Re: [ECOS] arm-elf-gcc

[GREGHOL]

I have gcc-elf-gcc tools for 3.0.2 and 2.95.3 for 
cygwin (win98) and linux. I guess I can manage to put 
it somewhere.

  Marcelo, we have a recent precompiled GNU arm-elf distribution with the 
most useful features enabled at http://www.ariusdsp.com/gnuarm/. Perhaps 
you can try that.

  Add it to the windows PATH environment variable, or run "export 
PATH="[toolchain-bin-dir]:$PATH" in a shell, where [toolchain-bin-dir] is 
the bin directory of your toolchain.

  Regards.

[ECOS] arm-elf-gcc

[Marcelo]

We are using an ATMEL AT91EB40A. We want to compile, debug, download file
image via serial (Angel) and via JTAG to FLASH or RAM.

Our host computer runs Win98.
So I installed Cygwin (Setup.exe, install from internet, etc....) and Ecos
1.3.1 from
ftp://sources.redhat.com/pub/ecos/releases/ecos-1.3.1/eCos131.exe.

After that I downloaded, decompressed, Configured, Installed and built
binutils, GCC and Insight, according with:
http://ecos.sourceware.org/tools/win-arm-elf.html.

I Didn't understand this: This directory should be added to the head of your
PATH. The eCos Configuration Tool also allows you to set the build tools
path.

So I ignored this part and started to use ecos configuration tool.

I followed the steps from: "Configuring and Building eCos from Source" but
at the Build dialog it asks me the arm-elf-gcc path. And I can't find this
file on my computer.

Did I forget any tool installation?

Please help me!

Marcelo Kenji

eCos 1.3.1 is very old. Too old. Try again with 2.0. Follow the
instructions at http://ecos.sourceware.org.

[ECOS] arm-elf-gcc

[Mike A]

Hi,

Is arm-elf-gcc prebuilt tool chain for windows available on the net? If so 
please let me know the URL.

Thanks,
-Mike.

I STRONGLY recommend that you build from source but you can probably
use the XScale development tools since XScale is an ARM compatible
chip.  You can get those from Intel.

http://www.intel.com/design/intelxscale/dev_tools/010827/

I'll build you the development tools for $200 ;)

You'll find out eventually that the gcc compiler for arm is crap, but
eCos is dependant on the g++ toolchain.   Arcc is at least twice
as fast as gcc is in terms of optimized code it produces.

I don't know if that toolchain will work reliably for non-xscale
cores. It will generate code that uses 64-bit loads and stores
and other insns that a lot of ARM cores can't handle. But a
-mcpu= flag may be sufficient to get around that particular issue.
