Does SCC1 work correctly in U-Boot ? If not, you should fix that first. I'll assume it does. There are many issues which could lead to a silent serial console. The serial port could be misconfigured, or the kernel could crash for another reason before the serial port is initialized. Have you been able to get a serial console on another serial port (SMC) ? Are the clock frequencies computed by U-Boot and passed to the Linux kernel correct ? Do you have a hardware debugger (BDI2000) that you can connect to the processor to see if Linux crashes before initializing the serial port ? If not, you will probably have to take a try at led-debugging (make some leds blink at various point in the Linux kernel to try to find out what happens), but that's really no fun. Laurent Pinchart
