I notice that the connectivity line supports USB upgrades through DfuSe via it's boot-loader in the system memory. The STM32F103, which I'm using, only supports USART1 for use of the boot-loader in system memory.

1.) Does this imply that I have to make my own app, IAP, to support upgrades via the USB on a 103 device?

2.) Is there source code for this within ST?

3.) Will it work with DfuSe or do I have to make a vendor unique command?

Thanks in advance

Hi Jeff,

I'm working on a project using the STM32F103 microcontrollar and I need your help:

I started with an appliction note from ST site but I need to install the DfuSeDemo in my PC to program the Demo and I searched for the .exe and didn't found it.

Can you tell me where I find it..

Best Regards,

Mariem

Hi jeff,

Actually, if you want to build your own USB bootloader on STM32F103 it is theorically possible:

- You take the DFU demo provided by ST (

http://www.st.com/stonline/products/support/micro/files/um0424.zip

)

- You modify it a little accordingly to the system boot application note (

http://www.st.com/stonline/products/literature/an/14156.pdf

) (--> add erase, option bytes management, device ID, bootloader version ...)

If you do so, it should work properly on DFUse just like the STM32F105/7 bootloader.

There will be some more details if you decide to go through this way.

But it doesn't seem too hard to do.

Hope good luck for you :)

Cheers.
