Hello ,
I am reviewing circuit diagram of IWR6843ISK-ODS by below document;
PROC075A(001)_Sch.pdf
iwr6843.pd.pdf
Let me make below questions ;
A) RADAR_RS232RX/TX
Those lines are used for UART communication for debugging. Are they utilized by demo like people counting or out of box ?
B) RADAR_TMS/TCK/TDI/TDO_SOP0
Those lines are used for JTAG communication for debugging. Are they utilized by demo like people counting or out of box ?
C) RADAR_DP0/1/2/3/4/5/6/7
I am not sure purpose of those lines. Probably debug interface or debug trace output but could you clarify those purpose ? Are they utilized by demo like people counting or out of box ?
D) RADAR_SDA/SCL
According to datasheet, it can be used for PMIC control. But are they utilized by demo like people counting or out of box ?
Best regads,

Hi,
Takatoshi Tsuji said:A) RADAR_RS232RX/TX
yes, the RX and TX are used by the user COM port for flashing and sending config files. MSS_logger pin is used for the data COM port.
Takatoshi Tsuji said:B) RADAR_TMS/TCK/TDI/TDO_SOP0
These pins are required for JTAG and Debugging
Takatoshi Tsuji said:C) RADAR_DP0/1/2/3/4/5/6/7
These are not used by the demo.
Takatoshi Tsuji said:D) RADAR_SDA/SCL
the OOB does not utilize this, but it can be used to interface with other peripherals.

Hello Charles,
Please kindly explain JTAG communication in details. I would ike to know what type debugging is proceeded through this line so that I will remove unnecessary interfance on our original antenna board design.
(According to wiki, JTAG is normally used for verifying design of circuit board.... https://en.wikipedia.org/wiki/JTAG)

Hello Charles,
I understand JTAG purpose. BTW, I suppose SPI (to external MCU) is rarely used in case of IWR6843, because there is embedded MCU. Am I right ?

Hi,
It all depends on your application. The interfaces and peripherals needed depends on your use case

Hello Charles,
Excuse me for my bad query in previous mail. Could you kindly let me know SPI interfance of IWR6843ISK is used for playing indoor_false_detection demo and Out_of_box demo ?
Best regards,

Hello Charles,
Could you kindly make sure if DP0/1/2/3/4/5/6/7, RADAR_SDA/SCL and SPI interface are used with capture board(DCA1000EVM through MMWAVEICBOOST) ?
Best regards,
Taka
Hello Charles,
Yes, I checked already the schematic diagram but I guess some of connections may be prepared as backup for future use and are not used currently.
I would like to know whether DPx, RADAR_SDA/SCL and SPI interface are used or not.
Best regards,
Taka
