I have followed the document that you suggested Section 6 Kinetis Design Studio Updates in C:\Freescale\KDS_3.0.0\doc\KDS_Release_Notes.pdf. But when I update the eclipse something error happened as shown as followed:
An error occurred while collecting items to be installed
session context was:(profile=DefaultProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
Unable to read repository at http://freescale.com/lgfiles/updates/Eclipse/KDS/binary/com.freescale.processorexpert.ksdk-1.2.0.sp_....
Unexpected end of ZLIB input stream
Please tell me what's wrong with it?
