Visual studio code - FATAL ERROR: Unable to parse input tree

[JoelWise]

I'm running into this build error. Help would be appreciated.

It seems you're using an older ncs version. I would try updating it 2.1+. I'd also make sure the vscode extension is up to date.

[JoelWise]

OK. I updated ncs and reinstalled the vscode extension. Seems to have worked.

I've added these lines to prj.conf to set a custom mac, saved, built, and flashed but the probe isn't set with this address. It's still picking a random one. Am I doing this correctly?

CONFIG_PRST_BLE_HAS_USER_DEFINED_RANDOM_STATIC_ADDR=y CONFIG_PRST_BLE_USER_DEFINED_RANDOM_STATIC_ADDR="f5:a0:80:fa:ed:2f"

[rbaron]

That should have worked I think. Maybe try doing a pristine build?

[JoelWise]

I set it via Kconfig too and that resulted in the same ouput into prj.conf. There is no option for a pristine build.

[rbaron]

Here's how to do a pristine build from VSCode:

I would also refrain from editing configs in the Kconfig editors while debugging, since the settings are lost once you clean the build. Just add the configs like you did to prj.conf. Make sure it's a clean git checkout before that too -- I see some extra stuff in the screenshot you posted.

I just tested your settings myself and it seems to work as expected:

Relevant changes to prj.conf:

CONFIG_PRST_SLEEP_DURATION_SEC=1 # Just for quick debugging
CONFIG_PRST_BLE_HAS_USER_DEFINED_RANDOM_STATIC_ADDR=y
CONFIG_PRST_BLE_USER_DEFINED_RANDOM_STATIC_ADDR="f5:a0:80:fa:ed:2f"

Output from the RTT console:

I set up an ESP32 to scan BLE advertisements and I can see the expected user-supplied address:

[JoelWise]

I tried a pristine build, fresh github clone, opening closing VSC. The mac config lines remain in prj.conf but still not working. Maybe I'll revisit this sometime later but for now I just used the legacy branch to get the power saving ble advertising changes onto my devices. Thanks for helping, though.

[rbaron]

If you revisit it later, check out the output of the RTT console like the one I sent above.

You can also try using Docker to build and debug your setup.

Feel free to reopen the issue if/when you revisit it. I'm also curious to figure out what happened there. Unfortunately I wasn't able to reproduce it.
