Resolved! Hi, I'm using stm32L073Rz , need to know how to configure it as a usb memory device, no demo examples are available for usb memory stick for this chip , i used cubemx to generate code for usb memory class and ran it.

It does not work , it gets detected as unknown device,what am i missing , should i add something more to cube mx generated code. Thanks.

Resolved! STM32L475RG - Having trouble jumping between multiple .bin programs in flash, program stops working.

CURRENT PRODUCT Our existing devices have a custom USB DFU bootloader starting at address 0x08000000. Our main application starts at 0x08008000, after 32Kb of space. I can jump from the main app to the bootloader with no issues (using a NVIC_Systemre...

Hi, We are looking for an IoT Gateway based on STM32 MCU's, the primary reason for going with MCU's is the Low Power consumption feature of these devices, can any suggest me the suitable board/dev kit for our purpose.

As STM32F4 series can run an RTOS,RTOS like FREE RTOS is optimal to use to run multiple threads for our need, can this combination of FREE RTOS and Low Power Gateway on STM32 can be achievable in ST platform, please guide.
