By Extended BASIC only do you mean ECB and not DECB (DriveWire HDB-DOS), 
or (D)ECB and not (Nitr)OS-9?  If the latter, what kind of problem are 
you having?  My CoCo3FPGA is the older Xilinx board, but there is a bug 
that affects me where the emulated floppy disk head isn't always at the 
position DECB expects it to be.  The upshot is that if you try the DOS 
command right away it doesn't always boot. If you then do a DIR DECB 
will 'find' the disk head.  Then you can successfully boot with the DOS 
command.  Not sure if that is a problem you're having.  Not sure if it 
affects the Altera version. But there it is.  I beat my head against 
that for a while before I found out about the bug.  Once NitrOS-9 boots, 
there is no such problem, so it must have to do with HDB-DOS' 
interaction with the Becker Port.
