This happens because no serial devices are enabled.
There are 4 esci devices/channels:
CYGPKG_IO_SERIAL_FREESCALE_ESCI_A (/dev/ser0)
CYGPKG_IO_SERIAL_FREESCALE_ESCI_B (/dev/ser1)
CYGPKG_IO_SERIAL_FREESCALE_ESCI_C (/dev/ser2)
CYGPKG_IO_SERIAL_FREESCALE_ESCI_D (/dev/ser3)

I didn't notice this behavior because I have always enabled some of them.
It is possible to make one of them enabled by default in
ser_freescale_esci.cdl but I think that it's user prerogative.
