The Code error light on the OI only lights up for two major events, if you indeed have a code error within you code OR you are in program state.

Now, if you upload your code AND the light remains orange, it means that the code was incomplete. I got this error alot last year, our USB to RS-232 (Serial) adapter was loose and the cable was not connected properly.

Also be sure you have the most updated version of the IFI Loader. (If you installed the programs from the discs included in this years KOP, then you do.) We were had problems until we noticed that we had an outdated version of the uploader.

One more thing to check is the computer you are using. I have notice that certian computers encounter problems when trying to download; they either detect the connection wrong or will stop uploading part way through. This happened with one of our team's coach's laptop.

Now, I am fairly sure that you CAN upload the code to the robot when no OI is connected. I know that the User Processor requires the OI to be connected.

I dont see how you HAVE to use EasyC to upload EasyC files, a HEX file is a HEX file.

Have you tried connecting the computer to the dashboard port on the OI and using the Dashboard program on IFI's website? It gives you error codes and reasons for the Error Light.
