DFP file?

Which QSPI chip are you using?

Which pins does the QSPI chip use?

What tool chain are you using? Keil?

Hi,
We are using STM32h745XI board with external memory. But the DISCO board has two QSPI flash 64MB each and total of 128MB. Where as in our custom board we used only one chip as 64MB.
But in the project file there is no flash algorithm file for 64MB only 128 MB with 745I-DISCO board is available.
Can you provide flash algorithm for 64MB of STM32H745 Disco project.
Regards,
narendar

Posted the last update on Sunday, tested on the H745XI-DISCO using a single-up configuration
