Hi:

I migrate one project, built on previous KDS version, to KDS3.0, which get a link issue:

see below log, the whole log is attached.

'Building target: AcmMuRataTest.elf'

'Invoking: Cross ARM C++ Linker'

Hi,

I don't see any libraries listed in your link commands.

Can you check if you have

-specs=nano.specs -specs=nosys.specs

specified in the linker settings to use the nano library with the no-sys option?

Have a look at https://community.freescale.com/docs/DOC-103698/edit?ID=103698 for additional details about migrating.

I hope this helps,

Erich
