Embedded Photon on Pxa270

I am building an embedded photon app but I am having trouble with photon loading correctly.
I am running v6.3, on PXA270.
All runs ok - Disk, Network, serial port etc, but I cannot get photon to start
This is the output of sloginfo.

Any ideas?
What’s missing?

No Font Server is starting





These are used by Photon(and apps) on my system.

How do you start Photon? Are you using phfont directly or letting io-graphics start it? If you let io-graphics start it you need /lib/dll/phfont.so and /lib/dll must be in your CS_LIBPATH. Post your startup script if you like.


when I start pterm.

pterm /proc/boot/ksh &
