STM32H7 DFP 3.1.1 spi issue

[JosepM Ribera]

Hi

we are working with a STM32H7 project. Recently we upgrade the packages and the Keil.STM32H7xx_DFP.2.5.0 grow up to DFP 3.1.1.

Since the upgrading, the SPI start to fail (some data bits were wrong in every reading). Downgrading to DFP 2.5.0 it works fine again.

What could be the problem with DFP 3.1.1? It seems some issue with the project migration...

Hello @JosepM Ribera,

Make sure to upgrade and use the latest releases of CubeMX tool and STM32CubeH7 MCU package.

Otherwise, try localizing where the code hangs, and the kind of message gives.

Share more details on your code generator (with screenshot) this will help to understand your issue.

Keil package DFP 3.1.1 contains CubeH7 library release 1.11.0 (~ December 2022).
DFP 2.5.0 contains CubeH7 library release 1.6.0 (ancient)

There have been some breaking changes since v. 1.6.0 IIRC, in the library and the generator templates. A manual review is needed here.
