Question
________________________________________________________________________
There is some problem with Photon's utility starting. For example, I try to start phcalc and got:
# phcalc
Ap: Unable to open resource file
(/proc/boot/phcalc)
And phcalc in image has size
# ls -l /proc/boot/phcalc
-rwxrwxrwx 1 0 0 48253 May 20 2009 /proc/boot/phcalc
But the real size is:
# ls -l /tmp/phcalc
-rwxrwxrwx 2 0 0 83455 Jan 01 00:14 /tmp/phcalc
And it works fine from /tmp (/dev/shmem).

You need to check for the +raw attribute.
[+raw] # Don't strip usage, debugging or
othello # Photon resources from binaries
[-raw] esh # Only esh is affected
pwm # Still affected by +raw flag
pfm
[-raw] # Turn off +raw, since shared objects
libphrender.so # can't be shared if +raw is enabled
libph.so
[+raw] my_ph_app # We want Photon resources for this
# file only. The -raw flag is
# still in effect for other files.
libc.so # Still affected by -raw flag
...
Doit with your phcalc Photon app.
