In certain situations the Save Build Settings report does not work correctly when using the CC-RX toolchain.

An error is thrown:

"Cannot invoke "String.toLowerCase()" because "fileSpecText" is null"

A possible workaround could be to set "Check the source code by MISRA-C" option to "No".

All toolchain projects:

Build error occurs when executing Build with a new Build configuration you added.

At that case, please specify the toolchain and device to your project.

After opening the project, this can be achieved via the Project Explorer, project context menu.

On this menu access the "Renesas C/C++ Project Settings" and use the "Change Device" and "Change Toolchain Version" features.

When using Smart Configurator project with GCC RX toolchain, the --gc-sections setting is unchecked when generating code.

If you wish to enable --gc-sections setting, please check this article https://llvm-gcc-renesas.com/wiki/index.php?title=RX_automatic_interrupt_vector_entry_usage to make sure it does not remove interrupt service routines.

When selecting the DSP core on Debug view, modifying the value of IO register on the IO Registers view will not take effective.

Workaround: Select CPU on Debug view and modify the DSP IO register correspondingly

In certain situations the errors that are displayed after a build will overlap the source line in the editor window. If this occurs scrolling the editor view up or down seems to resolve this.

If this becomes a common occurrence it is possible to stop this happening by switching off the code mining option.

This is available in the Window→Preferences page. In the section General→Editors→Text Editors. The option to switch off is named Show code minings for problem annotations. Change this setting to None.

Using Optimization Assistant Time measurement with GCC RX may cause the measurement unable to finish. The end address of function build from GCC RX may be different with the one in Disassembly view so Optimization Assistant cannot reach the end of function. If the measurement is too long to finish or unable to finish, just press "Cancel" to stop measurement.

Debug configuration for E2 or E2LITE emulator will have the selection of serial No. of the emulator and it can be selected from the list of emulators which are connected to the PC. But this feature will work only on Windows. In case of Linux, please connect only 1 emulator to the PC to use the emulator with e2 studio.
