== Introduction ==
This article describes the process of loading FreeRTOS images into memory, and running the in-memory images. For quick evaluation, the FreeRTOS BSP for CL-SOM-iMX7 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

=== Loading from USB ===
* Power on the module and stop U-Boot from booting Linux by holding Ctrl-c.
* Place image into USB drive, and insert the USB drive into the P6 or P26 USB connector.
* Load image into memory:
<pre>
CL-SOM-iMX7 # usb start
CL-SOM-iMX7 # load usb 0 <load_addr> <image_name>
</pre>
To boot the image, go to [[CL-SOM-iMX7: FreeRTOS: Demos#Booting FreeRTOS from memory | Booting FreeRTOS from memory]].

=== Loading from MMC ===
* Power on the module and stop U-Boot from booting Linux by holding Ctrl-c.
* Place image into SD-card, and insert the SD-card into the P9 connector.
* Load image into memory:
<pre>
CL-SOM-iMX7 # mmc dev 0
CL-SOM-iMX7 # mmc rescan
CL-SOM-iMX7 # load mmc 0 <load_addr> <image_name>
</pre>
To boot the image, go to [[CL-SOM-iMX7: FreeRTOS: Demos#Booting FreeRTOS from memory | Booting FreeRTOS from memory]].

=== Loading from TFTP ===
* Power on the module and stop U-Boot from booting Linux by holding Ctrl-c.
* Setup TFTP as described in the [[Linux: Setting up a development environment]] article, and place the image into the TFTP folder on your workstation.
* Connect CL-SOM-iMX7 to a network using connector P21.
* Load image into memory:
<pre>
CL-SOM-iMX7 # setenv autoload no
CL-SOM-iMX7 # dhcp
CL-SOM-iMX7 # setenv serverip <your_workstation_ip>
CL-SOM-iMX7 # tftp <load_addr> <image_name>
</pre>
To boot the image, go to [[CL-SOM-iMX7: FreeRTOS: Demos#Booting FreeRTOS from memory | Booting FreeRTOS from memory]].

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