Hello @shiva_chary,

You can do this tutorial : 6. External addressable flash | TouchGFX Documentation
It explains how to configure an QSPI.

Hello @shiva_chary;

Could you please give more detail about the issue?

I recommend you referring to

STM32CubeH7/Projects/STM32H750B-DK/Examples/QSPI/QSPI_MemoryMappedDual at master · STMicroelectronics/STM32CubeH7 · GitHub example and check your configuration. This example describes how to erase part of the QSPI memory, write data in IT mode and access to QSPI memory in memory-mapped dual mode to check the data in a forever loop.

Thank you.
