J. Day" Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: I think this is due to the config file just not getting updated. The driver for the uart on CPM1 (8xx) and CPM2 (82xx/85xx) is the same code. It started as a driver for only CPM2 and thus the config options reference CPM2. Will make a note to cleanup the config file for the driver - kumar On Jul 8, 2004, at 3:53 PM, Robert P. J.
