As MCUs continue to become more complex especially when creating applications to enable the Smart Society, and therefore the Software becomes more complex as well. As a result most of the complex program doesn’t fit in the free code size limited version of the CubeSuite+ and requires tool investment. Solution: “This class will help you how easy is to Migrate RL78 Cubesuite+ code to e 2 studio/GNU compiler”. ‘Enabling The Smart Society’

All rights reserved.17 Common Issues My program doesn’t go to interrupt service routine I defined in the Cubesuite+? -> Make sure the ISR function name has been ported from __Interrupt qualifier to INT qualifier for GNU compiler. How do I fix the error “ “XXX” undeclared (First use in the function)” while building the project? -> Check if iodefine.h, and iodefine_ext.h files are included in the *.c files which shows the error message. Can’t connect e 2 studio to RDK board for the debug session? -> Check the SW5 DIP-switch setting on the board as: 1:ON; 2:OFF; 3:ON ; 4:ON
