Hello
When you install CodeWarrior for MPC55xx, you get a license for a 30 days evaluation period.
That means you can use the tools for free during 30 days.
Once this evaluation period has expired you will not be able to use the tools any more.
MPC55xx tools are not free.
Please contact your Freescale distributor or sales contact to get an official quotation to purchase the tools.
Thanks for your understanding.
