[ECOS] eCos on STR9 ?

[Christian Jaeger <christian at jaeger dot mine dot nu>]

Hello,

My interest is in running an OS on STR9 (STR9xFA, STR911/STR912). There 
is no mention of these chips whatsoever in the CVS sources, and the only 
information regarding running eCos on the STR9 has been the following 
posts by a few people interested in this, but it seems there has still 
nothing come out of this.

(http://sourceware.org/ml/ecos-devel/2006-06/msg00017.html or better: )
http://www.mail-archive.com/ecos-devel@ecos.sourceware.org/msg00160.html

and:

I don't currently have more than maybe a day of time to invest into 
gettting eCos to run on the STR9, otherwise I'll go with another OS (for 
now, anyway). I don't need ethernet functionality, only SPI and some 
manually toggled I/O as well as PWM and variable frequency pulse output 
(I guess I'd do the latter things myself anyway; btw if possible I'd 
like to use all four timers for my application, although one of them 
could run at a constant frequency and so could probably also be used to 
generate ticks) and the usual reset and memory/irq routine setup stuff; 
how difficult would it be to get that much of eCos to run? I don't have 
previous programming experience with the STR9 nor with eCos.

Christian.
