Issue with STM32F7 SPI interface

[MANISH]

Posted on November 10, 2017 at 08:05

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

Hello

‌,

SPI1 and SPI2 should work normally. To proceed, please share with us .ioc file and describe which pins are used for SPI1 and SPI2 peripherals.

Thank you,

Best regards,
