Hi All,

I followed the Getting start guide. At the stage, "prepare your mangOH board for your development "  
when I give the command make wp\_76xx , i get the following errors . DO I miss something here ?

Makefile:86: ==== OCTAVE\_ROOT not defined ====  
Not building LEGATO due to $LEGATO == 0  
make: /home/mangoh/legato\_framework/legato/bin/findtoolchain: Command not found

# NOTE: When using leaf, these TOOLCHAIN\_X variables don’t need to be passed to mksys.

seems you need to first go to the legato framework, and type “. ./configlegatoenv”  
e.g.

owner@CNHKG-EX-001367:~/legato/packages/legato.framework.18.10.3.wp76xx-201903041257/resources/legato$ pwd

I have the same problem, and I have solved , typing “leaf shell” , before make command.

this works:

cd ~/myWorkspace  
leaf search -t mangOH -t red -t wp76xx  
leaf setup p1\_red76 -p mangoh-red-wp76xx\_0.5.0  
leaf shell  
make red\_spk
