Use the SCB implementation of the UART and not the UDB version.
Thanks for the reply i treid your suggestion and it worked but as in the previous post image i have other components too and as per my project designs i have to link uart udb on P3 and P3 and i2c on P0 amd P0 which is creating this error
find other image of project drawing and guide me with some solution.
The image allone is not very helpful. Can you post your complete project, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
