I would like to communicate between STM32F407VE (MASTER) and STM32F303RE (SLAVE) using SPI. I am able to send the data from master but the slave is not able to receive it . Could you guide me through the initial steps I should consider

I have generated the driver codes using STM32Cube MX. I am attaching wth this the source codes of both master(main)and slave (main_F3) microcontrollers.

Could you help me with this

Are pins initialized?

Can you do a scope trace to see if signal is being sent?

Is chip select pin behaving correctly?

Didn't look at the code but that’s where I’d start.
