Any gps will provide a very accurate time report. The output is usually ASCII text
and readable on either the RS-232 serial port or a USB port, depending on the
device chosen.
If one second intervals meet your requirement then this is a quick way to get it.
I have just downloaded and installed the same SDK and bumped into the same problem.
There are static libraries in the directory: .../gp2xsdk/Tools/arm-gp2x-linux/lib/static
but they do not include: libjpeg.a or libpow.a -- both are required to use SDL_image.
Does anyone know a location to...
I have the Mk1 gp2x and I modded the developer BoB by soldering two wires to
the back of the power socket on the Bob. The other end has a plug to match the
gp2x power input. The standard 2.0 amp accessory ac adaptor will drive both.
This mght not apply for the new commercial Bob since there is...
Very impressive design work. Much better than anything I could do.
I have a developer's version of the BoB and a Mk1 Gp2x.
To overcome the need for two power supplies, I soldered a short
wire to the back of the Bob power input socket and attached a
mating plug that gets inserted into the Gp2x...
Rikaline (www.rikaline.com.tw) makes a gps module that fits all inside the antenna.
Cost is around US $ 40. It outputs both RS232 and TTL level signals.
Have a look at sqlite (www.sqlite.org) as your database engine.
It is public domain, written in C and is very fast.
I have plans to do...
This is an interesting idea, but a quick look at the website indicates
that USB support will not be available until version 4.8 sometime in 2007.
Does your port include cached access to the entire 64 megabytes of ram?
How important to users of the gp2x is the Real Time part of rtems?
Previous discussions on the case design have been limited.
Do we have any readers with the capability to build something
like this:

Any better ideas / sketches?

The Babylonions used a base 12 system. That is why we have 12 hours of daylight
/ 12 hours of night (close to the equator). The duration of an hour was variable.
And the English decided there should be 12 inches in...
What a pleasant surprise!
Might have been a BIG load of luck involved.
1. If the pins were wrong you could have fried the gp2x.
2. The USB standard indicates powering from the cable
should be limited to less than 500 milliamps current.
The gp2x has been reported to consume between
500 and 800...
When applying the Settings->System->USB Network option you must
press the 'B' key to register the setting.
The shell script that appears to be executed includes the lines:
modprobe net2272
modprobe g_file_storage file=/dev/mmcsd/disc0/disc
or

Bricks have no brains so can be neither stupid nor smart.
Users can learn to use a screwdriver and change the plug
for about a dollar. Then they could appear less dumb than
the power cord.
Depending on your need for mobility, you might also consider getting
the AC adapter. No point in using a charger to load the batteries if
you can skip the batteries.
It will also be valuable when it comes time to upgrade the firmware.
Fresh batteries or an AC adapter are recommended for that task.
Its been there for several days now:

If you use Windows 2K or Windows XP and just want a quick set-up, you can use this section to get a minimum developer system:
Two options are available:

This is okay if the file is already open but that is not possible if it
does not exist.
The ANSI C function: fp = fopen("filename", "r") will fail if the file
does not exist and set fp == NULL.
Use this to test for file existence AND accessability. Need to watch
out for ownership issues.

Here's my list, others might have different opinions:
Official SDK
Pros:
1. Uses DevC++ integrated development environment.
2. Includes linux version 1.2.25 headers and libraries.
3. Can be used for -shared or -static image creation.
4. Includes MS-Windows compiler for testing SDL code.
Cons...
