Hi
I am playing Total5200 with Photon. It can display basic photon
application but the touch screen doesn’t response at all.
following is the setting in my build file
Photon
waitfor /dev/photon 10
io-graphics -ds1d13806 xres=640,yres=480,bitpp=16,photon -pphoton
waitfor /dev/phfont
display_msg Starting TouchScreen
devi-mpc5200 spi
it always shows following errors
Error: No such file or directory - cannot open calibration file for
absolute filter module(/etc/system/trap/calib.localhost)
Error: found graphics region with no capabilities data
Error: No such file or directory - cannot open calibration file for
absolute filter module(/etc/system/trap/calib.localho
st)
I can run calibration
#calib
and it shows the menus to calibrate the cursor but the touchscreen
never response. I have /dev/photon, /dev/phfont in system
Does any body has similar experience? Maybe someone can post a full
build file for Total5200. The one coming with Total5200 is too simple
and it doesn’t support Photon. After adding some font setting based on
doc
“Photon in Embedded system” finally it begins to work. But it took me
a couple of days. I am thinking why motorola could not give a better
technical support for these Total5200.

Are you running the spi manager (spi-mpc5200)?

Note: You must this manager before starting the touchscreen driver.

Hi Joe
Thank you for your reply. I do run spi before start Photon server. I
think spi works properly. Otherwise I can not see Photon application
running on the screen because the display is also using SPI, I
think.

Hello,
I just started playing around with the Total5200 system and I have the
exact same error: “Error: found graphics region with no capabilities
data”. the systems does nothing after that and nothing else is
displayed
But my touchscreen works and the pointer seems to respond. Also, i can
run photon application like phcalc.
Could you please let me know how to go about resolving this issue ?
thanks,
Nithin
