I have initialized SPI4 in STM32H7 controller, but the controller is not transmitting any signal. The other SPI ports i.e SPI2 and SPI3 ports are working fine in 8 bit mode. Please support us to solve this issue.

If you are working the same problem at the same company, please use a single thread, saves explaining the same stuff twice

Review the code

Review the Reference Manual and Data Sheet

Review the peripheral, clock and GPIO settings in the Debugger for coherency to the above

I guess you are not using the current version of HAL.

There were issues but there are solved.

SPI4 works perfect with the current firmware.
