"Cannot communicate with robot controller CPU"

Post by johntimber » Tue 12 Jun 2018, 09:09

Hello,

I've now tried a Uno, Mega, Duemilanove and all fail the same way with RobotC for Arduino 3.54. Although I can download load the RobotC firmware fine, when I try to compile and uploade code I almost always get this error: "Failed to verify that he serial link is connected to a Robot Controller.
Cannot commnicate with robot controller CPU" I did get it to work once with a Uno, but none of the variables were showing up in the debugger. And I've never got it to work again. I've tried on two PCs, both Windows 7, 64-bit. What am I doing wrong?

Please help

I didn't find the right solution from the internet.
