Can You Use WinCE 3.0 Programs on WinCE 4.x Device?

Hi,

Like subject says, is it possible to install and run WinCE 3.0 programs on a 4.x device?

If so, what is involved?

Thanks,

Mark

Yes, absolutely. They have to either be compiled for the same CPU architecture or be Thumb code (e.g. CEF or .net Framework). They'll basically just work, with a few exceptions that will require you to provide missing dependant library files first e.g. .net Framework or the VBCE Runtime.

If you're testing things in the SCL and find that they work, please to use the compatibility reporting systems in the SCL!

Thanks....

To be clear, I don't have any WinCE devices at this time. I used to some years ago.

So, not able to do any testing now.

I was asking as I want to know IF I get a 4.x device, whether some of the older programs will install and run.

Several programs I would ideally like to use if I get a 4.x device were released many years ago as 3.0 programs.

So, I would guess that it would be highly unlikely to get a developer to re-compile their old programs as 4.x compatible programs or that they would be Thumb code.

Am I interpreting this correctly?

Thanks.

You don't need to as long as they were compiled for the same architecture. ARM for 2.10 will run on ARM CE 6.0 R3 and everything in between. SH3 for CE 1.00 will run on SH3 for CE 4.2, the same with MIPS.

THANK YOU for clarifying.....sounds good....

Just to make sure I'm making correct assumptions...

Would programs that run on an ARM SA-1110 device also run on an XScale PXA255 device?

Think the XScale PXA255 chip is an Intel ARM chip....

Thanks.

Yeah, a lot of folks playing with ARM CE 6 devices found a lot of ARM CE 3 programs handy when they couldn't find many ARM CE 6 programs. And as I mentioned in another thread, I have two MIPS CE 5 devices that can run MIPS apps all the way back to CE 1.

As for StrongARM apps running on X-Scale devices, yes, in general they will work. (Yes, the PXA-2XX was built on ARM architecture.) But the other way around, no. cmonex had a converter that changed the processor ID on apps from C2 01 (thumb) to C0 01 (standard ARM), and some of these programs would then work in SA-1110 devices.

Thanks for the info!

Got it now....
