Tutorial – Jump to system memory from software on STM32 1

Tutorial – Jump to system memory from software on STM32

One of you are already familiar with STM32 feature of embedded bootloader for software download to flash. This memory is called system memory and is normally accessible with BOOT configuration (either pin hardware or option bytes (later OB) in flash software). Normally, if you want to jump to system memory, you have to setup pin/OB and reset device. If you have OB setup, this is ok, but since you need at least one BOOT pin in hardware, this can lead to hardware...

Program STM32F4 with UART 10

Program STM32F4 with UART

STM32F4 devices have great feature. They can be programed with only USB to UART converter. Each device has bootloader inside, which supports UART programming. This is not very great method for Discovery boards, because they have better and faster solution on board, ST-link. But if you are working own board, then this solution can be quite nice. In this tutorial, I will go through step-by-step how to program device with USB->UART converter. I will use FTDI’s home made converter. This...
