Issue with HAL_OSPIM_Config() function when using two OSPI ports

DWWelch · ‎2025-09-10

Hello,

I noticed an issue with the HAL OSPIM initialization code when initializing two OSPI ports. The first port initializes correctly, but when initializing the second port the HAL_OSPIM_Config() function does not re-enable the first ports signal lines. So the second port works, but the first port signals are disabled. I am using STM32H7A3 MCU and STMCube STM32H7 V1.12.1.

Thanks,

Dan

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.
