Hi team,

I tried to power on LP5024 EVM board but not sure why I could not write/read device register.

Could you advise how to fix it?

I didn't change any EVM board jumpers and provide 5V power in VIN_EXT and GND.

Thanks

Hi Paul,

You can first refer to the following thread.

Please provide a picture concerning about your EVM setup so I can confirm the jumper position.

Charles,

Below is my EVM board jumper setup for your reference.

Now my I2C interface is enable but can't control EVM board LED.

Is there any procedure wrong?

Thanks

Hi Paul,

The hardware setup seems to be OK.

What do you mean by "Now my I2C interface is enable but can't control EVM board LED"?

Can you write the register now?
