unrecognized platform - mvu

[Prem2255]

Hi, I have am out-of-tree project with a custom NXP board called 'mvu'. Board configurations are in /board/acme/mvu and 'west build' correctly identifies the board which builds and flashes to the target. Several ztests are located in /tests/ztest subfolders with their own prj.conf, CMakeLists.txt and testcase.yaml. When I run a test: '$ZEPHYR_BASE/scripts/twister -T tests/ztest/application/' it compiles and runs if the native_sim is specified in platform_allow but fails to compile if I specify my custom board in the platform_allow. 'ERROR - platform_allow in application.integration - unrecognized platform - mvu' I have the BOARD environment set to 'mvu'. I need to run the tests on the host and the target. Can someone please point me in the right direction? Many thanks.

Hi @Prem2255 ,
There is a related discussion at #99209 , checkout the .yml versus .yaml extension. Are you using the --board-root argument with Twister?
