[STM32H750ZB][FMC] FMC_NBL0 and FMC_NBL1 are not considered in CubeIDE1.19.0

Hello,

I am using STM32H750ZB variant for an HMI custom project and I am using SDRAM via FMC.

When I configure FMC in cubeide1.19.0, I can't see the FMC_NBL0 and FMC_NBL1.

I can actually add these pins as GPIOs, but I can't define the AF as AF12_FMC.

I know from the datasheet that this package supports it but I want your confirmation as I still don't have HW to test and don't want to change the package again and redo the HW.

Thanks,

Ayoub

It was my mistake! I didn't check the 16_bit byte enable option!

Hello,

1- The latest version of CubeIDE is 2.1.1. Meanwhile, starting from Cubeide 2.0.0 it's no more possible to configure your application starting from CubeIDE but rather to start it from CubeMx: please read this article: STM32CubeIDE 2.0.0 workflow tutorial

2- So you need to verify the behavior on the latest version of CubeMx.

I'll try it in the latest version and let you know if I face the same issue!

Note that the current version is 2.1.1 - so you're a bit out-of-date.

Note also that, from v2.0.0, CubeMX is now entirely separate - it is no longer included within CubeIDE:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
