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.

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)

Best regards,

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 ?

Best regards,

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,

Taka

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
