Hi, I have a Discovery Lite and Trig TT22 Remote transponder with MGL Trig interface connector that connects the TT22 to the EFIS via the CAN bus.
I have SP-6 Compass, TT22, RDAC Device and Discovery on the same CAN Bus.
It all was working fine for a while (over a year and 70 hours), but recently the Discovery gets into a mode when it starts to crash loop - crash, restart, crash again, restart and so on.
I collected the CRASH.DAT file - i put here (can't attach it to the post, it says invalid extension):
https://www.dropbox.com/scl/fo/um8ts7wq ... 3sejg&dl=0
I isolated this crash to to be related to the TT22 - i wired an extra switch to keep the TT22 off and when it's off all works well, all works well, but living where I am (in the Mode-C veil of KSFO), i can't fly without a transponder and ADSB.
I updated the EIFIS firmware, but that did not really help. Any help would be appreciated.
Is there a viewer for the CRASH.DAT file that could give a hint?

Re: Discovery Lite crash looping
I've disconnect the wiring harness that I got from the kit manufacturer (RotorWay) that connected all the CAN bus devices and fabricated my own CAN Bus using n Carlisle Can24Tst120 Can Bus Cable. I terminated the shields to the ground with the shields connected on one end only (similar to MGL V16 radio wiring guidance).
The crashes stopped. Looks like problem is solved.
