IWR1443: Program the IWR1443 using TMDSEMU110-U

Part Number: IWR1443

Hello,

I have a IWR1443 based custom PCB which I am trying to program using TMDSEMU110-U. I have connected UART port RX and TX to corresponding Auxillary port TX and RX and have connected a common GND. I have ensured SOP setting to the flasing setting. I am unable to program using UNIFLASH. It says it is unable "Not able to connect to serial port". Are these connections and my procedure correct to load the program?

    Did Adrian's suggestion above also fail?

    Can you confirm that you were able to program the board before the ECOs?

    Can you also send a picture of your setup?

    Hello,

    I have just ordered the FTDI board which Adrian has suggested. 

    I did not understand what is ECOs.

    I have attached some pictures of my setup, I have tried both giving 5V from external supply and also from the XDS110 probe. Kindly check if I am doing any mistake. I strongly feel so because I have tested the same setup on IWR1642BOOST aswell.

    Hi,

    Did you solder on  the 0-ohms resistor R169 and R166?

    if you look at the schematic  (snippet below), the RX and TX route to the header includes these resistor and they are by default DNI (do not include)

    Hello Charles,

    I can confirm I have shorted R169 and R166. I have checked the continuity of signal aswell.

    Hi,

    Maybe the picture isn't clear. But it seems you have the RX and TX cable on the 5V part side of the header instead of the 3V3 side of it.

    You need to flip the sides of the connection.

    Hello,

    Yes I have connected perfectly as schematic and checked as attached picture. Yet the result is same. I think there is some issue with the debugger. I have ordered Adrian's suggested FTDI cables. Lets hope they work. I will keep the post updated.

    You can also try a different EVM if you have one

    Hi,

    Do you have any update?

    I assume you were able to resolve this and will be closing the thread. Please reply if you still need assistance or make a new post referencing this one.

    Hello,

    I have received the suggested module and tested it. The good new is that it works perfectly on IWR1642BOOST and doesnt work on IWR1443BOOST. It could be some issue I am working on IWR1642 so I will go ahead with the situation. Thanks for the support.
