Hi, thanks for your answer but I think this is not really what I need. I need a way to configure and change the variable values at runtime. The envfs with the loadenv and saveenv commands is OK, what I'm missing is a way to 'edit' the environment before I can save it back to the persistent storage. I'm thinking about adding some options to printenv to let it dump the variables given on its command line to a file. giorgio > On September 29, 2017 at 11:27 AM B Gol wrote: > > I just put all the variables in the source directory and then compile again. > Look inside the following dir and its sub dirs, you'll see all the default(hard coded) > variables inside it: > > /source-path/barebox-yyyy.mm.d/defaultenv/ > > Simply make a text file inside a sub dir.The file name would be your variable name and > the string inside the file would be the value for that particular variable. > > On Friday, September 29, 2017 12:20 PM, Giorgio Dal Molin wrote: > > Hi, > > I'm working on a new project with an embedded system based on > > a standard intel PC. > > I already have a barebox.efi running on the system; my problem is now > > how to permanently save some variables so that, on restart, they can be > > automatically restored by my '/env/bin/init' script. > > The variables I mean are for example 'eth0.ipaddr' or 'eth0.serveraddr'. > > A solution I used in the past was a custom 'env_dump' command that generated > > a config text file like: > > eth0.ipaddr=10.0.0.15 > > eth0.serveraddr=10.0.0.1 > > ... > > Then I saved the file with 'saveenv' and restored it back with 'loadenv'. > > Is there a better way to solve this problem ?
