stm32f746 application update using usb dfu bootloader

jschoi · ‎2024-08-28

I am using the STM32F746 Nucleo board.

If you look at the example file, there is a binary (application fw) in the dfu-standard project file
I want to make my own application FW, but when I use the DfuSeDemo program to update the fw, it doesn't work. But the binary ("STM32746G-DISCOVERY_SysTick_0x08008000.dfu") in the provided example file works.

If you look at what I modified on the application side, what did I miss?

There are three points that I modified.
As shown below.

Hello,

Why are you uning DfuSe instead of STM32CubeProgrammer? DfuSe is an old and deprecated tool.

Hello,

The DfuSe program connects to the board, but the STM32CubeProgrammer does not connect.
