When I halt the CPU in the infinite loop I can see that my PC is at 0x03fe88b0, if I subtract 0x3fc5000 = 0x000238b4 in flash = 0xfff238b4...according to u-boot.map this is the function serial_getc() which seems that u-boot is running and waiting for an input, and I still don't have any display on my console.
I have tried both serial ports with no results. I changed the baud rate also.
Scott: How can you write something in the serial port with the BDI it looks like you have to set many registers before sending one byte through the serial cable?
I will investigate more and let you know, I am glad that u-boot is running!
Jerry suggested you look at the TD/RD signals on an oscilloscope. Have you done this yet? Much of my life has been wasted tracing this type of stuff to incorrect terminal settings, missing null modem adaptor etc., and the o-scope can be very revealing. I don't think I'm alone here...
