Part Number: DS80PCI800

Hi TI experts,

I have one DS80PCI800 showing weird register read/write in SMBUS slave mode. As picture shows, there're four channel are constant "detected" even there's no connection from input/output.

And when I try to read low level register, it's constant 0, as video shows. what's the problem ?

Hi Xia,

It seems GUI is not communicating with the DS80PCI800 device.

1). Is it possible that we might be running in demo mode?

2). Please check USB connection to make sure win10 sees the DS80PCI800 USB port.

Regards,, Nasser
