Thank you for your help.
I installed the CW_MCU_v10.1_Update_1.0.1 for Windows, now I see in the Processor Expert README.TXT file the Processor Expert version is 5.1.
But, opening my BSP_PE project, I see that for Kinetis K60 only three CPU with 144-LQFP package are available (and no more the 144-MAPBGA package!). How to get the 100-LQFP package?
Maybe is it a CodeWarrior license issue? Because I am working with CodeWarrior Special Edition 10.1, while the Product Content for Kinetis family in the Processor Expert README.TXT file is specified for a license BASIC.
Furthermore, I have now the folder "[CW_ROOT]\MCU\ProcessorExpert\CPUs\MK60N512LL100", so the 100-LQFP package for the Kinetis K60 is actually installed.
