How do I generate a calib.localhost file?

[tflc-gonzo]

Hi,

I want to run Photon on my Total5200 with QNX 6.3. To install the
touchscreen driver I need a calib.localhost file. But if I try to generate
the calib.localhost file following happens:

Photon -v

Photon: server running.

calib &

Photon: Photon Open (phid=2)

If I try to start the touch-screen driver following happens:

devi-mpc5200 spi

Error: No such file or directory - cannot open calibration file for
absolute filter module(/etc/system/trap/calib.localhost)

Error: unable to find a graphics region

Error: cannot connect to Photon device

The 1. Error is clear, I need the calib.localhost file, but what mean the
next two errors?

What did I wrong?

calib.localhost file is created by the “calib” utility. Check calib document for details.
Shouldn’t you start the photon using “ph” instead of “Photon -v” ?

[tflc-gonzo]

I think on the total5200 I have to use Photon instead of ph. That’s an abstract of the Documentation:

When you run Photon in a desktop environment, you simply type ph to run a script that does all the work for you.

In an embedded environment, you’ll need to perform all these steps yourself manually

Step 2. Start the Photon server

If you don’t need to pass any command-line arguments to the Photon server, you can start it as follows:

Did you actually get the Photon running? You are in GUI or still on the text console?
You need to make sure Photon is running correctly first.
qnx.com/developers/docs/mome … embed.html

I assume you have run the inputtrap and got the /etc/config/trap/input.X file? quote from the calib doc:

The calib utility is used to calibrate a touchscreen. Once the touchscreen is successfully configured (i.e. you’ve created an input.node file), it must be calibrated.

If I try to start the touch-screen driver following happens:

Sounds like your Photon is not running properly. You need to read the doc.

Even without the calib.localhost, your touch-screen driver should still run fine. You can later run the “calib” to calibrate it. calib will create the calib.$HOSTNAME and a restart of the touch-screen driver will pick it up.

Hi I’m still on the text console over serial connection. What do you mean with inputtrap?
How can I test if my Photon is runnin properly?

[noc]

text console over serial connection? My understanding is Photon requires a graphics card and probably won’t work over serial.

On the Total5200 I have a touch-screen, but to communicate with the Total5200, I have a text console over serial connectin.
