Info on System startup - custom startup

Hi ,

I wanted to perform a custom startup and started reading this System Startup · PX4 Developer Guide (see section ‘’ Replacing the System Startup’ ) .In that it says to paste rc.txt in etc folder of microsd card.
I inserted the sdcard on windows 10 platform but there was no /etc folder available.

How do I access the '/etc ’ folder ? Is it through ubuntu operating system that i will be able to access the folder.?

You can just create it yoursef, even in Windows

Thanks for the reply.
Do you mean to say that i should manually create a folder etc in my sdcard ? and paste rc.txt in that folder.

Yes, you need to create it manually

Thank you so much for the info.
