[ECOS] Problem using SMC1 on 860 platform

[ECOS] Problem using SMC1 on 860 platform

[Rick Davis]

I am trying to use SMC1 for both the diagnostic port and the stdio port.
Right now Redboot works fine. When I build an eCos app just using SMC1 as
the diagnostic port and I DO NOT enable the SMC1 hardware driver, my
application boots. If I enable the SMC1 hardware driver, the app hangs up
just after the eCos startup initialization code initializes /dev/ser1, which
is SMC1.

Any help would be appreciated.

This is a known problem (BUG #90391).  I've just spent about 15 hours(!)
looking for it, to no avail.  For now, the only thing I can say is don't
enable the SMC1 driver.

Sorry.

I've just checked in a patch which fixes this for me.  Please let 
me know if you still have problems.
