Hi All,
Downloaded the latest snapshots from
http://www.ecoscentric.com/devzone/snapshots.shtml
and down loaded the latest version of the configuration tool from
http://www.ecoscentric.com/devzone/configtool.shtml
My target is Atmel EB55.
I am able to build the default configuration.
But when I try and build Redboot. I get an error due to the #error at
line 80 in
....\packages\hal\arm\arch\current\src\redboot_linux_exec.c
I was under the impression that this problem had been fixed in releases
after ecos 2.0...
see thread "Error building standard
templates" http://sourceware.org/ml/ecos-discuss/2005-05/msg00040.html
Also has anybody tried building and using the ecos when compiled with
gcc4.0.0 Particularly with regard to ARM processors?
I am aware of the need to remove the -mno-short-load-words in the gcc
options etc.
I prefer to run with the latest stable release of gcc. So wondering if
anybody has had any runtime issues.
Regards
Stewart

it's fixed in the redboot_ROM.ecm of your target so you need to either import that or
modify the ecc by hand. I don't like linux_exec being enabled by default either.

I think all I had to do is what's in the attahced patch, besides what you mention.
Most are warning fixes only those in redboot are errors IIRC.

I did not see anything particular.

Does this mean that ecos for ARM builds OK with gcc4.0 ?
