Segger Embedded Studio doesn't work

[Yusuke]

OS: Mac

I installed nrf v1.2.0 and Segger Embedded Studio v4.42a. I can't open project and it causes error.

I can open projects with this config on SES v4.42a and nrf v1.1.0.

Any help?

Hi,

 

It looks like CMake finds python 2.7 instead of the executable pointed to in SES.

Since you mention it works in ncs v1.1.0, it could be that your local cache is in a bad state. Could you try deleting it?

Here's how you do that in macos:

rm -rf ~/Library/Caches/zephyr/ToolchainCapabilityDatabase

 

Note that I would recommend that you use SES nordic edition v4.30c instead of v4.42 at this time, due to issues discovered here (for windows atleast, might behave different on MacOS):

Kind regards,

Håkon

I did it but the same result.

rm -rf ~/Library/Caches/zephyr/ToolchainCapabilityDatabase

Hi,

 

This is strange. Could you check what version "python" defaults to on your side?

"python --version"

 

If this points to python2, that might be the issue. Not sure why CMake is picking up the default even with the -DPYTHON_EXECUTABLE override.

Here's a way to override zsh python version locally (only need to run this once, and it'll be loaded every time you open a zsh terminal):

echo "alias python=/usr/local/bin/python3.7" >> ~/.zshrc

I'll include one for bash as well, in case you're using that:

$ echo "alias python=/usr/local/bin/python3.7" >> ~/.bashrc

 

Kind regards,

Håkon

[Yusuke]

$ cd nRF9160/ncs
$ python --version
Python 3.7.2

I'm using v3.7.2, not python2

[Yusuke]

Mac OS, nrf v1.2.0, Segger Embedded Studio v4.30.c => the above error

Mac OS, nrf v1.1.0, Segger Embedded Studio v4.30.c => can open projects

I think v1.2.0 has some bugs in python usage.

Hi,

 

I have tested with Catalina, and cannot get it to wrongly identify python to python2.7 at my end, unfortunately.

Which version of macos are you running?

 

Kind regards,

Håkon

[Yusuke]

I upgraded Mac OS to Catalina. I also deleted pyenv and am using python3.7 installed by homebrew. Now I get this error.
