How do I change which package of a particular part Configurator uses? What do I do if Configurator does not list the package I need?
The package used by Configurator can be changed by editing the .hwconf file. Under the device tag, there will be a name field that includes the package. In the example below, QFN32 can be changed to QFP48:
<device:XMLDevice xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:device="http://www.silabs.com/sls/hc/document/device.ecore" name="EFM8UB20F64G-A-QFN32" partId="com.silabs.mcu.si8051.efm8ub2_g.efm8ub20f64g">
