Looking for LL driver for interfacing with Octospi for STM32H5 series

2 replies

Hi all,

We are currently using the stm32h5-hal-library in our project. Our preference is to use the LL drivers rather than the HAL and for the Octospi, we only see a HAL drive for it (stm32h5xx_hal_xspi.c). Is there a LL driver equivalent for this? I have also tried generating the code with STM32CubeIDE and didn't see an option to switch to the LL driver as I normally would for other peripherals

Thanks in advance.

Hello @HuyDang and welcome to the community.

Unfortunately, there is no LL driver for XSPI.

All peripherals supporting LL have a driver with a file name having ll in the middle: stm32h5xx_ll_(name).c:

Look at the driver folder:

https://github.com/STMicroelectronics/stm32h5xx_hal_driver/tree/7e8c7d8e91c15321864f513f8458ce7f6555eb4e/Src

there is no stm32h5xx_ll_xspi.c file there.
