Comprehensive information about SDK SW components and SDK release describing YML can be found in the Yml data record guide here:
Example
We need to build a dependency from the eIQ component to the CMSIS DSK Library component.
It is needed to add the dependency definition into the __requires__ section of the dependent component into YML:
middleware.eiq.cmsis_nn:
section-type: component
__requires__:
- middleware.eiq.ui_control
CMSIS_DSP_Lib.arm_cortexM7lfdp_math
contents:
cc-include:
- path: middleware/eiq/cmsis-nn/Include
files:
...
Such dependency will be reflected on the MCUXpresso website and also in the SDK manifest file:
<component id="middleware.eiq.cmsis_nn.MIMXRT1052" name="CMSIS-NN" brief="CMSIS-NN library" version="1.0.0" full_name="CMSIS-NN library" devices="MIMXRT1052xxxxB" dependency="platform.CMSIS_DSP_Lib.arm_cortexM7lfdp_math.MIMXRT1052" category="Machine Learning/eIQ" user_visible="true" type="middleware">
<source path="middleware/eiq/cmsis-nn/Include" target_path="CMSIS/NN/Include" type="c_include">
<files mask="arm_nnfunctions.h"/>
<files mask="arm_nnsupportfunctions.h"/>
<files mask="arm_nn_tables.h"/>
</source>
How to verify that the dependency has been correctly described it will really work in the SW tools?
- You can generate an SDK package with this component and check the behavior in the MCUX IDE.
- You can check SDK release data tables - output of the first two stages of the SDK Generator, where the component dependencies are resolved:
-
Run “ruby all_evkxxx.rb -a eiq -c superset -o target_dir“, in the target_dir/devices/<xxxx>/<xxxx>.yml, you can check under your middleware.eiq.ui_control, it should have the “CMSIS_DSP_Lib.ui_control” in the “web_requires”, like
middleware.eiq.ui_control:
section-type: component_support
__requires__:
- board.evkbimxrt1050
- board.evkmimxrt1060
component_info:
common:
ui_name: eIQ
ui_description: eIQ machine learning
ui_category: Middleware
ui_control: 'True'
ui_control_default: 'False'
ui_release_specific: 'True'
full_name: eIQ
class: Machine Learning
version: 1.0

web_requires:
- CMSIS_DSP_Lib.ui_control

- You can ask the SWPE team to deploy your experimental SDK release superset with this change on an MCUX sandbox website - follow instructions described here: https://confluence.sw.nxp.com/display/MCUXSDKB/Deployment+of+an+experimental+SDK+release+image+on+th...
