Thank you very much. The modification of the RegularExpressions.xml file works great and the error is gone.

At the risk of trying your patience, I have one more problem left. After checking the compiler, VisualGDB runs “Detecting conditional settings” and returns with a System.ArgumentNullException. I guess it’s because the ROM and RAM sizes of all detected Renesas devices are set to zero.
I’m not sure if this is important, but if I select a Renesas device it shows the correct file path to the device folder under “Shared file locations” in the bottom of the window (in my case it’s C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.1\rl78\config\devices\RL78 – G13).
I checked that folder and it seems like the .menu files are all there.

Is there some way to specify the ROM and RAM sizes of a device manualy ?

Thanks for the fast replay. Here is some testing I have done with your proposed solution:

I have added a new <ToolchainLoader> element (i copied the one from the IAR-ARM toolchain) and changed the <PathDetectionKey> to the Embedded Workbench for Renesas. I also changed the compiler, linker and assembler as well as the <BinaryDirectory> and the <IncludeDirectories>. As far as I can see, there shouldn’t be anything left which points to something ARM related.

If I create a new Project with the Embedded Project Wizard, the Embedd Workbench 8.1 (it’s the one for Renesas) is indeed recognized and can be selected in the dropdown menu. The Microcontroller type can also be selected in the “supported device” list below.

A problem occurs if I click “Next”. VisualGDB trys to test the compiler and returns with an error message: “Failed to launch iccrl78.exe. VisualGDB has tried to test your settings by building a simple project and encountered following errors:”:

Run “C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.1\rl78\bin\iccrl78.exe ” in directory “” on local computer

That is the normal output if you call iccrl78.exe with no arguments from the console. Could it be that VisaulGDB starts the iccrl78 compiler with no, or wrong arguments ? I have looked for a file which defines the compiler arguments used by VisualGDB but I couldn’t find one.

Besides that I am curious if VisualGDB’s Intellisense would still work with the code for the Renesas IAR compiler ?

 

If there are any ideas/solutions to the above problem you can let me know, if not it seems like I’m stuck with ARM devices 🙂
