Hi,

     Thanks for the reply. Trust me I did as well check on that and have
both the baud rates set up at 57,600.I will dwell more into the register
configuration part and get back to you with precise register values and
signal logic levels.I may get some more hints from you.

You can actually check the baud rate set in the hardware, in the
configuration tool & in the serial port settings, the baud rate in all the
cases should be same..

Hi,

     I am new to the OS(Linux) world. I am a basically Hardware Design
Engineer. At this stage I have a custom hardware with a SH7750 processor,
Intel Flash, SDRAM, FPGA etc..I am trying to intially develop a RedBoot
loader for that board. I am using the ecos config tool running on a linux
workstation to do this. I am at the point now where I have a image developed
from one of the board packages close to my board, customorized and loaded
into the flash. I see all the chip select signals going to the flash,
Address and Data signals, Clock signals etc. I am sure that the processor is
communicating with the flash. I am not seeing any output at my Serial port
which uses SCIF port of SH7750. The host I am connecting the serial cable is
windows based. what could be wrong? 

Thanks,        
Raghu
