Connectivity to external NOR Flash Memory using DMA of STM32F446RE

[DCont.1]

Hi,

Am trying to correctly connect to my external NOR flash memory using my STM32F446RE's DMA.

Am not sure how to go about this and the libraries I have tried are not working at all.

Here's a link to the library I tried to test the connectivity between my STM32 and my Flash Memory. I wasn't able to get it working.

Additionally, here's the link to the datasheet of the NOR flash memory am using:

The connection scheme I have going on right now is using standard SPI

SPI1_SCK - CLK

SPI1_MISO - DO

SPI1_MISO - DI

(FLASH_CS is a GPIO Output)

FLASH_CS - CS

If you can't debug the code you have, or relate this and perhaps other examples to the intent conveyed in the data-sheet you're in trouble.

DMA isn't going to help here, only complicate things.

I don't think anyone's going to custom code a worked solution here.

So you probably need to start with getting some basic SPI code working, and then a relatively simple interaction with the READ ID type command. Then build upon that.
