_entry_scn error on building

[Roger]

I’m sorry this is taking so long. I thought with the //FILES c018i.o I was free and clear!

Both the MPLAB and IFIloader are from last year’s kit. We’ve loaded this year's disk on other computers, but at the time we only had last years set and ready. Also, the robot code is last years, and we’ve been loading it onto last year’s robot.

Right now I’m not with the computer nor robot, but I have my own computer with duplicates of everything. It also tested the code and compiled successfully, just to see if a different computer can do it.

Here is the output from the last successful build:

(I’ve snipped out the exciting middle 1000 lines.) I’m assuming the beginning numbers on each line are some hexadecimal address, except yours stays low, but mine jumps up to the 1000’s at the 3rd line.

Build Options – General:

Include Path: C:\mcc18\h
Library Path: C:\mcc18\lib
(all others blank)


Finally, I’ve attached a picture of the MCW list, and one of Build Options – MPLAB C18. -- Well, I would have, except it's not doing what I thought

Build Options, MPLAB c18 tab, Use Alternate Settings:

-mL -Ou- -Ot- Ob- -Op- -Or- -Od- -Ooa- -nw=2066 -D_FRC_BOARD

mcw ~ mcp list: Along with all the C and H files, FRC_library_8722.lib and 18f8722.lkr.

One final thing. I took Kevin.org's frc_camera_21.zip files and compiled them successfully, straight out of the box, butgot the same error with IFIloader. The HEX file supplied successfully downloaded.

Hopefully this is enough for you. If I have to I can get to the school tonight for more, but I’ll be there tomorrow for sure. The internet is a little flaky there, so it’s a choice of being next to the robot or on the internet. Thanks again for your help!

Roger.
