SPI frequency problem

Hello guys.


I'm working with master-slave SPI communication by interruption (SPI1_IRQHandler). It was working fine with a frequency of 2 MHz, but I got to change the frequency because of the electrical noise to 100 kHz. And now, it doesn't work because when the slave is sending 0x00, master is reading 0xFF.


 


How could I solve this?


Thanks
