DMA operation on SPIFI controller

Hi all, I have one question on using DMA on SPIFI controller and wonder if anyone can shed some light on it. When using DMA on SPIFI controller, do I still need to specify bit 5:1 of the configuration for SPIFI if I enable the memory mode?

Thanks

Richard

Hi Richard CHEN,
Thanks for your reply.
Unfortunately, now there's no similar demo as you want in the LPCOpen library, however, you can combine the SPIFI and DMA demos to implement this application.
Note: LPC1820 doesn't have the internal flash if it boots from the SPIFI flash, it's prohibited to communicate with itself, hope this is clear.
Have a great day,
TIC
