Hi,I am trying to use SPI6 transmission with GPDMA on STM32H7S3L8.While Tx transfer works with simple IT handling, it doesn't work with DMA. No way...To take things simple, I am trying a simple burst transfer (I will leave linked list for later), so ...

Hi,I am using an STM32H7RS MCU (NUCLEO-H7S3L8) and I need to use both USB HS Device and Ethernet MAC.For Ethernet MAC I will only need to use MDIO interface, so I don't think I need a stack for it but please correct me if I am wrong.The MX_ETH_Init c...

Hi,I am testing the USB HS Device CDC implemented from the CDC example (so using ST middlewares) and I notice a strange behavior while reading transfers of 512B.Internally, the function CDC_Receive_HS file Appli/Src/usb_cdc_if.c has been adapted for...

Hi,I want to setup USART3 TX transfers using GPDMA, however, without success.For such purpose I also followed this article: https://community.st.com/t5/stm32-mcus/how-to-configure-the-gpdma/ta-p/49412STM32CubeMX setup is:USART TX DMA ChanThe code for...

Hi,I am trying to setup an USB HS CDC example with NUCLEO-H7S3L8.After setting up the projects for both CDC_Standalone and NUCLEO-H7S3L8 board example (for the latter I manually enabled the USB HS Device from CubeMX), I successfully ran each example ...

The problem seems to be given by the clock.Setting the ETH_CLK pin as very high frequency the clock waveform is correct and the ETH and USB both are brought up.s.
