I downloaded eCos from CVS and cvs updated to tag ecos-v3_0-branch. 
Since my build system relies on command-line ecosconfig, I then 
configured and built the host tools (in a separate directory) from 
~ECOS/host/ without problems.

My eCos setup (one of the two) is the BlackFin port from the Univ 
Chemnitz, extended by me to other BlackFin CPUs and DevKits. I copied 
all BlackFin-related packages into the 3.0 tree, and my beta NAND flash 
and YAFFS packages. I compiled and built for EZ-Kit BF548 which includes 
 YAFFS/NAND. I ran into exactly one problem: YAFFS requires chmod(), so 
I diff/patched that from my usual eCos checkout into eCos 3.0, see 
attached patch.

Then I built and ran the fileio1 test for YAFFS2. All went without problems.

Then I built the libs for my application, RFID Guardian 
(http://www.rfidguardian.org). I built the file system traversal 
executable for it, which uses threads, interrupt-driven serial port, and 
all kinds of file IO. All went well.

This obviously isn't an exhaustive test, but it shows that threads, 
serial port interrupts, my newer packages etc work well without any 
adaptation (except addition of chmod()).
