Hi, i am working on below environment,Target - Renesas RH850-U2A6, Compiler - GHS v2018.1.5, Debugger hardware renesas e2, and debugging tool Multi 7.1.6. when i compiling code in IBM RTRT tool i am getting more undefined variable error because the TDP which i am using is supported for GHS compiler v2003. Please provide any TDP script for above environment

Hi,

Are you looking for a TDP for your target environment? 
The TDPs coming out of the box with the product are located in the Test RealTime installation (since 9.0 renamed in DevOps Embedded ):
<Installation directory>/targets see tdpList.html.
It's list of TDPs which can be use as base for customisation.

There is always a customisation needed, sometimes is straight forward and sometimes more complex.

The problem you are facing seems occurring during the build but not enough information to give you a lead for you investigation.

Also, even TDP customisation is out of the scope of support you can open a support ticket to ask for some help.
