沉寂几个月的心血,终于告一段落,终于可以愉快地上网玩了,将来还请各位大大多多指导!

总结一下成果:

           使用了廉价ARM7芯片S3C44B0X和RTL8019网络芯片,没办法,成本控制啊!

           编写了BootLoader,写了uClinux的控制台驱动,移植成功网卡驱动,Yeah!

下一步工作:

           准备启动Telnet服务程序,去掉串口Console,就可以使用两个串口了。

Look:

----------------------------------------------------------
Program    :    DuTao''s 44b0x BootLoader Ver 0.60
UART config:    115.2kbps,8Bit,NP,UART0
Flash ID   :    0x236d00bf
RTL8019 ID :    0x00007050
Initializing system... ...
----------------------------------------------------------
1.Download code to SDRAM.
2.Copy data in SDRAM.
3.Run at specify address.
4.Start uClinux.
5.View Data.
6.Programe Flash.
