vxworks在s3c44b0x的移植快要成功,但是在连接target server时出现问题,请帮忙。
经过一段时间的努力,超级终端上终于出现了下面的输出
boot device : tsfs unit number : 0 processor number : 0 host name : host file name : /tgtsvr/vxworks flags (f) : 0x0 Booting using TSFS... Make sure that your Target Server is started with -R[oot] option. Waiting for Target Server connection... 启动target server,超级中断显示连接成功进入下面的输出: boot device : tsfs unit number : 0 processor number : 0 host name : host file name : /tgtsvr/vxworks flags (f) : 0x0 Booting using TSFS... Make sure that your Target Server is started with -R[oot] option. Waiting for Target Server connection... Done. Loading /tgtsvr/vxworks... 然后程序停在这里不动,查看target server的log显示下面的信息: tgtsvr (develop@lc): Tue Jun 15 09:06:56 2004 Checking License ...OK Connecting to target agent... succeeded. Attaching C++ interface... succeeded. Warning: No core file. Use -c option if you wish to use one. Attaching elf OMF reader for ARM CPU family... succeeded. Error: Cannot get target toolname (symbol error) Error: rpccore backend client Timed out Warning: Cannot get event. Error: rpccore backend client Timed out Warning: Cannot get event. Error: rpccore backend client Timed out Warning: Cannot get event. Error: rpccore backend client Timed out Warning: Cannot get event. 进入bootconfig.c中调试,发现,程序停在tsfsLoad()中的open(corefile,O_RDONLY,0)处,其中corefile = "/tgtsvr/vxworks"。也就是程序进入了open函数,但是并没有返回,在里面停住了。 谁能解释一下target server log中的错误信息的意思。 “Error: Cannot get target toolname (symbol error)” 看了精华栏中的文章“44box下的BSP是怎样调成的”,发现也出现上面的错误,文中是分析由于vxworks的elf格式有问题的缘故,并且其open函数是成功的。 后来我做了验证,在超级中断进入倒计时的时候,中断auto load,进入 [vxworks]的提示符命令行显示。然后我又启动target server连接,发现target server 的log出现了下面 的信息: Checking License ...OK Connecting to target agent... succeeded. Attaching C++ interface... succeeded. Warning: No core file. Use -c option if you wish to use one. Attaching elf OMF reader for ARM CPU family... succeeded. Error: Cannot get target toolname (symbol error) 可以看到这个错误信息在不load file的时候也会出现,那么是什么原因呢?至于其他的错误也许这个错误解决了,就可以了。 希望各位能帮忙给些建议和帮助。 |
