Resolved! SWR bit of ETH_DMAMR does not get reset by hardware

I have to examples of a PCB with a H735. On one of them HAL_Init for ethernet fails due to the SWR bit of ETH_DMAMR not getting reset by hardware. On the other example of the PCB everything is working fine, running the exact same binary.Usually this ...

STM32f207's MII with Marvel's MII

Hi All, I'm developing a project, in which I've connected the MII port of STM32F207 with Marvel IC 88E6060 (Ethernet + fiber switch) MII port 5 but the firmware support (SPL for STM32F2XX) provides libraries for DP83848 PHY only. Hence, if I...

Choose connector and Ethernet Transceiver for MCU ethernet interface.

Hi, I need to add an ethernet interface to a STM32H745IIT6 MCU. I have to choose the RJ45 connector and the Ethernet Transceiver chip.I state that I've never done this thing, so my idea was to take the Nucleo board schematic and use the same connecto...

the component LAN8742AI-CZ LAN use in your design board is very difficult to buy. Do you have an alternative?

H7-ETH-USB bridge dilemma - electrical connections

Hello circuit designers and PCB guys,I have a problem of how to connect the H7 ethernet via a PHY and a ethernet USB bridge.to the outside world:ethernet connection via RJ45 to hostUSB connection to host (e.g. laptop without ethernet)I must NOT use t...

STM32H743ZI2 NUCLEO board Ethernet doesn't work when moving to JP5 to 1.8V (MCU_VDD)

Hi All,I use the STM32H743ZI2-NUCLEO board with JP5 on 1.8V for MCU_VDD.Running the LWIP example, the Ethernet doesn't work (It does work when running with 3.3V).Any idea how to make it work with 1.8V?Thanks,David

STM32F429 interferes with GPS signal reception.

Colleagues, I made a PCB project that contains Ethernet, GPS and STM32F429. but there was a problem. that GPS actively loses satellites when Ethernet is connected. I use RTOS and LWIP. I don’t know how to explain this ... capacitors - filters, did no...

RMII GPIO state after HAL_ETH_Init()

Hi,we have a PHY with several bootstraps. Some of them are shared with the RMII from a STM32H753 (see image below, controller is on the left).A FreeRTOS+TCP network stack is used, which, when rebooted, first does some low level inits with HAL_ETH_Ini...

Resolved! STM32H745XI Discovery and Ethernet physical connection

Hi,I am trying to use Ethernet with STM32H745XI Discovery board and try to find out, if default board configuration can be used or I need to redirect Q-SPI to pints to Ethernet. Unfortunately the documentation description is not clear - should be thi...

I need to create a USB & Ethernet tester. The USB must be a virtual serial port and Ethernet must initiate pinging. I am using Mikroelectronica products but am having trouble. What ST products are available (Discovery board?) that can do the job?

Currently using the MikroE EasyMx Pro V7 with the STM32F407VGT6 processor. I cannot get that to work on the Ethernet side. I'd like to switch to an ST product such as the discovery board for this processor but I'm not sure if it's the right thing for...
