Re: Problem with program uploading

I am having the exact same problem, although I am using the IFILoader.

Information about problem:

Without the OI connected to RC, the RC has green lights (except for radio modem (red), and RC mode (no light))...in this state I can hold the programming button down and get the RC into programming state. I do a controller verification, which is successful. Now I try to load the code and IFILoader tells me that the Controller is not connected to my computer or the RC isn’t in programming state.

With the OI connected to the RC, the programming state is orange (without me making it orange), the RC mode is orange, and the rest are green. In this state controller verification is also successful, but when attempting to load the code, we get an error message saying that the RC is not connected to the computer or the RC isn’t in programming state.

I'm using a DELL laptop which has a serial port (device manager tells me its @ COM1). I've tried multiple serial cables to ensure that the cable is not faulty. I also tried loading the firmware again, but IFILoader tells me that the RC is not connected to the computer.

IMPORTANT NOTES:

If I open the Terminal Window and turn the RC on I get scrambled text (general 2 or 3 letters). Sometimes I comes as "IFI>" which I what I thought it as supposed to say, but most often it just has 2 or 3 random letters. (If I press reset or programming buttons, the Terminal window shows another 2 or 3 random letters.

This laptop and RC were working just fine yesterday…I was loading code without any problems.

My guess is that something is wrong with the RC.

If anyone has any suggestions, please post them...you have no idea how frustrating this is getting. Many thanks!! - Jay (Team 610 Programmer)

-----------UPDATE----------

Using the same laptop, same serial cable and same software I was able to load code onto an EDU controller with no problem. I noticed that it displayed PIC18F8520 as the version. However, when I connect to the 2007 RC it shows "FRC" as the version. Shouldn't it be showing PIC18F8722?

I have also tried everything using the EasyC loader, and I got the same results....
