I have two NUCLEO-H755ZI-Q boards and I’m trying to run the SPI_FullDuplex_ComIT example on both.One board breaks here (whether the software is built for master or slave):The other board has no problem (whether the software is built for master or sla...

I have a read-only SPI master. Here’s the code: SpiHandle.Init.Mode = SPI_MODE_MASTER; SpiHandle.Init.Direction = SPI_DIRECTION_2LINES_RXONLY; SpiHandle.Init.DataSize = SPI_DATASIZE_16BIT; SpiHandle.Init.CLKPolarity = SPI_POLARITY_LOW; SpiHandle.Init...

I got a NUCLEO-H755ZI-Q board and downloaded all the docs and software (en.stm32cubeh7-v1-12-0.zip).When I go to C:\STM32Cube_FW_H7_V1.12.0\Projects\NUCLEO-H755ZI-Q, there’s just a read.me file that says: “All projects available under Projects\NUCLEO...

I can get HAL_SPI_Transmit (and HAL_SPI_Transmit_IT) to work properly, but I cannot get HAL_SPI_Transmit_DMA to output signals. Here's my simplified code.

Enabling CM4 was erroneously marked as the solution. Disabling it was just an experiment. We still don't know why the synchronization times-out on one of my boards.

I left the while loop and commented out the error handler so it falls through:It now works! Thanks for your help!

It was originally enabled. I disabled it to see if that made a difference.
