Hi,you all,

 

After successfully porting on LITE_DW,I tried my best to make my design board work.But no good serial output by now.At first,there were some characters displayed on the screen in a state disorder with help of BDI2000 and GDB.I,HOWEVER,cannot see them after making some changes on hardware and software.For no CPLD on my board,there is no hardware handshake circuit.Does it matter?

 

My MPC8xx connects the RS232 transcerer chip as following:

1.SMC1

 

MPC823E                             MAX3225

PB24-SMC1TXD    --------------     T1IN

PB25-SMC1RXD   --------------      R1OUT

PB22-EN              -------------       FOFF
