nRF Connect SDK Linux Installation & Compiling Failure

[Salih Onur ZORLU]

Hi,

I installed nRF Connect SDK manually by following the instruction in this page. I had 2 problems but I did a trick and it seems it solved for now. However I need to know for the future.

OS: Ubuntu 22.04

ncs: In home directory and the structure is lie below.

ncs
 |___ .west
 |___ bootloader
 |___ modules
 |___ nrf
 |___ nrfxlib
 |___ zephyr
 |___ ...

SDK: In home directory with the name like zephyr-sdk-0.14.1 and also isntalled 0.15.1 at the same time. However VSCode has given an error that v2.2.0 requires zephyr-sdk-0.15.1. It couldn't detect automatically. I have checked the $PATH env. var. There is no toolchain variable in it, but I don't understand how VScode can find 0.14.1. Anyway I renamed folders 0.14.1 to 0.15.1 and 0.15.1 to 0.14.1. Now VSCode doesn't give any error and it accepts. It seems that this problem has been solved temporarily.

The setting VSCode extention:

nRF Connect SDK: 2.2.0 (/home/soz/ncs)        => as detected

nRF Connect Toolchain: PATH (Zephyr SDK: /home/soz/zephyr-sdk-0.14.1)     => as detected. 0.15.1 couldn't detected so as mentioned above renamed folder.

Output of PATH env.

soz@salihonur-lnx:~/ncs/zephyr$ echo $PATH
/home/soz/ncs/zephyr/scripts:/home/soz/.local/bin:/home/soz/gn:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/home/soz/nRF52/gcc-arm/bin
soz@salihonur-lnx:~/ncs/zephyr$

Output of ZEPHYR_BASE variable:

soz@salihonur-lnx:~$ echo $ZEPHYR_BASE

soz@salihonur-lnx:~$ cd ncs/zephyr/
soz@salihonur-lnx:~/ncs/zephyr$ source zephyr-env.sh 
soz@salihonur-lnx:~/ncs/zephyr$ echo $ZEPHYR_BASE

soz@salihonur-lnx:~/ncs/zephyr$ echo $CONF_FILE

soz@salihonur-lnx:~/ncs/zephyr$ echo $DTS_OVERLAY_FILE

Error of compling "blinky" example in VSCode:

Questions:

1. I guess the compiler can't find PATH variables. Only ZEPHYR_BASE variable comes if "source zephyr-env.sh" is executed. What are the default location of these variables below? I can define them manually.
   

   BOARD

   CONF_FILE

   SHIELD

   ZEPHYR_BASE

   ZEPHYR_EXTRA_MODULES

   ZEPHYR_MODULES

   ZEPHYR_BOARD_ALIASES

   ZEPHYR_SDK_INSTALL_DIR

   ZEPHYR_TOOLCHAIN_VARIANT

   {TOOLCHAIN}_TOOLCHAIN_PATH

2. Where can I change the toolchain path?

[Marte Myrvold]

Hi,

The environment variables you need to define are:

ZEPHYR_TOOLCHAIN_VARIANT=zephyr

ZEPHYR_SDK_INSTALL_DIR=<path to zephyr-sdk-0.15.1>

After you have set this, you should make sure to create a new workspace in VS Code so you do not use previous workspace settings, and delete the build folder before building again.

Best regards,

Marte

[Salih Onur ZORLU]

Hi Marte,

I set those environment variables but still having problem. I closed Workplace in VScode, re-installed nRF Connect extention and created new blinky project.

Here are the line which are appended into .bashrc file.

export PATH=${HOME}/zephyr-sdk:"$PATH"
export ZEPHYR_TOOLCHAIN_VARIANT=zephyr
export ZEPHYR_SDK_INSTALL_DIR=${HOME}/zephyr-sdk

export GNUARMEMB_TOOLCHAIN_PATH=${HOME}/nRF52/gcc-arm/bin

If ı remove ZEPHYR_TOOLCHAIN_VARIANT and EPHYR_SDK_INSTALL_DIR variables in .bashrc file then VSCode can find the path automatically however this time I get gnu-arm variant error even if it is already set with GNUARMEMB_TOOLCHAIN_PATH variable in the .bashrc file.

Hi,

The error you get when building on command line is because you are building an out of tree application without having ZEPHYR_BASE set in your environment variables. Set ZEPHYR_BASE=${HOME}/ncs/zephyr and you should not get the west error anymore. Please try again after fixing this and see if you get the same error there as in VS Code.

I will look at the support information from VS Code and get back to you.

Best regards,

Marte

[Salih Onur ZORLU]

Now the build function works. However I'm still getting the compiling error same as VSCode.

[Sigurd Hellesvik]

Hi,

I will continue helping in this case.

Can you run the following command and upload the log file?

cd ncs/zephyr
tree > tree_log.txt

Regards,
Sigurd Hellesvik

[Salih Onur ZORLU]

Hi Sigurd,

Here is the log file: https://easyupload.io/8mll37

[Sigurd Hellesvik]

From the log, I can find the file I thought were missing, so that should be fine.

Can you try  to build the zephyr/samples/hello_world sample, and see if you still get the same error?

I had 2 problems but I did a trick and it seems it solved for now.

By the way, what was this trick?

Regards,
Sigurd Hellesvik

Unfortunately same. Here is the output.

I found something interesting. If I set ZEPHYR_TOOLCHAIN_VARIANT=zephyr then VSCode can't find the toolchain path even if ZEPHYR_SDK_INSTALL_DIR=${HOME}/zephyr-sdk is already set.

About the tick:

At the begging there were 2 version zephyr-sdk-0.14.1 and zephyr-sdk-0.15.1 in the home directory. VScode. By the way only ZEPHYR_SDK_INSTALL_DIR variable was set to 0.15.1. However VSCode couldn't find 0.15.1, it was finding 0.14.1. Then I did a trick and changed the folder name. It solved.

A few days later I removed 0.14.1 named folder then VSCode could find 0.15.1. Then I figured out that VSCode looks up folder names in ascending. Finally I removed all sdk folder and created a new folder as zephyr-sdk with the 0.15.1 version.

I think VSCode automatically finds the folder with the name zephyr-sdk. It doesn't accept underscores or a name in different format.

I will try another installation on a virtual machine and I will record it. I can upload it to Youtube and share the link as well.

Hope to find a solution next week, happy new year in advance.

This would be very useful indeed!

If you intend to use a virtual machine to do this, maybe do one for using our Automatic install instead of the manual install also?
The Toolchain Manager should be quite fast, and it would be interesting to see if it works.

Happy new year!

Hi Sigurd,

I already installed it with automatic tool. Unfortunately it didn't work and then I tried to fix it manually.

I recorded 2 videos and saw that teh problem is caused by the automatic installation. I don't know if I did something wrong. Please check it.

In fact, there is a missing point in the manual installation guide that VSCode gives an error about missing nrfjprog even if nRF Command Line Tools is already installed (with deb file in Ubuntu 22.04). Segger JLink support has to be installed seperately.

I re-installed Ubuntu OS on my computer and did nRF manual installation. It works properly now.

PS: The videos can only be accessed via the link. It is unlisted on Youtube.

Automatic installation:

Manual installation:

[Sigurd Hellesvik]

Hi,

I will have a look at these videos at Wednesday.

Sigurd Hellesvik

[Sigurd Hellesvik]

Hi,

To use the command line from the Toolchain Manager, it is easier to open a terminal from the Toolchain Manager, to get all the environment variables set correctly:

For Linux this should say "Open Terminal" instead I think.

Here. I think you should start by installing JLink from the J-Link Software and Documentation Pack.
I agree that this should be better documented. But if you got time, give it a try and see if it works.
If you are still missing nrfjprog after, you can install it from https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools

From the Manual Installation, it seems like things are working fine, except for the jlink and nrfjprog error. Right?
For information: JLink and nrfjprog are used to flash and debug the device.
You will be able to build project withouth these, just not flash them to the device.

Sigurd Hellesvik
