NRF9160KD UART configuration

RE: NRF9160KD UART configuration

It's strange that it doesn't build for you. I put CONFIG_BOARD_NRF9160DK_UART0_ARDUINO=y in prj.conf, built from the command line for the nrf9160dk_nrf52840 board and it worked fine. I did not get the "warning: attempt to assign the value 'y' to the undefined symbol BOARD_NRF9160DK_UART0_ARDUINO" message. Can you try building with west/command line and see if you still get the error?

It doesn't work, syntax error.

I tried to build the hello_world project on board: nrf9160dk_nrf52840 with overlay file. I tried your code and the code I found in my build folder dts file.

vcom0_pins_routing: switch-nrf91-uart1 {
   compatible = "nordic,nrf9160dk-optional-routing";
   control-gpios = <&gpio1 14 (1 << 0)>;
   status = "okay";
  };

I determined that this setting has been moved into the device tree. The setting for this can be seen in the nrf9160dk_52840.dts file and can be adjusted using a .overlay file to change the routing of the UART pins.

vcom0_pins_routing: switch-nrf91-uart1 {
compatible = "nordic,nrf9160dk-optional-routing";
control-gpios = <&gpio1 14 GPIO_ACTIVE_LOW>;
status = "okay";
};

I tried to build and flash the hello_world project from Zephyr/sample, but still no luck. Same error happened.

C:/ncs/v1.5.0/zephyr/samples/hello_world/prj.conf:2: warning: attempt to assign the value 'y' to the undefined symbol BOARD_NRF9160DK_UART0_ARDUINO

which component controls U7 (nRF91_UART1_CTRL)? I found limited info from

You need to build the board controller for nrf9160dk_nrf52840, and put the CONFIG_BOARD_NRF9160DK_UART0_ARDUINO=y in prj.conf. You can build the Zephyr "hello_world" sample.

RE: NRF9160KD UART configuration

No, it doesn't work. Here is the error I got.

C:/ncs/v1.5.0/nrf/samples/nrf9160/gps_bc_test/prj.conf:13: warning: attempt to assign the value 'y' to the undefined symbol BOARD_NRF9160DK_UART0_ARDUINO

It looks like there is no such param named CONFIG_BOARD_NRF9160DK_UART0_ARDUINO, which is kind of what I expected because I can't find it in the lib file, config.c.

With that been added to prj.conf file, the Segger Embedded Studio doesn't allow me to create the solution. I got

create_nordic_project.py failed (1) error

here is the full log file.

Hello,

[quote user=""]So what's the current parameter I should change?[/quote]

It has changed name to CONFIG_BOARD_NRF9160DK_UART0_ARDUINO.

[quote user=""]Another question I have is, to change the serial comm baudrate, what's the proper method to do that?[/quote]

You can change the current-speed parameter in overlay

&uart0 {
  status = "okay";
  current-speed = <115200>;
  tx-pin = <28>;
  rx-pin = <29>;
};
