2019 M3 lr sw: 2026.8.6 Flipper will not even identify the HW

[sqladm1n]

Hi.

Help needed, desperate. Flipper with the Electronic Cats Canbus 1.2 and original cable, will not identify the car at all, hang at Starting. OBD works fine with OBDLink MX and XBB and also with a Can analyser I found for the Flipper platform. TeslaMods Autotest gives up quite fast. Tried with turning 5v on the GPIO, no change. Was running on a dev release of the Flipper os, downgraded now to GA sw, with this 1.4.3 teslaMod crashes when selecting HW3 "NULL pointer dereference". What else can I try?

Update: Unleashed firmware latest, same result, Flipper crashes

Cheers
Marko

the same here, I am not sure about I have correct connection from bus to OBD, because there are 3 different GND point on bus, which one need to use?

TeslaMods cant detect the HW and crashing if use force use., showing both "bus fail" and also "NULL pointer dereference"

Now on latest release. Sw will not autodetect HW3. Manually starts ok. Nag killer will not turn on, no matter which settings I use. I dont have FSD, only after nag killer for autosteer.
