I still don’t know why you go through all the bother
a. the port is already done 
b. Volumio2 is obsolete since 2020 and unsupported
c. you will hardly find anyone else here who wants to or can help
I predict a few big stumble blocks on the way. Example: running a 32-bit OS on a 64-bit needs a few specific requirements for the kernel and the build script, which you will not find in the C1 script.
Good luck with it in case you insist, you’ll need it. And even then, you will have a basic version without myVolumio. You are aware of that, right?
Anyway, this is is where my support also stops, sorry.
