Prerequisite: First you must know that the port is not independent, it is dependent on the process. When a process is turned on, its corresponding port is turned on and the process shuts down, and the port is closed. The next time a process is turned on again, the corresponding port is turned on again. Instead of purel

ECOS application can be started without Redboot boot, and can be directly started from the Internal flash of stm32. I recorded this porting process as an article and posted it on my blog. Because there is a lot of content, I will not post it here. If you are interested, you can go to my blog to learn about it. The following is the link:Port ECOs with stm32#7.
