Correct power sequence? MCU then Display or Display then MCU?

Hi Folks,

Is there a recommended power-up sequence for a system using a STM32 micro and a 7" LCD display that uses a 4 wire SPI?

I’m using a Nucleo-H7A3ZI-Q board and a 7" LCD display with a built-in RA8875 controller.

I think I saw a message here that mentioned that the micro should be powered on before the display gets turned on. I’ve looked everywhere and can’t find the original post that explained this. Can someone point me to that original post? I need to send it to my boss to help me explain the power sequence be fore he approves the schematic and PCB layout.

Thanks,
Richard
