SPI GPIO control - AFCNTR bit with LL API

heveskar · ‎2025-07-16

When using SPI LL API on STM32H7, we want to use the CFG2[AFCNTR] bit. When “Master Keep IO option” is used in the IDE, Cube does not generate the LL_SPI_EnableGPIOControl() function call so that the bit remains unset. This has then has to be called from the user code. Is this a known behavior or a bug?

Reproduction steps are simple, when HAL is used for the SPI initialization the bit is set correctly, while when it is changed to LL, it is not set.

Reproduced on: Nucleo-H723ZG

STM32CubeIDE: 1.19.0

Package: H7 1.12.1
