總結(jié)的vxworks常用調(diào)試命令，學(xué)習(xí)vxworks這些東西是必須的。

1．與任務(wù)相關(guān)的命令
sp ,[arg1],...,[arg9]
－啟動任務(wù)，最多接受9個參數(shù)，默認(rèn)的優(yōu)先級100、堆棧20000字節(jié)

period n,,[arg1],...,[arg8]
－創(chuàng)建一個周期調(diào)用的任務(wù)，周期為n秒，最多接受8個參數(shù)

repeat m,,[arg1],...,[arg8]
－創(chuàng)建一個反復(fù)調(diào)用的任務(wù)，調(diào)用次數(shù)為m，m＝0時永久調(diào)用，最多也是8個參數(shù)

ts tidX         －掛起任務(wù)
tr tidX         －恢復(fù)掛起的任務(wù)
td tidX         －刪除任務(wù)
i   tidX         －顯示任務(wù)基本信息，參數(shù)為0時顯示全部任務(wù)
ti tidX         －顯示任務(wù)詳細(xì)信息，包括寄存器、堆棧等
tt tidX         －顯示任務(wù)的函數(shù)調(diào)用關(guān)系
checkStack tidX －顯示任務(wù)堆棧使用的歷史統(tǒng)計，參數(shù)為0時顯示全部任務(wù)
[其中tidX可以為任務(wù)ID 也可以為任務(wù)名]

2、系統(tǒng)信息

lkup ["string"] －在系統(tǒng)符號表中查找并列出含有"string"字符的函數(shù)及全局變量，有兩個特殊參數(shù)：
                   0，給出符號表統(tǒng)計；""（空字符串），列出全部符號

lkAddr addr      －顯示addr地址附近的符號表

l addr,[n]       －顯示addr地址開始的n條指令的反匯編，n省略時默認(rèn)為10條指令

h [n]            －n為0時列出最近執(zhí)行的shell命令，默認(rèn)20條；n非0時，設(shè)定shell記錄的歷史命令的數(shù)目

d [addr,[number],[width]]
                 －顯示addr地址開始的number個單元的內(nèi)容，width定制每個單元的寬度，可以是1、2、4、8

m addr,[width]   －按width寬度修改addr地址的內(nèi)容，width可以是1、2、4、8

memShow 1        －顯示系統(tǒng)分區(qū)上空閑和已分配空間的總數(shù)等

printErrno value －打印系統(tǒng)定義的錯誤碼的宏

3、與網(wǎng)絡(luò)相關(guān)的命令

ifShow       ["ifname"]            - show info about network interfaces
inetstatShow                       - show all Internet protocol sockets
tcpstatShow                        - show statistics for TCP
udpstatShow                        - show statistics for UDP
ipstatShow                         - show statistics for IP
icmpstatShow                       - show statistics for ICMP
arpShow                            - show a list of known ARP entries
mbufShow                           - show network stack data pool statistics
netStackSysPoolShow                - show network stack system pool statistics

routeShow                          - display all IP routes (summary information)
mRouteShow                         - display all IP routes (verbose information)
routestatShow                      - display routing statistics
routeAdd     "destaddr","gateaddr" - add route to route table
routeDelete "destaddr","gateaddr" - delete route from route table

說明：上述大多數(shù)命令都可以在help、netHelp中查到

The VxWorks shell

Useful control chars for all targets:

^S, ^Q are good for debugging

^H, ^U backspaces and delete line control

ESC to put in vi edit mode. see section 11.5 of VxWORKS programmer's manual for vi edit command summary

Shell syntax:

Can interpret "C-like" expressions. " ;" will separate command execution from the VxWORKS shell context. It is used to resolve ambiguity between commands.

Any symbol stored in the symbol table can be referenced. ex: printf, fopen, logMsg, or global variables. When calling functions, the shell ignores the "()" braces, so you may omit them.

Data Types -- strong type-casting recommended or else:

• L.H. type = R.H. type
• mixing floats and ints will result in a double
• doubles always assumed unless explicit type-casting is performed
• allocating char-strings done by:
  

  ->
-> ss = "bla bla bla"
->


• explicit address referencing: eg,
  

  ->
-> *0x1100 = 10;
->


Unlike C, Array references require an explicit application of the "&" operator. Array declarations in the shell should be avoided if at all possible.

Shell Redirection:

copy < input_file > output_file

Be careful of using "<" or ">". For example:

->
-> x > y
->


will print the value of x out to a stream named "y", while

->
-> x > y;
->


will be interpreted as "x is greater than y" !

script files can be used to spawn tasks, set variables, etc.:

->
-> < script-file
->


will invoke the commands contained within file named, script-file.

You can quickly create script files by redirecting the history listing shell command to the output and then stripping the numbers off:

->
-> h > host:/tmp/script
->

Then from the UNIX host, you do the following to strip the numbers off:

simbox%
simbox% colrm 1 5 < /tmp/script > /tmp/newscript
simbox%
