Hi,

I am using stm32f429 mcu and i can use usb communication with my board. I want to learn how to download my hex file to mcu from usb port of the mcu. In other words i want to use a simple gui software on my computer, i will browse my hex file and i will send all flash data to stm32f429 through usb port. I have investigated the DFU mode, but it requires to use BOOT0/1 pins of mcu and i don't want to use BOOT pins of the mcu. For this, which steps must i follow? Any advise?

I use this for F205 and F405 parts, gets them in DFU mode via USB, update them from there

 

For IAP stuff I use X-MODEM-1K on my USART, it's damn near bullet-proof

Hi,

When i have installed the usb dfu project to my mcu, i can see it as dfu device in device manager, but it say that it can not be started. according to user manual , for dfuse bootloader PA11/12 usb pins of mcu must be used, but i am using PB14/15 pins for usb hs communication with internal fs phy.

Do i need any extra things or anything else ?
