hi, i m working on SDRAM for H750 Disco board, saw the schematic diagram(enclosed) shows pin PH5 - SDNWE, PH6 - SDNE1, PH7 - SDCKE1. But STM32CubeIDE has the wrong connection PC0, PC2 and PC3 as shown enclosed.
I managed to change the pin of SDNWE to PH5, but PH6 and PH7 were not an alternative pin to SDNE1 and SDCKE1. i tried to use GPIO Pin instead for PH6 & 7 but my code couldn't worked. (the same code worked on STM32F750 Disco board) Could anyone advise what to do

How is a design that demonstrably works flawed?
It uses half the memory as a cost/part saving strategy. Perhaps it's more available long term and interchangeable?
There might be a Cube side issue, that you picked the wrong template, or the template is broken. You pick the right board?

i confirmed its the correct template, correct board H750, the working code is on F750 Disco board. You can try load H750 from CubeIDE..

Hello,
I'm not sure I understandood the case.
I started a new project from Board and selected STM32H750-DK board, Selected to initialize the peripherals and this is the GPIOs selected by CubeMx for the SDRAM:
So nothing wrong here.
Could you please share your ioc file?

this is e board selection, but i still getting the wrong connection PC0, PC2 and PC3.

i can only choose STM32H750B-DK... any difference ?

I didn't understand. There is only one DK board available on the market:
