nRF9160 serial lte modem with custom board

[ALEJANDRO_CEIT]

Hello,

I am trying to use the LTE modem serial example on a customized board that communicates an NRF9160 SICA B1 with an external STM32 microcontroller through the UART interface. I'm working with VS Code extensions.

I did the following steps:

1. install toolchain 2.6.1 

2. install SDK v2.6.1

3. Create an application from sample (Serial LTE modem)

4. Create a "build configuration" --> Board = nrf9160dk_nrf9160_ns (there is no SICA B1 option) // Revision = 2  // configuration= use build system default

5. Build (It takes a very long time to finish)

it gives me some warnings, but the build seems to finish: 

      CMakeLists.txt --> No SOURCES given to Zephyr library: drivers__console

      prj.conf --> CONFIG_LOG_BACKEND_UART was assigned the value n, but got the value n. Missing dependencies: UART_CONSOLE

6. Open Devicetree Overlay file and adjust it to my needs:

               disable spi, buttons, leds ... 

               change uart0 pins to the pins assigned in my custom board

7. Edit build configuration to include the overlay modified

8. Build again

-- Configuring incomplete, errors occurred!
FATAL ERROR: command exited with status 1: 'C:\ncs\toolchains\cf2149caf2\opt\bin\cmake.EXE' -DWEST_PYTHON=C:/ncs/toolchains/cf2149caf2/opt/bin/python.exe '-Bc:\nordic\myApps\serial_lte_modem\build_1' -GNinja -DBOARD=nrf9160dk_nrf9160_ns@2 -DNCS_TOOLCHAIN_VERSION=NONE -DEXTRA_DTC_OVERLAY_FILE=overlay-external-mcu.overlay -DBOARD_ROOT=c:/nordic/myapps/serial_lte_modem '-Sc:\nordic\myApps\serial_lte_modem'

 

I'm desperate with this problem; I don't know how I could control the nRF9160 modem from my microcontroller using AT commands through the UART interface.

thanks in advance

best regards

Hey,

8. Build again

can you post the entire build log from the last build?
