When I use the imx6sx development board to use RPMSG to realize dual-core communication, I found that when I first start the M4 core and then start the A9 core, there is no problem with the dual-core communication. When I start A9 and then M4, there is no response when I load the corresponding .ko file. I saw in an article that it is possible to start A9 first and then realize dual-core communication, so I want to ask whether the dual-core communication of imx6sx can be started by the second method.
The screenshot is the implementation method of the article I am looking for. This article is to start A9 first, then start M4, and finally realize dual-core communication.
Hi!
I saw the content about RPMSG in Chapter 5. I think this chapter is to start M4 first and then start A9 core. Can imx6sx start A9 first and then M4?
