各位大哥,
最近我做了一个BSP,自己加了串口、时钟、中断。想用WDB下载VxWorks(单串口),在启动Target Server的时候遇到了问题,我听说要启动WDB,就必须用wdbSuSpendSystemHere(NULL,0)把系统挂起来,我试了一下,tgtsrv还真的连上了,但是tgtsvr显示:
tgtsvr (username@yuyinan): Fri Sep 09 20:31:26 2005
Checking License ...OK
Connecting to target agent... succeeded.
Attaching C++ interface... succeeded.
Attaching elf OMF reader for ARM CPU family... succeeded.
Warning: Target checksum: 0x39cf (computed from 0x1000 to 0x76a40).
Host checksum: 0xd2d1 (computed from 0x10c0080 to 0x1135ac0).
Warning: Core file checksums do not match.
Error: rpccore backend client Procedure unavailable
Error: Cannot get target toolname (gopher Error)
然后VIO就打开了,但上面没显示,往里输入就说:
Warning: Cannot write to virtual I/O channel 0
请问这是怎么回事?到底VxWorks开始下载了没有,不会是我的串口驱动有什么问题吧?请各位大哥一定不吝赐教,多谢多谢!
