01i,24sep13,jxu fixed crc16 symbol conflict with btstack component
|
||||
01h,07may13,jxu eTFFS: added declaration of crc16() and dbgMsg
|
||||
01h,10dec12,xwu Coverity issue of tffs.
|
||||
01g,21sep10,jxu Cleanup of warning: added UNAL4_ARG_TYPE for type casting.
|
||||
01f,29jul10,pad Moved extern C statement after include statements.

01e,11dec09,zly fix defect190947: added erroe codes for TFFS
|
||||
01d,23sep09,zly make checkStatus()`s logmsg controlled.
|
||||
default no logmsg.
|
||||
01c,02feb05,aeg added include of logLib.h (SPR #106381).
|
