斑竹帮忙,刚刚下了tftpV1.6 ,不能下载uClinux
开发板加电后,d1,d3灯亮,在PC上按照user guide指示,敲入tftp -i 192.168.168.101 (PC配置IP地址为192.168.168.100),提示tftp: tftp/udp unknown service
不知道为什么?我是用sjf4510下载的tftp.bin Microsoft Windows 2000

Transfers files to and from a remote computer running the TFTP service.
TFTP [-i] host source
-i Specifies binary image transfer mode (also called
octet). In binary image mode the file is moved
literally, byte by byte. Use this mode when
transferring binary files.
host Specifies the local or remote host.
GET Transfers the file destination on the remote host to
the file source on the local host.
PUT Transfers the file source on the local host to
the file destination on the remote host.
source Specifies the file to transfer.
destination Specifies where to transfer the file.
以上是在我的 pc 上敲入 tftp 的输出,供你参考。 我在PC上敲的命令是
tftp -i 192.168.168.168.100 put image.ram
难道要分大小写么? 具体虽然不清楚,但是Linux下面基本都是区分大小写的 我用的windows操作系统,PC配置IP地址为192.168.168.100,在tftp目录中,敲入命令 tftp -i 192.168.168.101 put image.ram ,在pc上看到网卡工作正常,开发板上的d1,d3灯是亮的,就是总是提示
tftp: tftp/udp unknown service
有没有简单的方法测试网络是否通?我在PC上使用ping命令 能够ping通开发板的。 不对吧,开发板应该是 ping 不通才对,上面好像不支持 ping 的 icmp 包的。
lumit4510 上带的是交叉网线,对联板子和pc机,如果亮灯了就说明板子硬件基本没问题。 对了,你在板子上输入 load 命令没有? 在开发板上不输入load时,从PC上是无法ping通开发板的,只有在开发板上运行了load后,在给出提示后,从PC上就可以ping通开发板了,但就是tftp无法使用,总是提示tftp: tftp/udp unknown service 终于搞定了,原来是tftp客户端的问题,重新下了一个tftp的客户端,就OK了。 Microsoft Windows 2000
