I am planning on using the STM32G070, a small 240 x 240 LCD Display and external NOR Flash with TouchGFX. Can I perform DMA Transfers directly from the external NOR Flash Memory to the Display memory? Thanks, Jim Russell

I believe it should work with DMA in the same manner internal FLASH would, only slower.

You can't concurrently write into NOR Flash and read it, or memory map to it. So generally whatever you have in Flash will be static.

I was only planning to use NOR Memory DMA Transfers for full screen updates. Thanks.
