Re: STM32L151ZD Bootloader Options - STMicroelectronics Community

I'm having difficulty finding a definite answer to my question in the forums or the application notes.

We were hoping to use the USB to allow us to download our target firmware to our product, thus not requiring our users to be supplied with specialist JTAG cables.

We see the device ''STM32 Bootloader'' when the USB is connected to our PC, however the Flash Loader Demonstrator only supports USART ports.

Is it possible to update the firmware held in the User Flash memory of the device over the USB port, and is there already some PC software (shareware or commercial) to do this?

You definitely want to be focusing on the DFU stuff, not the Flash Loader Demonstrator.
