Problems using the easyC Loader

Though rare, the Vex Micro Controller can be unintentionally locked into a Master Download State, usually indicated by a solid green PGRM Status light. This problem is corrected by replacing the master code on the micro controller. In this state, you will be unable to download and execute normal programs through easyC. Users downloading with the USB to Serial Adapter may also be unable to replace the master code to reset the Micro Controller.

This issue has been addressed and a new version of the IFI/intelitek Loader capable of replacing master code with the USB cable is available from intelitek. To download the update for the Loader, go to Download the file and follow the instructions in the included text file. If you have any questions, please email intelitek at [email protected].
