init.c

arm开发很好的例程

#include "bios.h"
#include "uart.h"


void Device_init(void)
{
	//-----------------Init_EBIU--------------------
	
	*pEBIU_AMBCTL0	= 0x7bb07bb0;	// <--|Write access time = 7 cycles, read access time = 11 cycles, no ARDY
	*pEBIU_AMBCTL1	= 0x7bb07bb0;	//    |Hold time = 2 cycles, setup time = 3 cycles, transition time = 4 cycles
	*pEBIU_AMGCTL	= 0x000F;		//	  |Enable all memory banks

	
	//----------------Init UART -------------------
	uart_init();
