== Introduction ==
This article describes the process of loading FreeRTOS images into memory, and running the in-memory images. For quick evaluation, the FreeRTOS BSP comes with precompiled images that can be found under the {{filename|images}} folder.

== Loading FreeRTOS into memory ==
A FreeRTOS image must be run from TCM, DDR, or OCRAM, depending on how it was built. Consult the following table for the right <'''load_addr'''> to use:
{| cellpadding="3" border="1" style="border: 1px solid rgb(85, 85, 85); border-collapse: collapse;"
|-
! Image name
! Must run from
! load_addr
|-
| <image_name>.bin
| TCM
| 7F8000
|-
| <image_name>_ocram.bin
| OCRAM
| 910000
|-
| <image_name>_ddr.bin
| DDR
| 9FF00000
|}

* Power on the module and stop U-Boot from booting Linux by holding Ctrl-c.
* Place the demo image into USB drive or SD-card, and connect it into the evaluation board.
* Use the following U-Boot commands to load the demo image from USB storage:
<pre>
CL-SOM-iMX7 # usb start
CL-SOM-iMX7 # load usb 0 <load_addr> <image_name>
</pre>
* Use the following U-Boot commands to load the demo image from SD-card:
<pre>
CL-SOM-iMX7 # mmc dev 0
CL-SOM-iMX7 # mmc rescan
CL-SOM-iMX7 # load mmc 0 <load_addr> <image_name>
</pre>

== Booting FreeRTOS from memory ==
* Run the image using the following commands:
<pre>
CL-SOM-iMX7 # dcache flush
CL-SOM-iMX7 # bootaux <load_addr>
</pre>
