Macchina A0 suddenly not working with ESP32RET

Open Ldalvik opened this issue 11 months ago • 10 comments

I have been using ESP32RET and SavvyCAN for the past few days with no issues. Then, I believe I updated my ESP32 board libraries. After testing multiple versions, (2.0.0, 2.0.17, 3.0.0, etc) I reduced it down to v3.0.0 getting me farthest. Other versions will throw weird errors like "spin lock assert" crashes.

With ESP32 board library 3.0.0, the serial output is

"Loading settings... Running on Macchina AO TWAI driver installed Creating queues Starting can handler task"

And it stops there, LED staying red. I have been reverse engineering my CAN bus all week and the code still works to read RPM, current gear, etc. so it is not an issue with my CAN bus. I just cannot get ESP32RET to work anymore. Even after flashing the ESP32RET.bin, it says the board is an EVTV or something. Any help would be appreciated, as I feel like I've tried everything.
