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 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:
| 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:
CL-SOM-iMX7 # usb start
CL-SOM-iMX7 # load usb 0 <load_addr> <image_name>
- Use the following U-Boot commands to load the demo image from SD-card:
CL-SOM-iMX7 # mmc dev 0
CL-SOM-iMX7 # mmc rescan
CL-SOM-iMX7 # load mmc 0 <load_addr> <image_name>
Booting FreeRTOS from memory
- Run the image using the following commands:
CL-SOM-iMX7 # dcache flush
CL-SOM-iMX7 # bootaux <load_addr>
