Re: BlackJaguar-99.bin issues
 

I just flashed a 2012 Black Jag with version 100 bin. It took two attempts however. The first time I tried, the 2CAN status LED was RED indication an issue on the CAN side. The web dash confirmed this. Attempting to flash the jag resulted in failure (as expected) and the web dash indicated "no ack received" After power cycling the JAG only, the status LED turned orange, the Jag appeared in the web dash and version 100 was successfully uploaded.

You may have already tried this, power cycle the jag and re-attempt the flash.

Re: BlackJaguar-99.bin issues
 

I have flashed version 99 several times and never experienced this issue. I will try to reproduce it when I get home.

Re: BlackJaguar-99.bin issues
 

Ok, so tried to a tan/gray jaguar now daisy chained to one of the blacks. It was running 92 and tried to update to 100 it failed. I recovered it back to 92.

I am using a usb to serial adapter, but since I was able to do it to 92 and I can use adjust the controller with bdc-comm, I am assuming that is not an issue.

Thanks for everyone's help I appreciate it.

Our jaguars also stopped blinking when I tried to update the 99 firmware. I wasn't able to recover to 92, 99, or 100 using their respective bdc-comm exe's. Finally, I tried recovering it on another computer (the classmate) and that worked. (I happened to recover the the v100).

Re: BlackJaguar-99.bin issues
 

Check your cabling and termination resistors, if the cable loses connection at all during the bootloading process the Jaguar will remain in bootloader appearing "bricked". If you are not confidant in your cables several companies sell CAN cables already assembled. Also make sure your termination resistor is secure and properly connected. If you are using a 2CAN use the web dash features and the LED state to ensure you have good CAN connectivity.

Re: BlackJaguar-99.bin issues
 

I finally switched to a third computer with a built in com port and was able to successfully upload v100. The cause of our issue seems to have been the usb to serial adapter. Unfortunately at this point I am only having trouble communicating with one of the gray jaguars that was corrupted in all this.

Re: BlackJaguar-99.bin issues
 

This question isn't exactly related to the previous comments, but does anyone know if the Jaguars that shipped in the KOP are already running the FRC2012 firmware? We only need one that has the automatic ramp feature and I'm hoping that it's already built in. From TI's FAQ:

Q5 Which Jaguars have the Automatic Ramp mode?
A Jaguars purchased or received during or after the 2012 season contain the Automatic Ramp mode in the
factory default firmware. Older Jaguars can be updated to the latest firmware. See the Jaguar Getting Started Guide for more information.

I think I'm just splitting hairs on semantics here but I would really like to verify this first, as we will not have a electrical board that can power up to do a POST anytime soon.

I am aware that we can update the firmware on older jaguars and/or can perform the same operation in software, just was hoping that it was already built into the ones we received already.

Re: BlackJaguar-99.bin issues
 

If by Automatic Ramp you mean a voltage ramp, the firmware has always supported this for use with CAN. If you wish to leverage this feature over PWM I am not aware of a version of the firmware that supports this. If you are using CAN you should update to the latest version of firmware.

Re: BlackJaguar-99.bin issues
 

If they came in the kit, they are not FIRST firmware, but they have the ramp mode. The Jaguar document should be pretty clear about this.

Re: BlackJaguar-99.bin issues
 

The latest released non-FIRST version supports this on PWM mode by rotating the limit switch jumpers 90 degrees. So does FIRST version >= 99. See the Jaguar document on FIRST's website.

Re: BlackJaguar-99.bin issues
 

Ah it's in the FAQ, something I do not read anymore, TI should probably put this in the user manual under jumper configurations.

Re: BlackJaguar-99.bin issues
 

I would like to encourage teams to read the 2012 Jaguar FAQ because it contains lots of useful information and can save lots of time when debugging simple issues.

In addition to the FAQ, the Jaguar Getting Started Guide has even more information, including info on the Automatic Ramp Mode (in the Operating Modes section, page 11).

Both of these documents are found at www.ti.com/jaguar.

Re: BlackJaguar-99.bin issues
 

Mike - We were a Beta Testing team this year and the Jaguars we were Beta Testing had this enabled for PWM. I should have stated this in my original comment. Thanks for the info!

Re: BlackJaguar-99.bin issues
 

Mike and Joe,

I think one of you has a problem. We tested the V93 firmware just prior to RiverRage and ran into a problem of not being able to flash the new firmware. I had the same issues with the V100 firmware. *None* of my Jags could be flashed. The 2CAN reported a timeout error for each.

We tried having a CAN bus with just 1 gray/tan Jag. Tried switching terminator resistors. None of that helped.

However, we easily re-flashed the V92 firmware. Fortunately, I found the post that said it was in Public Documents\FRC on my computer. It's not searchable on the TI website.

Any suggestions on what to try next? Would using the BDC-COMM app over a USB to serial connection help? Might we need an upgrade to the 2CAN firmware?
