| 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. |
| |
