I am working with RL78/G14 fast prototyping board and e2 studio. I'm trying to make a ledblink example to learn the IDE. However, in debug mode I get the error "GDB action 'connect to target', has failed with error code, 0xffffffff".Also, ackled does not light.
Debug hardware: E2 LiteToolchain: GCC for Renesas RL78 (18.104.22.168201)
Is there a solution you can suggest for this problem?
Thank you for your help.
Check out the User Manual. There is also a video for setting up tools FPB Video.
Section 7.1 shows you how to connect to the board, using the built-in emulator - E2 Lite.
Thanks for your answer. However, I have progressed by following these steps.
I followed the steps at this address.
The board does not appear in device manager. For this reason, I thought it might be a driver problem, but I could not get any results from there.
Did you check if the emulator reset header was shorted? That's one possible cause why the E2 Lite like emulator of the G14 FPB doesn't appear in the device manager.

Thank you for your returning.
I checked, it is not shorted.
Oh it seems like you've shorted pin 2 and 3 of the power supply selection header. Did you also cut the SS11 pattern?
Yes, I cut the ss11 path to get 5V supply.
In that case, you should be able to upload the code to your board unless you received a faulty board and the only way to know that is to get another board and test it. But I also get this kind of error when I accidentally stop the debugging process while the IDE is still uploading the code to the board. However, once I unplug the board and restart the computer, the error disappears. Have you tried that?
Now I restarted the computer and tried, but still no result. I'll try it after I get another board. I will share the result here. Thank you for your quick replies.
If you receive the new board, don't modify it yet. Just test it immediately under 3.3V operating voltage. That way you'll be sure that the error is not due to the modification of the board. Also, try to check your board again if you have properly cut SS11. Try to use it too on other computers.
