eboot中CS8900初始化问题

[LouisScola]

Reset(void)
{
	BOOL r = FALSE;
	USHORT dummy;
	int i;
											/* Set RESET bit of SelfCTL register.	*/
	do 
	{
		//WRITE_REG1(PKTPG_SELF_CTL, SELF_CTL_RESET | SELF_CTL_LOW_BITS);
		WRITE_REG1(PKTPG_SELF_CTL, SELF_CTL_RESET);

								/* Wait until INITD bit of SelfST register is set.	*/
		for (i = 0; i < MAX_COUNT; i++)
		{
			dummy = READ_REG1(PKTPG_SELF_ST);
			if (dummy & SELF_ST_INITD) break;
		}

		if (i >= MAX_COUNT)
		{
			RETAILMSG(1, (TEXT("ERROR: Reset: Reset failed (SelfST).\r\n")));
			break;
		}

						/* Wait until SIBUSY bit of SelfST register is cleared.		*/
		for (i = 0; i < MAX_COUNT; i++)
		{
			dummy = READ_REG1(PKTPG_SELF_ST);
			if ((dummy & SELF_ST_SIBUSY) == 0) break;
		}

		if (i >= MAX_COUNT)
		{
			RETAILMSG(1, (TEXT("ERROR: Reset: Reset failed (SIBUSY).\r\n")));
			break;
		}
		r = TRUE;

	} while (0);

在eboot中CS8900初始化的时候在这里就不能初始化了，硬件只使用了I/O模式，我已经把Memory模式注释了，但在执行到这里复位Reset（ ）的时候，报错，请问是什么错误？

打印信息就是ERROR: Reset: Reset failed (SelfST)

还是没解决，求高人！！！！！！！

纠结了几天终于解决，就是CS8900的时序问题，我把2440的主频配成了400MHz，主频太高了，8900时序错误，配成主频266M就成功初始化了，希望对后来人有用
