I am working on Ethernet in STM32H745 MCU. How to assign a different MAC address to 100 MCU so that they can work together on LAN? Further how to filter ethernet packets having a particular MAC address?

I am working on Ethernet in STM32H745 MCU and using STM32CubeIDE. I want to connect 100 such MCU to LAN. How can I assign a different MAC address to all the MCU? Do STM MCUs have a built-in MAC that I can use, or is there any other method to assign d...

I am having trouble making a USB-CDC host work on a STM32F407 chip. The primary problem is it seems to get stuck in an endless loop in the CDC state ENUMERATION. I originally built the code using the STM32Cube application.

I will mention at this point that I am connecting to a known working CDC device. I know it is working because I can connect the same port to a PC, and it enumerates properly, and I can pass data to/from the device.In module usbh_core.c function USBH_...
