AWR1843BOOST: Radar is in warm reset and doesn't respond

Manoj Wakdikar

Part Number: AWR1843BOOST

Hi,

I am using AWR1843BOOST module, till now i was able to work fine on board, but now on power on of device i see WARM RESET LED glowing and module is unable to response.

I have gone through below thread,

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1031605/awr1843boost-warm-reset

Could you please help me to understand that where I can probe to see input and output voltages of PMIC.

Thanks,
Manoj

Hi,

Have you made any changes to the board?

Our team has never seen issues with the BOOST EVM.

Please find the schematics of the board on the EVM page

Hi Cesar,

I have connected 0 ohm resistors to get the data on header connector. I wanted to capture radar data by interfacing it with another microcontroller over UART.

I was able to get the data on MSS_LOGGER pin successfully also able to collect this data on another microcontroller's UART, but now I it is not responding and making warm reset led ON.

Thanks,

Manoj

Yes, please check the schematics to debug your board.

There is definitely something in hw that is no longer working properly

thank you
