各位老师好：
我在做TFFS文件系统的时候出现如下问题 ，找原因找了快两周了
希望各位能指点下：
-> tffsShow()

the baseFlashPtr is ff000000

enter the fllv160Identify

the thisVars->unlockAddr1 is ff002aa8, thisVars->unlockAddr2 is ff001550

the type is 2249

identify ok
0: socket=RFA: type=0x2249, unitSize=0x10000, mediaSize=0x200000
value = 50 = 0x32 = '2'
-> tffsDevFormat()

the baseFlashPtr is ff000000

enter the fllv160Identify

the thisVars->unlockAddr1 is ff002aa8, thisVars->unlockAddr2 is ff001550

the type is 2249

identify ok

不知道问题出在哪里了
