wifi网卡驱动在开发板上 ifconfig ra0 up 异常

secureCRT上面跑arm9的板子，在secureCRT上敲 ifconfig ra0 up 命令(开启网卡)，然后就报下面错误  
SIOCSIFFLAGS: Operation not permitted
然后我再敲 dmesg 显示开机信息，接下来是我找到具体错误的信息
<-- RTMPAllocTxRxRingMemory, Status=0
<-- RTMPAllocAdapterBlock, Status=0
usbcore: registered new interface driver rt2870
(Efuse for 3062/3562/3572) Size=0x2d [2d0-2fc]
NICLoadFirmware: MCU is not ready
ERROR!!! NICLoadFirmware failed, Status[=0x00000001]
!!! rt28xx Initialized fail !!!

请高手们指点迷津？

我自己先顶下，高手们哪里去了啊.....
