This problem occurs when I click “Start/Stop communication” button in FreeMaster，after I’ve debugged&downloaded the programs to KE02.

Wondering how to sovle this，thx！

Hi,

This means a communication error has occurred, the command's checksum value was invalid. When KE02 freemaster code receive an error command,  it will notify host computer. There is a error code FMSTR_STC_CMDCSERR in freemaster_protocol.h. You can monitor it in debug.
