MEMC Driver Sample
|
||
|
|
##################

|
|
Overview
|
||
|
|
********
|
||
|
|
|
||
|
|
This sample can be used with any memory controller driver that
|
||
|
|
memory maps external RAM. It is intended to demonstrate
|
||
|
|
the ability to read and write from the memory mapped region.
|
||
|
|
|
||
|
|
Note that the chosen region (set by ``sram-ext`` dt alias node) should not
|
||
|
|
overlap with memory used for XIP or SRAM by the application, as the sample
|
||
|
|
would overwrite this data
|
||
|
|
|
||
|
|
|
||
|
|
Building and Running
|
||
|
|
********************
|
||
|
|
|
||
|
|
This application can be built and executed on an RT595 EVK as follows:
|
||
|
|
|
||
|
|
.. zephyr-app-commands::
|
||
|
|
:zephyr-app: samples/drivers/memc
|
||
|
|
:host-os: unix
|
||
|
|
:board: mimxrt595_evk_cm33
|
||
|
|
:goals: run
|
||
|
|
:compact:
|
||
|
|
|
||
|
|
To build for another board, change "mimxrt595_evk_cm33" above to that
|
||
|
|
board's name.
|
||
|
|
|
||
|
