Hi,

Actually we require to do bootloader development for self program without any external host like ST-Link or debuggers in STM32F205xx controller, we should program from USB mass storage device.

Our requirement is once we connected pen drive, have to check and read .HEX file if available, after reading it should be update self program according bootloader code. Is this possible to implement for F205 controller..

Kindly help on this regard.

Thank you.

Should be a workable example for the STM32F407 DISCO​ board. FW Upgrade as I recall. Other IAP examples are also available. Yes the F4 USB code should be compatible with the F2.
