Is someone has a simple example of Hyperbus protocol under STM32CubeIDE?

[AGEBE.1]

Hi,

I have really hard time to develop an Hyperbus protocol application on NUCLEO-L4R5ZI-P, the instruction is sent but the data are sent in a non-periodic sequence and DQS doesn't rise at the good time.

Is there someone who has develop the most simple application of Hyperbus communication that he could share with me?

I have tried to understand the exemple provided in that following link without success.

Thank you in advance for your help,

Kind regards.

@AGEBE.1​ , I have not really tried HyperRAM myself. But, it seems there are two reference projects regarding HyperRAM inside STM32H7 FW package which may be helpful:

• STM32Cube_FW_H7_V1.9.0\Projects\STM32H735G-DK\Examples\OSPI\OSPI_HyperRAM_MemoryMapped\OSPI_HyperRAM_MemoryMapped
• STM32Cube_FW_H7_V1.9.0\Projects\STM32H7B3I-EVAL\Examples\OSPI\OSPI_RAM_MemoryMapped
