I am using Custom IBM PowerPC 440GX Board.After Dumping the BIN file It is not Display any thing in TeraTerm Mainly i am refereed Ocotea Board. ocotea.c file i am not initialized FPGA because in board we are not using.(Com1 port address also i am changed #define CONFIG_SYS_NS16550_COM1 (CONFIG_SYS_PERIPHERAL_UART0_BASE) (#define CONFIG_SYS_PERIPHERAL_UART0_BASE 0xa1080000) -->Ocotea.c file Details int board_early_init_f (void) { unsigned long mfr; unsigned char *UartPtr; int i; UartPtr = (unsigned char *)(0xA1080000); /* Basically i am sending one character to UART*/ *(UartPtr + 3) = 0x83; for(i=0;i<100000;i++); *(UartPtr + 0) = 0x1b; for(i=0;i<100000;i++); *(UartPtr + 1) = 0x00; for(i=0;i<100000;i++); *(UartPtr + 3) = 0x03; for(i=0;i<100000;i++); *(UartPtr + 0) = 0x41;
