Updating Jaguar Firmware for CAN
We are trying to configure our Jaguars for CAN, and are following the instructions on page 17 of this document:
http://content.vexrobotics.com/docs/...artedGuide.pdf However, we are stuck on Step 4, as the Board ID dropdown menu is greyed out even after we went through step 3 successfully with all of our Jaguars blinking green during ID assignment and then blinking yellow with their ID numbers. Any help would be greatly appreciated! ![]() |

Re: Updating Jaguar Firmware for CAN
I have the same problem. I also have a blinking yellow light. Instead, however, BDC-COMM is connected to COM Port 4 but it did not connect automatically I had to select "4" from the drop down box (I'm using a USB to serial cable). Also, there is a "Trusted" icon in the top left corner of the window. Otherwise, everything it the same, all grayed out and no board information. I tried resetting the jag while assigning a new board ID but even after the countdown the board information isn't any different. I would really appreciate any help, been struggling with this for a couple days.Thanks!

Re: Updating Jaguar Firmware for CAN
With BDC-COMM-107 I'm getting a "COMM FAULT" and "Can't contact bootloader" error when I try to update firmware (black-jag 107).
Just for the heck of it, I also tried older versions of BDC-COMM. With BDC- COMM-101, before I could even try to update firmware, I got a "Could not connect to specified COM port" error (no matter which usb port I try). With BDC-COMM-99, I get the same reaction as with BDC-COMM-107. At least the USB to serial cable has more relable/replicable results. With the RJ-12 cable I couldn't even get BDC-COMM to give me the "Trusted" label in the top left corner of the window. |

Re: Updating Jaguar Firmware for CAN
This usually means the serial port is in use by another application. Are you sure you didn't accidently leave BDC-COMM107 running while you were trying to use this one or something?

Re: Updating Jaguar Firmware for CAN
I fixed the problem with not being able to connect with the COM port by trying a couple different laptops. The serial to CAnN cable came with the kit of parts and the USB to serial cable was ordered off amazon. This is the product: http://plugable.com/products/pl2303-db9. Yes we're using a CAN terminator we made it using instructions made by Team 1718 online. We're using a single black jag right now. I haven't tried connecting to multiple jags yet and I figured I would try the black jags before working on the old tan ones. This is what the BDC-COMM screen looks like right now. Thanks!

Re: Updating Jaguar Firmware for CAN
Solved this problem on my end, electrical has just informed me they did the cabling wrong.
Always makes you feel a little better when it's not your fault ![]() |

Re: Updating Jaguar Firmware for CAN
CosmicCricket, can I ask you what you did to solve the problem on your end. How did you get rid of your blinky yellow lights?

Re: Updating Jaguar Firmware for CAN
After you assign an ID, the lights should blink a certain number of times depending on your ID. If it's happening beforehand, you should look at your cabling.
Our cable actually tested fine on a voltmeter, but we found out that whenever we pushed it into a port one of the wires would end up slightly out of place, which messed the entire thing up. |
