AWR1843BOOST: Out of box demo - use UART ports

KACZUB

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1642, AWR1642BOOST, AWR1843

Hello,

In my design I would like to interface with the AWR1843BOOST using a microcontroller instead of a PC. I was trying to obtain the results through the onboard pins, however I didn't succeed. I found here that pin 9 on J5 Connector should be MSS LOGGER, but it doesn't output anything. Is it possible to modify the demo somehow, so it would be possible to both send the configuration to the device and obtain the detection data using only hardware UART pins?

I am using Out of box demo from SDK 3.03.

Thank you,

Hi KZ,

On AWR1642BOOST, J5:9 MSS_LOGGER is not connected, for that, you need to solder 0ohm resistor on R26. Please refer AWR1642 schematic and assembly file to locate this resistor on the board.

Thank you very much Jitendra for the quick reply, however my question refers to AWR1843, not AWR1642. Is it also not connected on my board and should I place the resistor on the same spot?

Hello Kacper,

Yes, even for AWR1843BOOST the resister needs to be assembled.

You can refer to the schematics and assembly files at the following page http://www.ti.com/tool/AWR1843BOOST

Thank you very much.

My last question is if it is possible to access also the UART port used for configuration purpose, via one of the available pins? In the demo it is called CFG_port. I am wondering if it is maybe connected to the RS232 TX and RX, so I would have to solder R166 and R169 or am I wrong?

Hello Kacper,

Yes, you are right. You can access the configuration port from the J6 connector by assembling R166 and R169. But you also need to disconnect these lines from the onboard XDS110 emulator by removing R128, R129.

Vivek
