Issue with STM32F7 SPI interface

Question asked by maheshwar reddy on Nov 10, 2017

I am using the STM32F765BIT micro controller(208 pin package) in our custom board, I am using STM CubeMx generated code. I have selected two SPI (SPI1 & SPI2) interface both are with same configuration. with SPI2 I can able to access external SPI-device (both read write is working).

But when I tried with SPI1 I can't able access same device . I also cross checked the signal levels of SPI1 interface , No signal is coming (CS,CLK,MOSI). 

Is there any additional configuration needed to use SPI1 interface. Can you please give some brief details regarding this.

 

Thank you

 

Best regards
