nRF5340 DK does not connect to CMW270/500

JesB

I am trying to test the nRF534 DK with my R&S CMW270 but i am not able to connect. i can see the Jlink ports but could not get a connection with either of them. I was able to program the DK to DTM mode using the nRF USB port but the CMW doesn't recognize it. It sees it as "Nordic Remote Shell sample." 

Do you a driver i can use or different instructions to use the CMW?

    Hi Swathy, 

    I was able to get the our 5340-DK working and now i can verify it is in DTM mode by using nRF Connect. my CMW270 also now recognizes it and I'm able to measure TX/RX. 

    I had to create a new build and reprogram it again but it seems to be working now. Maybe I didn't do it correctly the first time but I didn't get any errors when programming it. 

    But now I wanted to test my board that's using a nRF5340-CLAA, and I am running into the same issue. I have modified the nrf5340dk_cpuapp_common-pinctl.dtsi to the pins i want to communicate with. I'm using a 1.8 FTDI cable since we are using 1.8V to power the nRF5340. 

    But i can't get any communication and the nRF Connect DTM app doesn't see it. 

    below is how i set my UART lines to the desired pins on the "nrf5340dk_cpuapp_common-pinctl.dtsi":

        uart0_default: uart0_default {
            group1 {
                psels = <NRF_PSEL(UART_TX, 0, 27)>;
            };
            group2 {
                psels = <NRF_PSEL(UART_RX, 0, 28)>;
                bias-pull-up;
            };
        };

        uart0_sleep: uart0_sleep {
            group1 {
                psels = <NRF_PSEL(UART_TX, 0, 27)>,
                    <NRF_PSEL(UART_RX, 0, 28)>;
                low-power-enable;
            };
        };

    Hi Jesse,

    You had problem with programming your DK with the DTM firmware.? make sure to clear the chip prior to programming it [ nrfjprog --recover] and it should work fine..

    Glad to know that it worked.

    Hi Swathy,

    Yes, i was able to get out DK working. 

    But now i am working on my custom board. and we are using the nRF5340-CLAA. 

    I have program the DTM code to our custom board but i cannot communicate with the UART-DTM. 

    I have changed the defaults UART pins for my board but i don't get any communication from from it. I am using the nRFconnect DTM to verify communication.

    Hi Swathy,

    I am still having issues using DTM on my custom board with the nRF5340. i have modified the cpuapp overlay to the TX/RX pins i have for UART but I still cant get any communication when trying to use the DTM in NRF Connect foe Desktop. Any suggestions?

    I have change the CPUapp overlay to

    / {

            ncs,remote-shell-uart = &uart0;
        };
    };

    &pinctrl {
        uart0_default: uart0_default {
            group1 {
                psels = <NRF_PSEL(UART_TX, 1, 7)>;
            };
            group2 {
                psels = <NRF_PSEL(UART_RX, 1, 8)>;
                bias-pull-up;
            };
        };

        uart0_sleep: uart0_sleep {
            group1 {
                psels = <NRF_PSEL(UART_TX, 1, 7)>,
                    <NRF_PSEL(UART_RX, 1, 8)>;
                low-power-enable;
            };
        };
    };

    &uart0 {
        status = "okay";
        current-speed = <19200>;
        pinctrl-0 = <&uart0_default>;
        pinctrl-1 = <&uart0_sleep>;
        pinctrl-names = "default", "sleep";
    };

    &gpio_fwd {
        dfe-radio {
            gpios = <&gpio0 4 0>,
            <&gpio0 5 0>,
            <&gpio0 6 0>,
            <&gpio0 7 0>;
        };
    };

    I have kept the cpunet overlay as

    / {
        chosen {
            ncs,dtm-uart = &uart0;
        };
    };

    &uart0 {
        status = "okay";
        compatible = "nordic,nrf-ipc-uart";
        ipc = <&ipc0>;
        ept-name = "remote shell";
        current-speed = <19200>;
    };


    &radio {
        status = "okay";
        /* This is a number of antennas that are available on antenna matrix
         * designed by Nordic. For more information see README.rst.

        dfe-antenna-num = <12>;

    Hi Jesse,

    It should work properly if all you have done is change the UART pins according to your hardware.. Which version of the SDK are you using.?

    Regards,

    Swathy
