Important Issue - Downloading with ROBOTC 2.00
We're getting reports of users running into issues with download programs to their robots. We're currently looking into these issues and working on a resolution/update for ROBOTC.
There is one primary known issue that we are working on, involving the "Compile and Download" command. The issue seems to be caused by ROBOTC incrementally downloading the program to the NXT and a memory issue on the PC-side where it is not recognizing changes in the program. We're close to a fix and an updated release - but in the mean time, try a suggested work around:
1. Open or modify your program inside of ROBOTC.
2. Save your program by going to "File - Save" (or use ctrl-S keyboard shortcut)
3. Go to "Robot - Recompile Program" (or the F7 keyboard shortcut) - This step forces ROBOTC to regenerate the code from scratch.
4. Now go to "Robot - Compile and Download" (or the F5 keyboard shortcut) to download your program to the NXT.
5. Repeat these steps whenever you make modifications to your code.
If you're experiencing other issues, please submit a ticket with details of the issue you are experiencing. Thanks!
