Hi,

Sorry for the delay.

Can you please provide me more details about the tool used ?

To do that you must:

Under CodeWarrior IDE (classic)

Start the IDE and click on Help | About Freescale CodeWarrior.

Click on Installed Products

Provide us all info displayed.

Or you can save them in a txt file.

Under Eclipse IDE

1- Start Eclipse and click on Help ¦ Freescale Licenses

The Status column gives the status of the license.

Under Product, select it and click on details.

A new dialog show up giving license details.

Provide us all info displayed

2- Start Eclipse and click on Help ¦ About CodeWarrior Development Studio

Under Installed Products, you will see the version used.

Can you please share us the source file generating the error ?

Regards

Pascal

Morning,

My problem was of vle instructions support in gcc not freescale compiler. The vle patch is present but gcc has not included in its main stream powerpc compiler toolchain because it was somehow breaking support for some non-vle supporting powerpcs. Vle patch , however, was included in the codebench csgnu gcc version 2013.

Regard,
