Hi Swathy,

Since the issue has been resolved with the DK, i will close this tix and open a new one for my custom board.

Thanks

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.?

Swathy

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

* SPDX-License-Identifier: LicenseRef-Nordic-5-Clause

/ {

chosen {

zephyr,shell-ipc = &ipc0;

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>;

&gpio_fwd {

dfe-radio {

gpios = <&gpio0 4 0>,

<&gpio0 5 0>,

<&gpio0 6 0>,

};

I have kept the cpunet overlay as

&uart0 {

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 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..

[quote user="Jesbanda"]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. [/quote]

Glad to know that it worked.

Swathy

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,

I am not exactly sure what the issue is.. I checked with my colleague again and was informed that the CMW should be fine with the com port by itself.. Could you make sure if you are using UART and not HCI.? This might also be an issue on the CMW side.. Could you also check with R&S if that's the case.?

Swathy

i have tried both of these with no success. i have also tried directly to the UARTs with no success.

Is DTM only use with a MCU? I see both network and app so I don't know if i need to use a specific one because assigning the UART pots and connecting them doesn't work.

Hi Jesse,

I checked with an expert regarding this.. It depends where the DTM UART pins have been set. Please do check the DTM plugin in nRF Connect first. It should be one if these:

Thanks Swathy,

Any update on this issue?

I have tried using the UART with a FTDI cable but was unable to recognize the IC.

Hi Jesse,

The DTM sample is made to communicate over serial and not through the USB.. I believe the issue might be that the tester expects a firmware that communicates using USB and that you might need to try to configure the CMW270 to use serial.. I am not familiar with CMW270 and right now there are not many people that I can check with regarding this since it is the holiday season and the experts in this regard is out of office.. I will confirm if this is the case and get back to you once they are back.

Best Regards,

Swathy
