Question

STM32F407 Disc SPI3 initially it's working fine then MISO pin stop working?

I am using STMCubeIDE for my project.

SPI3 connected with PC10, PC11, and PC12  pins but When I connected the logic analyzer with the PC11 pin while reading TMC5160 register it showed nothing. The pin will be high whatever I do.

 

I know this thing not give you a full Idea but tell me anything you want I will share it. B-coz I don't know what info will be useful to debug.

> When I connected the logic analyzer

Then it sounds like hardware damage, it may be on either side (STM32, target, LA) or all.

SCK works?

You can try to bit-bang some basic protocol to exclude any other influence.

Hello @MarkEvens, 

Maybe share your SPI3 configuration/ connection with TMC5160 chip

Look at reasons why the Slave device isn't responding.

Is there a pin controlling I2C/SPI mode, or how chip select is activated.

Is it always doing this or does it work for a period after the power is cycled. How long and what access patterns?

    This is spi initialization and below is my used pins

    Thank you everyone for your support.

    I found a mistake I am using the TMC5160-BoB module which has two separate supply options one is for the motor and the second is named vcc_io.

     

    So I am trying to read from the module without powering the motor supply pins. That is the main power supply for the module. vcc_io is just for resetting the module it is not providing complete power to module :face_with_tears_of_joy:

     

    So as I powered the motor pins it started working.
