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.

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.
