OpenAMP load fw Sample Application¶
Overview¶
This application demonstrates how to use OpenAMP with Zephyr. It is designed to demonstrate how to integrate OpenAMP with Zephyr both from a build perspective and code.
Building the application for csk6¶
# From the root of the zephyr repository
west build -b csk6 samples/boards/csk6/subsys/ipc/openamp_load_fw
west debug
Open a serial terminal (minicom, putty, etc.) and connect the board with the following settings:
Speed: 115200
Data: 8 bits
Parity: None
Stop bits: 1
Before running this example, you first need to package the remote firmware into the file system and burn it to the corresponding Flash area address. Reset the board and the following message will appear on the corresponding serial port.
