hello, We have developed a custom board for network application. Its serial communication port is SCC1 and has same design as ADS board (pins). Only difference is custom board is running at cpu-266Mhz, cpm-166Mhz, bus-66Mhz.
Problem: Serial port is not printing any character on the hyperterminal. I used CRO to see any activity on the transmit pin (TXD pin) but there is nothing happening. Control will enter the serial_init function called from cpu_init_f function. So i checked my SCC1 parallel port pin configuration by writing a piece of code which will dump the registers value to DPRAM starting addresses. It is being set properly. Then i also checked the processor configuation parameter. Everything is supposed to be OK with exact core, cpm and bus frequency calculated. Iam using BDI2000 emulator just to load the ppcboot code and see the dump. Can u please suggest possible place where something might have gone wrong? with rgds, kamal ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
