Download FW via USB

[Treacy Yao]

I want to use STM32F103C8 module, and upgrade FW with USB. We do upgrade with UART before. So my question is:

1.Can this module upgrade FW with USB?

2.Which tool I can use to dowanlod the .bin file via USB? Still the STMFlashLoader Demo tool?DFUSeDemo tool?

3.Any related document for this function(I especially want to know the document that the first factory out device downloading(no any software embedded in), how to enter ram? or other useful steps)?

App Note AN2606 should list available functionality.

Use the STM32 Cube Programmer, in USB mode, to send .DFU files.

I believe there is another document describing the .DFU format

From the Note, STM32F10xxx devices bootloader just have "USART1 bootloader", but "STM32F105xx/107xx devices bootloader" have "USART1 bootloader and DFU bootloader". I use STM32F103C8 module, is there any problem use DFU function?
