AWR1443BOOST: AWR1443 EVM LED DS1 is always on in dev mode.

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443, , AWR1243

Hi,

Q1: I have an AWR1443BOOST ES2.0, which works properly in Flash programming mode(101) and Functional mode(001) . The power supply is 5V 1A. But the LED DS1 is on when it works in Dev mode(011).  I have changed another PC but  DS1 is still on.  I can't find the problem. Are there any necessary steps skipped by me before the AWR1443 EVM turned into Dev mode? Or the power supply doesn't meet the requirement? (ps: it works properly in the other two modes with the same 5V 1A power supply.)

Q2: The Q1 happens when the AWR1443 EVM is not connected with  DCA1000 EVM. Then I guess it might be necessary to connect AWR1443 EVM with DCA1000 EVM when in Dev mode.So I connected the DCA1000 EVM with the AWR1443 EVM as the user's guide shown. The situation is complex. Please be patient.

①The DCA1000 EVM gets power from a 60-pin high density connector of AWR1443 EVM, when the power selection switch is closed to position 3.The AWR1443 EVM is powered by 5V 1A power. The LED DS1 is on. The PC cannot detect the four COM ports of  DCA1000 EVM. And the 5V-LED on the DCA1000 EVM is off.

②The DCA1000 EVM is powered by 5V 1A power from a DC jack, when the power selection switch is closed to position 1. The AWR1443 EVM is powered by 5V 1A power. The LED DS1 is on. The PC can detect all the COM ports of  DCA1000 EVM and AWR1443 EVM.

③The DCA1000 EVM is powered by 5V 1A power from a DC jack, when the power selection switch is closed to position 3.The AWR1443 EVM doesn't have external 5V power, just simply connected with DCA1000 EVM through 60-pin high density connector. The LED DS1 is off. But the DCA1000 EVM is so hot that I am worried whether there is any problem. Also, the PC cannot detect the two COM ports of  AWR1443 EVM.

 Please help me with detailed instruction.

Thank you very much,

Best regards,

Simon
