Hi, we tried to send raw ethernet packages using a STM32MP157C-DK2. We used this simple C code here: https://gist.github.com/austinmarton/1922600The code works well on Linux x86 systems as well on Raspbian, but not on the STM32MP157C-DK2 [1]: Sending...

We use a STM32F0 in an application with increased safety requirements. The power supply is secured by a simple fuse and we have to assure that the STM32F0 is in reset state when the fuse is blown (EN60335).Since we have a second power supply in the s...

There is an unititialized variable in stlink_usb.c, see https://github.com/STMicroelectronics/OpenOCD/pull/13

Thank you all for the helpful hints! I agree now that we need to add some external components to ensure that the STM32F0 is in reset state when the fuse is blown.

No, unfortunately we need ADC inputs also to be connected to the second power supply, and as far as I see Pins with an ADC option are not Fault Tolerant...

It seems that there is nothing helpful "on chip", e.g. a brownout reset circuit or a separate input, to be used for an undervoltage lockout - or am I wrong?

Sending Raw Ethernet Packages using STM32MP157C-DK2

Is there a simple way to prevent that the STM32F0 is supplied parasitic through the protection diodes of the GPIOs? The device seems not to provide a brownout reset circuit, or am I wrong?
