I'm trying to enable the shell subsystem over the uart console on my board with no luck.
I built the samples/subsys/shell/shell_module/ application and added some printk() to it just to see that the console is working, and indeed the printk works.
I don't get any prompt, or any other interaction with the console.
Any idea what am I doing wrong?In general, I'm trying to understand how the shell works. Is it running as a separate thread along side with my application thread?
Is it running in kernel mode, or userspace?
Your insight is appreciated.
