Interupt issue in SPI Communication for STM32U585 boards.

[nirupama_venugopal]

Hello ST Community,

I am currently attempting to establish communication between two STM32U585 boards using the Serial Peripheral Interface (SPI) protocol.

Issue Encountered: Data is not being received.

The transmission from one of the STM32U585 boards is functioning correctly, as confirmed by testing with a logic analyzer. However, the issue lies with the reception on the other STM32U585 board. We have tried both the polling method (which resulted in a timeout error) and the interrupt method (where no callback was received) for SPI communication.

I would appreciate any guidance or suggestions to resolve this issue.

Thanking you,

Nirupama

Ensure slave is ready to receive prior to the master sending a frame. Ensure pins are connected appropriately. Show your code.
