Hi all,
We have a question regarding the external memory interface connected to XSPI1 on the STM32H7S7Z8J6. We use the APS6404L-3SQN-ZR 64Mb external ram. We activated the XSPI interface with the following parameters:
We also created the memory partion inside the memory view:
In the boot partition we try to read and write some values to 0x90000000 but the void MemManage_Handler(void) is called immediatly. We measure the XSPI bus but there is no activity to be seen. So it seems like we are missing some vital settings. Are there any suggestions what to check?
Best regards
