→Running the OpenAMP_TTY_echo example
For more details, please see the [https://www.st.com/en/embedded-software/stm32cubemp1.html STM32CubeMP1 firmware] documentation and the associated [https://github.com/STMicroelectronics/STM32CubeMP1/tree/1.6.0/Projects/STM32MP157C-DK2/Applications/OpenAMP/OpenAMP_TTY_echo source code].
==Running the OpenAMP_TTY_echo example==
The example is automatically built by Yocto. To run it, please issue the following commands on the target's Linux console:
<pre class="board-terminal">
root@desk-mp1:~# cp /usr/local/Cube-M4-examples/STM32MP157C-DK2/Applications/OpenAMP/OpenAMP_TTY_echo/lib/firmware/OpenAMP_TTY_echo.elf /lib/firmware/
offline
root@desk-mp1:~#
</pre>It is worth remembering that it is also possible to start the CM4 firmware before the Linux kernel is started.
