AWR2944: AWR2944 Debugging via TM4C1294NCPDTT3 microcontroller

Part Number: AWR2944

Hello all,

I've two confusion last days about AWR2944 radar evaluation module.

Q1 : wonder how to debug AWR2944 IC by not using TM4C1294NCPDTT3 that located on evaluation module. Let's image that we are in volume production, hence, we wouldn't like to use TM4C1294NCPDTT3 microcontroller in every produced radars. Is there any way to debug AWR2944 IC by using external device or do we need to develop a debug card that can debug the AWR2944 ? İf there is a external debugger that has been currently selling by TI, this will be better soution for me. Is there any solution for it ? By the way, would XDS110 debug probe module be appropriate for debugging on AWR2944 ?

Q2 : When i had been reviewing the schematic and layout designs of the AWR2944 evaluation module, the TM4C1294NCPDTT3 microcontroller was used in evaluation module just for 2 reason. First one is debug and second one is data acquisition. Am i right ?

    Hello,

    1. Yes, the external XDS110 debug probe is a suitable replacement for the onboard MCU for JTAG access. Most customers would just put a JTAG header on their board and use the XDS110 debug probe on their production sensor.

    2. The XDS110 MCU is used for two reasons: 1. JTAG debugging; 2. UART data input/output

    JTAG can be accessed using an external XDS110 debug probe as mentioned. To access the UART, you can also bring the UART to a header and then use an external USB to UART converter like below.
