Introduction to MINI-M4 for STM32 Miniature and powerful development tool designed to work as stand alone device or as MCU card in DIP40 socket. MINI-M4 for STM32 is pre programmed with USB HID bootloader so it is not necessary to have external programmer. If there is need for external programmers (mikroProg™ or ST-LINK V2) attach it to MINI-M4 for STM32 via pads marked with PA14 (TCK/SWC), PA13 (TMS/SWD), PA15 (TDI), PB3 (TDO) and RST#.

1. Programming with mikroBootloader step 1 – Connecting MINI-M4 You can program the microcontroller with bootloader which is pre programmed into the device by default. To transfer .hex file from a PC to MCU you need bootloader software (mikroBootloader USB HID) which can be downloaded from: http://www.mikroe.com/downloads/get/1938/ mini_m4_stm32_bootloader_v200.zip 01 After software is downloaded unzip it to desired location and start mikroBootloader USB HID software.
step 2 – Browsing for .HEX file step 3 – Selecting .HEX file 01 01 02 Figure 1-2: Browse for HEX Figure 1-3: Selecting HEX 01 Click the ”Browse for HEX” button and from a pop-up window (Figure 1-3) choose the .HEX file which will be uploaded to MCU memory. 01 Select .HEX file using open dialog window. 02 Click the ”Open” button.
step 4 – Uploading .HEX file 01 01 Figure 1-4: Begin uploading Figure 1-5: Progress bar 01 To start .HEX file bootloading click the ”Begin uploading” button. 01 You can monitor .
step 5 – Finish upload 01 Figure 1-6: Restarting MCU Figure 1-7: mikroBootloader ready for next job 01 Click the ”OK” button after uploading is finished and wait for 5 seconds. Board will automatically reset and your new program will execute.
