Position Control using potentiometer?

It seems that the V87 update has bricked one of our jaguars, is there any info on how to upload a previous firmware, or a reset to factory software?

The jaguar does not blink any lights, and does not respond to either PWM, or CAN enumerate.

This can happen if you loaded (Gray) Jaguar code on a Black Jaguar and vice versa.

Firmware for Black Jaguar is "BlackJaguar-87.bin" and the firmware for (Gray) Jaguar is "Jaguar-87.bin".

There is a way to recover by using BDC-COMM in the command line.

Open up a command line terminal and navigate to the folder where you have bdc-comm.exe. To make it easy you can put it in your 'c' drive. I also recommend putting the firmware files in the same folder as bdc-comm.exe so that you do not have to type in a file path.

In the command line run the following:

1)
C:>bdc-comm.exe -c N

- replace the 'N' with the COM port number you are using

2)
# id X

- replace 'X' with the ID you had previously set for that Jaguar (factory default is 1)

3)
# update BlackJaguar-87.bin

- if the firmware is in the same folder as bdc-comm.exe, this will work. Be sure to change the file name for Gray Jaguar firmware.

The update should happen, showing progress as a percentage. Hopefully if everything went OK your Jaguar should be blinking again.

The files seem to be miss named, the BlackJaguar-87.bin file worked on a grey Jaguar, but the Jaguar-87.bin file caused it to crash.
Thank you for the help, I will try the position control again tomorrow.

Doh! I'll let you know when this is fixed!

The files are correct now:

BlackJaguar-87.bin -> Black Jaguar MDL-BDC24 firmware
Jaguar-87.bin -> (Gray) Jaguar MDL_BDC firmware
