Hi,I'm trying to use a SMB alert on a STM32F746NGH6TR. Interestingly, the corresponding interrupt is not getting triggered. I already figured out that the interrupt works if I put the signal on PA9, but it doesn't work on PH9. I already checked for b...

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 ...

I have just updated the Cube Programmer to 2.9.0, which solved an issue with the secure area (https://community.st.com/s/question/0D53W00001EEzsmSAD/unable-to-configure-secure-area-on-h735). I kind of hoped so, as the secure area configuration was me...

I'm trying to configure a secure area (HDP) for a H735. To do so, I am following the steps described in AN5601 HDP secure area for STM32H7B3xx microcontrollers using the examples HDP_Appli and HDP_Boot for the STM32H735G-DK. The application note does...

Incorrect level meant in our case that the RST pin was not pulled down correctly to ground, therefore the PHY did not reset. I recommend using a voltmeter or oscilloscope and measure the voltage of the nRST pin during the reset procedure.In our case ...

I think it was a LAN8720AI, but I am not totally sure anymore.

Hi Imen,as I wrote, I already checked the external clock. At least according to a visual inspection with the oscilloscope it was fine.In the meantime a colleague figured out that the Ethernet Phy had an incorrect level on its reset pin. I still do no...

An Upgrade of the Cube Programmer from 2.7 to 2.9 (which came out a few days ago) solved the issue with the example projects. Therefore, I should probably also be able to do this in my application code. Although I am still uncertain what I am doing w...
