IWR1443BOOST: Unused pin P7 of IWR1443

Hi Feng,

The recommendation is to add pullup resistor to prevent the pin from floating at any point.

My question is if we missed that pull up resistor, what could happen, the IWR1443 totally do not work or something else?

Feng,

I won't expect the boards to fail because the pin is left floating. It can however result in false data on the line.

do you have a IWR1443 that isn't working?

We do not use NERR_IN data, what other data could be false data? We are building IWR1443 board, the assembly not finish yet

Hi,

You can remove the pullups on the Booster pack and run your application to see if there is any adverse effect. I would expect the board to work just fine if the pin is not used.
