Program will not start when on USB power only

[[email protected]]

I have a working program. While the Workshop 4 is running and connects, I can unplug the pixxi and plug it back in and it will start, I do see uart lights blink when plugging it in.

If I plug the device into a USB power adapter or my laptop and the development tool is not running, the program does not start. What am I doing wrong?

Thank you,
Michael

Hi Michael,

Welcome to the Forum,

Could you please click on the Project Tab and check to see if the Destination is set to Run RAM. If it is, set it to Run Flash and then try re-flashing the Pixxi.

Please let me know if this works out for you.

Best regards

Paul

Destination is set to flash already...file system has nothing selected.

I will re-flash and force a recompile. Earlier I had some issues with the program not updating after small changes.

OK. I recompiled and deployed. Here's the scenario:
1. Unplug pixxi
2. Shutdown Workshop
3. Plug pixxi back into laptop...back lighting comes on but program does not start
4. Start workshop but do not load project...program starts

Ideas?

Here's my code if that will help. Additional issue I am running into is that if I let the pixxi sit running, eventually it becomes unresponsive until I cycle power.

I did uncomment this and deployed...no change in behavior.
#MODE RUNFLASH

Hi Michael,

This is really odd.

I have noticed on Line 23. It should be this.

if(media_Init())

And the File system should be set to Flash also.

More information. I have placed diagnostic putstr's to see where the device stops. If powered up and WorkShop is not running, the last debug string logged is putstr("...........1......");

You still haven't fixed the media_Init() as suggested by Paul above

Sorry, I saw the change of the ! operator and completely overlooked the (). That has fixed it. Thank you.

Two additional questions:
1. Who would I speak to to get a quote for the 32MB of the 13P2CT?
2. Has anyone built or provide a back for the 13P2CT that gives just enough room for a battery?

Thank you for your support,
Michael

Good day!

You can email [email protected] regarding the 32MB version of the display.

And the media_init() change did fix the issue.
