"Couldn't find Zephyr root" both SEGGER and VsCode

[Mr.Newlove]

Hello all,

Lost my VM that had a working installation and just setting everything back up.

After installing SDK 1.8.0 and all of the extensions for VsCode. Now both SEGGER and VSCode cannoot find the Zephry root and I cannot find it on disk?

This was not a problem in the past, any ideas?

Thanks

Edit: Another problem... like all of the examples are missing?? searched for serial_lte_modem and it comes up with nothing. Even just searching serial, or application comes up with nothing useful?

Edit2: I installed the most recent 3 releases and none have a zephyr folder anymore?!?!?

Hello Kyle,

Mr.Newlove said:

Everything complies fine when using a regular sample, but all applications fail in some way.

Let us start from the beginning here. Are you now able to create a free-standing application based on the Serial LTE Modem and configure/compile/flash it successfully in VS Code for the nrf9160dk_nrf9160_ns, without any modifications?

If not, please share a build log from the “Terminal” window.

Regards,

Markus

no, when I say regular sample; I mean blinky/hello world work, but anything in the "applications" dir for sample fail.

Just as one more thing to try I made sure to close the entire workspace in VS Code and that got the basic one compiling now.

But if i create a new board and change nothing in the configuration I get:

All I need to do is get this thing talking on two serial lines again with GPS and cellular location services enabled. I had it working in VM before, but the file got messed up when transferring to a new machine.

Before all I did was use the circuitdojo_feather_nrf9160_ns board with an overlay file like this:

&uart0 {
	status = "okay";
	current-speed = <115200>;
	tx-pin = <24>;
	rx-pin = <23>;
	cts-pin = <0xFFFFFFFF>;
	rts-pin = <0xFFFFFFFF>;
};

[Mr.Newlove]

Mr.Newlove said:

And if i compile for something like the basic "circuitdojo_feather_nrf9160_ns" I get:

If i try to directly address this one, i change this in prj.conf:

# Segger RTT
CONFIG_USE_SEGGER_RTT=n
CONFIG_RTT_CONSOLE=n
CONFIG_UART_CONSOLE=y
CONFIG_LOG_BACKEND_RTT=n
CONFIG_LOG_BACKEND_UART=n

I get a lot further:
