Flash mcu by pendrive memory

Hi,

I need to do a project where the mcu has to be flashed by an usb pendrive.

Some time ago I think I read that the mcu STM32F1xx family has this feature, but I don't found now.

It's the STM32F1xx correct or anyone knows about other mcu capable of doing that ?

thanks.

They never had.

This was/is a feature of second-stage bootloaders, like mbed.

I don't recall an USB MSC host for the F1's

The F4's had a "fwupgrade" example for the STM32F407-DISCO, which could be back ported to F2 and other F4 boards.

There should also be F7 examples of this also using the HAL libraries.

SD Card might be an easier path, all F1 can use SPI, and several support SDIO
