<P><FONT SIZE=2>Hi Grant&Wolfgang<BR>
<BR>
thanks for yours posts. You are right about WR. For lite5200 only few patchs have been used. Most of the job is for support other boards or to introduce some patchs for its debug system.<BR>
<BR>
The main HW difference between our board and lite5200 is:<BR>
console on PSC3 and<BR>
<BR>
port_config. On lite5200 defined as<BR>
<BR>
/* Set port config */<BR>
port_config = in_be32(&gpio->port_config);<BR>
<BR>
port_config &= ~0x00800000; /* 48Mhz internal, pin is GPIO */<BR>
<BR>
port_config &= ~0x00007000; /* USB port : Differential mode */<BR>
port_config |= 0x00001000; /* USB 1 only */<BR>
<BR>
port_config &= ~0x03000000; /* ATA CS is on csb_4/5 */<BR>
port_config |= 0x01000000;<BR>
<BR>
on our HW defined as:<BR>
/* Radionav configuration */<BR>
port_config = 0x0C712E66;<BR>
<BR>
I still do not understand our bug with USB.<BR>
Have you got some suggestions or some test to be performed in order to find out a solutions?<BR>
<BR>
Thanks J<BR>

Check your settings in the port config register.<BR>
