imx8mq+Android9.0:What is the difference between evk_8mq-userdebug and evk_8mq_drm-userdebug?

[传策薛]

Hi community:

   What is the difference between evk_8mq-userdebug and evk_8mq_drm-userdebug? 

    When I "lunch  evk_8mq_drm-userdebug; make", there is a error:

ninja: error: 'vendor/nxp/drm_artifacts/playready/Samples/devcert.dat', needed by 'out/target/product/evk_8mq/vendor/playready/devcert.dat', missing and no known rule to make it
09:05:47 ninja failed with: exit status 1

Where can I get "vendor/nxp/drm_artifacts/playready/Samples/devcert.dat" ?

Hello Mr Xue,

(1)  evk_8mq-userdebug:  this is a our standard release version.

(2)  evk_8mq_drm-userdebug:Android team adds protection to DRM stream on the basis of standard version.

probably you can add some lines below to BoardConfig.mk, then try to compile it!

......

ifeq ($(PRODUCT_IMX_DRM),true)
BOARD_SEPOLICY_DIRS += \
       $(IMX_DEVICE_PATH)/sepolicy_drm
endif

......

If you still meet error, compile standard version, please!

Have a nice day!

BR,

Weidong
