Memory controller (MEMC) driver¶
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:
west build -b mimxrt595_evk_cm33 samples/drivers/memc west build -t run
To build for another board, change “mimxrt595_evk_cm33” above to that board’s name.
* Booting Zephyr OS build zephyr-v3.2.0-2686-gd52d828c2bdc * Writing to memory region with base 0x38000000, size 0x800000
