If that doesn't work the compiler probably doesn't have the necessary
support. I think the FAQ lists the minimum required compiler version -
I don't remember it off-hand.
>2. My linker don't know the option 'KEEP' within the linker script?
Then you need a newer version of the linker as well.
>3. Is there any eCos for Hitachi SH1 or SH2 available, and how can i

No. There's only support for SH3 at the moment. SH2 should be
possible to add support for, but SH1 will be a problem since there's
no g++ support for it (and as far as I know, no planned support for it
- which is a shame since I'd like to see eCos run on my brother's
LEGO MindStorm :)
Also, the SH3 support is only available in the early access program.
