you can update ST-Link Firmware on Nucleo board but this step is not obligated.ĭownload and install on your computerr STM32 ST-LINK Utility software. For this purpose, connect the connectors on CN2 header. Move resistor 0R into SB63 and SB62 on bottom side of our Nucleo-F401RE board.īe sure is your ST-Link is connecte with our target microcontroller STM32F401RE. Reconnect Solder Bridge number SB14 and SB13. Solder Bridge number SB63 and SB62 are respectively TX and RX pins. We must use Solder Bridge on bottom side of the board. However default UART2 on NUCLEO-F401RE is disabled. Dor communication with main microcontroller we use UART2 avilable on pins PA2 (TX) and PA3 (RX). We use build-on-platform ST-Link programmer to flash our STM32F401RE. We need NUCLEO-F401RE base board with microcontroller STM32F401RE to achieve this goal. This article describe how to launch Python code on STM32 Cortex-M microcontroller.
