查看这条指令时干什么的
把vxworks反汇编
第一种方法：l 0x00258094
第二种方法：
点vxworks就可以看
怎么查看vxworks 引导到内存的位置？你的RAM从什么地址开始？
makefile 里面
ROM_TEXT_ADRS = fff00100 # ROM entry address
ROM_SIZE = 00100000 # number of bytes of ROM space
ROM_WARM_ADRS = fff00108 # ROM warm entry address
ROM_LINK_ADRS = fff00000
RAM_LOW_ADRS = 00100000 # RAM text/data address
RAM_HIGH_ADRS = 01000000 # RAM text/data address
任务堆栈大小？
10000
log任务有五个
tNetCheck
tNet1Recv
tNet1Send
taskdatgen
taskIdle
建议RAM_LOW_ADRS = 00100000 # RAM text/data address 改成200000
makefile里面和config.h里面都改
