Embeded Photon question

I have boot from doc.Now I want to run my phab programe in doc.Then I add this :stuck_out_tongue:hoton;phfontFA;io-graphics.
But something is wrong with phfontFA,I do as the help about Photon embede.
This is the result:
use phfontFA:could not find font type to attch(assumably)
use fontsleuth :attach photon error-phAttach failed

Who can give me an advise or give me a photon sample?

Wanna post your build file / boot script?
