Include Dname in index
The pack index does not appear to include Dname part numbers, only Dvariant.
For instance, the NXP MIMXRT1052_DFP pack has a Dname of "MIMXRT1052xxxxB" with several Dvariants, including "MIMXRT1052CVJ5B". Only the Dvariant names are present in the index.
This is intentional.
You can probably blame me for this bit of confusion in CMSIS-Pack specification. The necessity for the definition of variants came in after the initial version and strongly pushed for by some partner feedback.
Once we have a variant defined for a device, the Dname attribute string becomes a "group name" (just like Dfamily and DsubFamily) and the Dvariant attribute string becomes the name string by which the device is referenced/selected.
This means that in the tools you can really only select the devices specified as <variant>
MIMXRT1052CVL5B
MIMXRT1052CVJ5B
MIMXRT1052DVL6B
MIMXRT1052DVJ6B
From a tooling perspective the device index must only list 'devices' regardless of whether specified by a <device Dname=""> or <variant Dvariant=""> tag (leafs in the description tree)
In the tools every project target specifies the Device as: Dvendor + Dname
(where Dname is the string specified by Dname or Dvariant in the <devices> description!)
Note:
I don't yet understand why NXP chose to define these as variants rather than devices.
The reason why it does not make sense to refer to a device by the name MIMXRT1052xxxxB is because this would not be specific enough e.g. for pin configuration tools. But often it also matters for conditional compilation of device header files
<compile header="fsl_device_registers.h" define="CPU_MIMXRT1052CVL5B"/>
I hope this explains it. I do appreciate it is not a great design.
