Programming Problem: Extremely Frustrating

Plug in the OI via Tether.

Try downloading your code.

You have to have the OI and the RC connected to download the master code.

The problem is not going away. I tried installing new compiler and master code. But still it does not respond to any other downloaded program except "FRC_default.hex"
Its very frustrating...

For what it is worth, we have had a very similar problem. Compiling the code out of the box doesn't work. We spent a long time verifying all the hardware (FRC, serial ports, camera) was ok (it was).

We were able to get stripped down versions of the code to work, then slowly added back the missing pieces. Eventually it failed when we included enough code - even though that code was not being invoked. We verified that we are nowhere near the memory limit when this happened - we are using around 30% of available memory. We've checked all the settings in MPLAB - right processor, compiler and linker options, starting address to download and linker file. We've scoured the map file, to no avail.

Now we'll try the unistall/reinstall route - we've pretty much run out of other options.

Chantilly Team Here, it turned out we had done everything right, except for one problem, our computer was too old. It wasn't even a P1, so I guess it couldn't handle this years code with the camera in it. After struggling to get a new computer, the school finally gave us a windows xp laptop, P4 i think, and everything is working fine. Im not sure how old your computer is, but if it is somewhat old, or not the best computer, try reinstalling everything on a newer computer and working from there. Hope this helps.

Nothing like coming to the end of your rope to find the solution. We reinstalled MPLAB, the compiler and the loader, and everything works fine. Too bad we lost 10 days of programming time. On the other hand, we really understand a lot about the tools now!
