env.BoardConfig() does not work for custom boards in extra scripts of libraries.

[JelleRoets]

What kind of issue is this?

• PlatformIO Core.
  If you’ve found a bug, please provide an information below.

Configuration

Operating system: OSX 10.14.6

PlatformIO Version (platformio --version): PlatformIO, version 4.1.0

Description of problem

I have a library with an extraScript. This script wants to read the current BoardConfig using env.BoardConfig(). However when I use a custom board, which' definition lives in the 'boards' folder of my project root folder, env.BoardConfig() in my library script does not work anymore and throws an error: UnknownBoard: Unknown board ID 'myboard'.

Steps to Reproduce

1. Create a custom board
2. Create a library with an extraScript, in that script use env.BoardConfig()
3. try to run platformio

Actual Results

throws error: UnknownBoard: Unknown board ID 'myboard'.

Expected Results

returns the correct current board config

Additional info

I think the culprit is

platformio-core/platformio/project/config.py

Line 376 in 3c796ca

project_dir = os.getcwd()

when the script for the custom library is executed, the cwd changes to the folder of the library, hence the get_optional_dir("boards")

platformio-core/platformio/managers/platform.py

Line 619 in 3c796ca

self.config.get_optional_dir("boards"),

will return a path that contains the path of the library instead of the project path, hence it can't find the custom boards folder and throws an error it can't find the custom board.

Please re-test with pio upgrade --dev.

unfortunately it didn't solve the problem, I still get the same error.
In the mean time I pushed my example, so in order to reproduce

1. check out https://github.com/JelleRoets/AtmelStart_PlatformIO
2. running pio run in the ArduinoZeroASF example (https://github.com/JelleRoets/AtmelStart_PlatformIO/tree/master/examples/ArduinoZeroASF) results in the following error:

UnknownBoard: Unknown board ID 'myboard':

Please re-run pio upgrade --dev

Thanks for the report!

[JelleRoets]

yep that fixed it, thanks for the quick respons!
