NUCLEO_F746ZG LAN stops working after few days.
Port, board and/or hardware
NUCLEO_F746ZG
MicroPython version
Micropython v1.17
Reproduction
Just using it for a while.
Expected behaviour
To continue communicating.
Observed behaviour
This happens randomly. It can happen after 1 day or after 20 days. The code continues to work.
Additional Information
Micropython stops communicating with the LAN chip. I have no way of resetting the chip. I tried to reactivate the LAN driver. I also tried extending the C part of the LAN driver and look at the registers but did not find a solution there. Resetting the micropython solves the issue. I guess the LAN chip also gets a reset. Is there anything i can test or extend to find out what the issue is and how to fix it. Thanks.

SD card Nucleo_F746ZG
Hi
I have been testing Micropython with some STM32 Nucleo Boards and adding SD card functionality by wiring an SD card directly to the board and modifying mpconfigboard.h accordingly as per below link.
https://www.kaltpost.de/?p=2199
I have done this successfully with F401RE and L476RG and can run python scripts from the SD card.
I have tried this also with a Nucleo F746ZG modifying mpconfigboard.h in the same way but with no success.
on start up I get the warning PYB: cant mount SD card.
I noticed in the pins.csv file for the F746ZG there were no SDMMC pins listed so I had to add them manually in order to compile which would suggest that SD card functionality has never been tested for this particular processor.
logic analyzer shows clock signal and cmd data but no data on any of the data pins.
The Not working F746ZG clock signal is 400KHz for a short period and then stops.
The working F401RE shows clock signal of 400 khz then 8MHZ when it starts to transfer data from SD Card.
has anyone else attempted this with this particular board/Processor?
