IWR1843BOOST: Uart pin connection to 20-pin connector

Hi Brennan, 

Thanks for your quick reply.

Since, IWR1843 doesn't provide switch control, I am using IWR6843 with ICBOOST now for easy debugging in initial phase. 

S1 switch positions are set as given in Table 2-1. Switch Settings (Position for 40-Pin LP/BP) of document 60GHz mmWave Sensor EVMs (Rev. D) (ti.com) to enable 40 pin connectors (J5/J6). On doing so, I am able to get data of 'Auxiliary Data Port' through MSS logger pin (J6.9) by simply connecting the TTL to USB connector's RX pin on the J6.9.

But, following the same setting, I am not getting data on J5.7/J5.5. I am expecting that switch S1.5 in off position routes 'Application/user UART COM port' data to 40pin connector (RS232 connections J5.7 and J5.5).

I want to get the 'Application/user UART COM port' data through J5 connections and then transmit it wirelessly. 

Thanks & Regards, 

Radha

Hi Brennan, 

Thank you so much for the link.

What setting should I keep to get the 5V output from 40-pin LP/BP? Keeping the settings mentioned at the bottom of link doesn't enable 5V output pin J5.2.

Thanks & Regards,
