@Shrini-007 Please rework your issue description. Having an image makes this quite hard to read (and potentially impossible for people with strong visual impairment). Please provide usual text (you can add images, but don't abuse of it).

Sorry, for inconvenience....So here it goes I am working on the external flash on QSPI interface. I am able to read/write the external flash successfully by using interrupt method. Now I am trying the same with DMA, but as soon as I build my project after enabling the DMA in .dts file I am getting this error.

Error Message end.

Here are my .dts configurations for external flash. I have done this in proj.conf file CONFIG_DMA=y. I have attached the Kconfig.stm32_qspi file also for zephyr version 2.7.2

I am not able understand what does this error mean….& what I am missing.

NOTE: I am using STM32H743 board for interfacing it with external flash & zephyr version is 2.7.2

@Shrini-007 I'm converting this to discussion, since for now that's rather a question than a real bug.
