[ECOS] No eCos for ColdFire?

[ECOS] No eCos for ColdFire?

[James Dabbs]

It would seem that ColdFire would be a natural target for eCos.  Are there
plans for any to support ColdFire?

the TCP/IP thing is in IMO, surely possible. Perhaps one way is to
look at the Linux virtual ethernet device TAP (part of the VTUN project).
