STM32F767 : No Ethernet when APB2CLKDivider = RCC_HCLK_DIV8 or greater

My SysClock is 200 MHz, AHB Prescaler=1.I want to slow down some timer to filter glitches from external input.But when APB2 peripheral clock is set lower than 50 MHzthe Ethernet DMA does not send any data: no ARP, UDP or TCP.Even when ABP2 timer cloc...

Corrupted ETH Rx Buffer in STM32H7

Hello everyone,I'm running a webserver on a STM32H7. Code was generated with CubeIDE 1.5.0, using LwIP V2.1.2 and the Firmware-Package V1.8.0. So far, I had no problems receiving or transmitting smaller files, in the x-xx kB range from the MCU to a c...

[STM32F769I-EVAL] Can I use both the Audio and Ethernet functionalities at the same time on an application?

So this question arises because the jumpers 3 and 6 of the board switch between either Audio or Ethernet, and I'm not sure in what capacity they're mutually exclusive or not.As an example imagine an application for audio streaming over Ethernet:can I...

Hello Experts Could anyone suggest me how to convert the raw PCM values received in log file be to mp3 or .wav formats .And if there any libraries that could be included or any method? after conversion storing that into sdmmc and play that as loopback?

The Acquired PDM signal is from VM3000 mic and PDM2PCM conversion using stm32f745?could the acquired values be played as loopback to verify whether the acquired sound is in audible frequency to human ears? How could this be validated? all suggestions...
