s3c2410 移植 U-BOOT TFTP下载TIMEOUT问题

Question

我用的蓝海微芯的S3C2410板子
用的U-BOOT是http://www.hhcn.org/maindoc/nandboot-2410-luofuchong.rar

编译好用下载到板子上U-BOOT是起来了 可用TFTP下载内核却老是TIMEOUT

IP地址配置没问题。
我在XP下用的TFTP服务器是 tftpd32 传送数据时从它的反映看 连接是没问题的 可就是不知道为什么老超时
换用 tftpdwin 软件也不行。

Answer 1

我用的 工具链是 2.95.3

PING 主机都通 难道换TFTP就不发包了 ??

Answer 2

板子PING主机
sbc2410=> ping 192.168.0.55
host 192.168.0.55 is alive  没问题
这是我的 TFTP 抓包信息

Answer 3

非常感谢 2楼的 提醒

分析抓包信息发现原来 REDHAT下防火墙没关

以前穿FTP时常碰到的 问题在这居然忘了 !!!!!
