LP5024: LP5024 evm board cannot control by gui control

Part Number: LP5024

I have got LP5024 evm board.

I download LP50EVM GUI (Rev. A) from

http://www.ti.com/tool/LP5024EVM#technicaldocuments

But I still cannot control the evm board.

Addr0 and Addr1 all connect to ground with jumper.

So the i2c address is 0x28.

I also check vcc and vmcu both are 5V.

The connection status indicator at the bottom left corner is green. 

But it still show can't read register.

Please help me check.
