Re: any SDK for build binaries on ARM5 platform?

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Thank you Chris! The URL you provided is very informative! I have a further
concern after reading the material. Suppose I build an application using ARM
v4 tool chain for Win CE, and then I use ARMv5te device to run the program,
will it be ok? I have some concerns about whether ARMv5te CPU will
mis-interprete some ARM v4 instructions by the new ARMv5te interpreter. And I
have not found any official announcement from the URL you sent, which means
ARMv5te is 100% (fully) compatible with ARM v4 binaries.

BTW: you mentioned in your reply, there is a Microsoft platform building
newsgroup. I think it must be referred. Could you kindly point the URL please?

v5TE simply added a few THUMB instructions and DSP stuff. No versions of CE
use as none of Microsoft's compilers support it, therefore even if you're
using a v5TE capable chip, you are not using the v5TE features. The fact
that the OS was compiled for v4 or v4I and is running proves that they are
compatible. Even if you could compile your app to use the v5TE stuff (can
be done if you use the ARM toolchain I believe), the gains would be
marginal, as every OS call you make still uses only the v4 instructions.

More on ARM is here:
http://www.arm.com/products/CPUs/architecture.html

And I'm sure there's more info relating directly to CE in the platfbuilder
newsgroup archive, especially aroung the time the 270 came out, as this was
asked a lot back then.

Thanks Chris, do you have any official documents to show ARM v5 and ARM v4
is
100% compatible?

It's a WM 5.0 device so use the WM 5.0 SDK. There are no CE SDKs that
take
advantage of specific ARMv5 features as there are no CE versions that do.
ARMv5 is a superset of v4, so yes, they are compatible.

Hello everyone,


I am using Visual Studio 2005, and I want to build some binaries for a
new
Pocket PC (Windows Mobile 2005, ARM V5te). This device is really cool,
which
is Intel PXA27x series!

But, I can not find SDK used in Visual Studio 2005 to build binaries --
only
for ARM4 series.

So, I am wondering the two questions,

1. whether there are any SDK for Visual Studio 2005 to make build for
ARM
5
platform?

2. whether ARM 4 is 100% compatible with ARM 5 (if it is, I could use
existing Windows Mobile 2005 SDK's ARM 4 toolchain to make the build
and
run
on ARM 5).


thanks in advance,
George
