Hi folks,

I have ST's Flash Loader Demo application for programming via a UART and was wondering if anyone knows if there's an equivalent for programming via USB. I want to use the DFU bootloader so I can program without the need for the ST-Link adapter or an IDE - all I would need would be a USB cable, the Flash app and my binary file. Anyone able to help?

Cheers!

Dear all,

I reply to this post because we got some problem with the implementation of DFU dlls on our PC software.

In fact, it seems that sometimes, this dll stops to response to our request. It appears most of the time during the ''erase'' phase.

Is there any guideline or any other document about the integration of this dll on a PC software ?

Moreover, is there any function on the dll to escape correctly from a blocking point ?

Thank you in advance for your help.

Regards,

Thomas

For information, we have no problem when we are using DfuSe to upgrade our firmwares.

That's why I think the problem comes from the dlls.

Anybody have an idea about that problem ?

Thanks
