Part Number: IWR1642BOOST
Other Parts Discussed in Thread: UNIFLASH, IWR1642

Hello，

    

        I used the Uniflah tool to flash  the IWR1642 Boost.  But,During the download，I was uncarefully ,  touched the USB cable, and then the uniflash programming was stoped.

So I turned off the uniflash, and  programming again.

      However, It cannot nolong to  flash programming  again , I try many times, but it still failed (I have  try to restart Power  too )

     I checked  all the power supply of my board(5V, 3.3V ,1.2V ,1.8V ,1.3V ), and they are right.

     What should I do to repair my IWR1642 Boost? There is another way to recovery ?

     The  Uniflash  tool  display  the failure informationis  as follows (there are still two  UART when The IWR1642 Boost connect to PC, but it  can not be detected when use  the Uniflash tool flash programming)

       The Powered board picture show as below; there two led are lighted,DS2 and DS4;

        I am a hardware engineer，and I have checked the power,It is OK ;  So I think there are something wrong during the downloading;

        
       And What I'm  really worried  aboat is that  What if we meet the same problem In my mmwave Rodar product,

    we  are using  IWR1642 to design a new product , for people counting,

    Hi, Cheers, Akash

    I have solved the problem, I Uninstalled the "UniFlash "tool, and reinstalled it , then I can flash programming successfully ;
    So I think Maybe It is a bug of "UniFlash "tool, the last configuration is not cleared up?

    thanks
