Problem with Black Jaguars, unable to update, stopped blinking

[Mike Copioli]

Ok,

There was a bug in the 2CAN Jaguar firmware update utility that caused the firmware attempt to fail on the first attempt. This bug has been fixed in the latest 2CAN firmware found here http://www.crosstheroadelectronics.c...2_24_FIRST.zip. However this is not the only thing going on here. When the Jaguar firmware upload attempt fails the recommended procedure is to power cycle the Jaguar just in case the Can controller is in the Bus off state. While this fixes the bus off state it causes the Jaguars CAN bitrate to change to 500 Kbps. This is why neither the 2CAN or BDC comm is able to update firmware over CAN. There are two ways you can remedy this;

1. Use BDC comm over serial to update the firmware.
2. Change the 2CAN's bit rate to 500 Kbs under the 'CAN configuration' tab in the web dash.

If using Method 2, make sure you change the bitrate back to 1Mbps after you have successfully updated the Jag firmware. You can also verify that the bitrate has changed at the bottom of the 'Main' tab of the web dash as well by verifying that the 'CAN Bus Status' is showing no Error counts after setting the 2CAN bitrate to 500.
