Hi Chandrasekar,
You're using CW for MPC55xx/56xx V2.10 and CW for MCU V10.6.4.
Both versions are supporting MPC56xx family.
The V2.10 was released in Q1 2012 whereas the MCU V10.6.4 was released middle of 2015 and some patches were released recently and can be applied on V10.6.4.
It's very difficult to be sure the application is exactly the same on 2 versions.
Why ?
First the build tool chain is not the same.
On V2.10 the compiler version 4.3 build 224 is used whereas on MCU V10.6.4 it's the version 4.3 build 285.
If your application is running fine with V2.10 but not on MCU V10.6.4 we should may be perform some tests on our side.
Is it possible to share with us more information ? ... for instance the project.
