EV2300 Firmware Update

I have an EV2300 kit (HPA002) and this Version is 3.1c. How to update the firmware to 3.1m?

I use this kit for bq2084(SMbus) and work fine. Now I want to use this kit to program bq2022a(HDQ), but it alyays show  "No device detect ". I use another kit from my friend (version 3.1m) and can work well, so I think my kit too old...

Please provide a tool to update the firmware, thanks!

Thanks for the help,

Larry
