IWR6843ISK-ODS: IWR6843ISK-ODS failed to run the demo , status =0x1e

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: UNIFLASH,

I have this dev kit , however I got the same error with this page https://e2e.ti.com/support/sensors/f/1023/t/755164?MMWAVEICBOOST-MMWave-Demo-Visualizer-Init-Calibration-Status-0x1e

Because this thread was locked , I ask again here.

PC: Windows 10 , with mmWave, Uniflash , Visualizer + plugin  ...

Dev board connect to PC via USB on XDS110 ports , 2 COM ports seen as normally. Power is 5v/5A max , jumper SOP2 is open for demo. Dev board is not re-flashed. logs show correct PN + version 3.0

It seem Main UART was OK , showed Connected. But Aux Uart showed : waiting for data alway

When I press send config , It show 

"mmwDemo:/>sensorStart
Debug: Init Calibration Status = 0x1e

Exception: main.c, line 981.

"

and connection is still single Port connected.

Switch to Plot tab , I couldn't see anything.

My power supply is 5v , 5A max.
