Questions Regarding QuadSPI in STM32MP13 Bare Metal

Currently, I am testing QuadSPI.

Is it correct for the output to include Command / Address / Data?

I want to output only Data. While I can remove the Address through settings, I couldn't remove the Command.

Is it possible to output only Data?

Hi @SL1 

QUADSPI is build to interface external Flash or similar.

For you concern, did you try playing with IMODE setting ?

Hi, I recently solved this problem.

After checking, it was due to the ClockMode in the code below.

When I changed that part to XSPI_CLOCK_MODE_0, it worked correctly.

Is it correct that if it is set to XSPI_CLOCK_MODE_3, the address should be output before the data is output?

I will finish the post after confirming the answer.
