BlackJaguar-99.bin issues

[Mike Copioli]

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.

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

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).

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.

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.

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.

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.

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.

We do not own one.

Is there a limit to the number of jaguars allowed?
I've looked through the manual several times, just cant find it. Even a page number where i could look it up at?

There isn't a limit, but the Jags all have to have unique device numbers. Having fewer devices simplifies things if you are having problems. When I update (on a known working setup) I have 12 or 13 Jags on the bus.

There's a cable length limitation which I believe is 20' for the CAN bus. You should also have a terminator at the last Jag. You can have about 62 Jags since the IDs for the Jags are 5-bit (64 values) and you shouldn't label any of them 0 or 1.

This is not the case. See the below post.

Just quoting specs.
