The SPI1 clock line is not working on the NUCLEO-F334R8 board

Hi,

I am trying to get the above named board to work with an ILI9341 based display. But it is not working. I took a look at the SPI lines with a logic analyser. I saw that there was no activity on the CLOCK line. I switched to an alternative pin for the CLOCK signal but I did not get any result.

What could be wrong? Please find attached a copy of my project files for you to take a look at.

Thank you.

Have you checked the board's User Manual and/or schematics to see if there is anything else using that pin?

Can you toggle that pin just as a basic GPIO?

Is there any activity on any other line(s) ?

Please post the schematic of how you are connecting the "ILI9341 based display"
