Allann, Hmm, yes. In addition, these lines looks suspect:
> val32 = in_be32(&gpio->port_config); > val32 &= ~0x700; > val32 |= 0x600; > out_be32(&gpio->port_config, val32); I don't have the register's header file in front of me, but I'm pretty sure this refers to MBAR+0xb00. If that's the case, you seem to be configuring the port to be in CODEC mode and not UART mode. Try this instead: val32 = in_be32(&gpio->port_config); val32 &= ~0xf00; val32 |= 0x400; out_be32(&gpio->port_config, val32); You may want to refer to the MPC5200 manual. Page 15-43 has a nice sequence you can go through to configure a port to be a UART. Open Systems International, Inc.
