Unfortunately, an usb connected cdrom is unusable on a Yeelong (so the
filesystem.squashfs, boot.cfg etc., which I downloaded are quite
useless).
While the devls command, executed on a Yeelong at the PMON prompt didnt
return awaited info about usb cdrom I connected to it, it would require
to update the pmon version installed (as the sources in
git://dev.lemote.com/pmon.git include the support of the iso9660
filesystem).
However, to be on the safe side, this would require to be able to
reprogramm the PLCC chip, where the pmon resides, in the event of a
failed flashing.
