When I load my application to target and connect to ssh via usb interface and type list of available process:

$ps -aef

I can see a process name associated with my application defined in .adef. How Legato framework do this? As we know that all linux process is created from a system call fork(). So where and when this process is created?

Thank you @jyijyi , but still can’t fiure it out. In link you gave, the fork() is called in file process.c from a function le\_proc\_Execute(). However, I could not see in my application workspace anyone calling this function. Nor in platform code in ~/.leaf folder.
