Hi,
I am trying to configure GPIOs with a custom DTS file, for initial bring-up and testing of the PCBA prior to higher-level development. During compile, I am getting a message "FATAL ERROR: command exited with status 1: 'c:\ncs\toolchains\v2.0.0\opt\bin\cmake.EXE' --build 'c:\nordic\V1_man-in-middle_new\build'", but there I am not seeing any issues in the 'problems' tab of VS code.
If I comment out line 42, the compile executes cleanly.
if (!device_is_ready(led0.port)) {
return;
}
Do you have any recommendations of where to start looking to debug this?
