MMWAVEICBOOST: How to use external XDS emulators instead of onboard XDS110

Part Number: MMWAVEICBOOST
Other Parts Discussed in Thread: IWR6843AOPEVM, , UNIFLASH, IWR6843AOP

Dear support team,

I am using IWR6843AOPEVM + MMWAVEICBOOST to debug demo. I've used MMWAVEICBOOST onboard XDS110 to debug IWR6843AOPEVM, it worked well. Now I'm trying to use external XDS emulators connecting with J19 to debug. Refering the document 'mmWaveICBoost and Antenna Module_UserGuide', it says 'This connector provides a JTAG interface shown in Figure 21 for debug and development through external XDS emulators. To use this interface, the JTAG lines to the onboard emulator (XDS110) must be disconnected and this is done with S1 (12th position of DIP switch should be open) and external emulator on MIPI 60-pin connector also to be disconnected '. I've tried to switch S1.12  and S1.5 to off, but it didn't work! Is there any thing else I missed? Did I misunderstand?

Regards,

Benson

    Hi Jitendra,

    I have installed XDS110 driver for my external XDS 110 emulator and can find two XDS110 com ports, two TI XDS110 debug probes.

    I want to know:

    Q1: How could I use this external XDS emulator(Connecting with J19 14-pin JTAG) to flash prebuild bin files by 'UniFlash' ?

    Q2: When I run 'mmWave_Demo_Visualizer_IWR6843AOP 1.0.0'. How could I send commands and get user data through two com ports of external XDS 110?

    Q3: For Q1 and Q2, should I change any jumpers or switches on MMWAVEICBOOST board?  

    Regards,

    Benson

    Benson,

     Q1 & Q2   Naively, external emulators are used for JTAG purpose only, from this interface one could connect to device cores (ARM core and DSP cores).

    For Flashing purpose one need to connect RS232_TX and RS232_RX pins need to be connected to corresponding UART ports in external emulator. 

    Apart from that processed data from the mmWave sensor would be sent out on MSS_logger (Single wire UART Tx  from the sensor) This need to go to UART RX pin of the external emulator UART interface. 

     User UART from which commands are sent in to the sensor  and data UART from which processed data would be sent out. 

    Q3: By default on board JTAG lines are connected to XDS110 device,

    If you want to connect JTAG through external 14 Pin connector S12 switch on the mux need to be changed. 

     

    However this only routes the JTAG signals, Not the RS232_TX/RX and MSS_Logger signals. This need to be incorporated separately.

    Thanks and regards,
