Do you have a tool to convert a file image between bin and hex formats?
Yes. Use Simplicity Commander to convert between bin and hex formats. Simplicity Commander is packaged with Simplicity Studio (www.silabs.com/simplicity).
The command to do this is demonstrated below:
C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\commander>commander convert aba.hex -o aba.bin
Parsing file aba.hex...
Writing to aba.bin...
