Indeed, maybe even enough pins left on the "slave" (whats the new word for this?) STM32 to have it handle the buck/boost

I tend to use primary and secondary. Or maybe main and ancillary.
The software can recognize MG1 and MG2Abricosvw wrote: ↑Tue Mar 09, 2021 3:00 am hi
i am trying to setup the second motor (MG1 out put) resolver is not connected yet
motor generator gm eAssist hybrid

as I understand it, the software should recognize itself MG1,MG2 ...
but I have ( hwver REV2 ) in MG1 maybe that's why everything conflicts and does not want to work ???
the settings of CANl bus do not want to be saved
I will be grateful for any advice or direction!!!
thanks
I've found the problem. It was two resistors R141 and R146 at the output that were 10K instead of 10 ohm. Especially they were at the output it was the last place for me to look.

I'm seeing an issue where my main contactor is not closing. I have UDCSW set to zero. The precharge contactor closes. No errors in the web interface. It seems like the inverter thinks it's closing the main contactor.
The main contactor definitely works. If I manually ground it, it closes OK.
Tracing back from the precharge and main contactor lines, I see there are two test pads near the MG2 STM32F for these. I'm seeing 3.5V on the precharge line OK, but only 0.2V on the main contactor line. Could I have a bad STM32F? Is there something else I should test?

Hey @zillion, thanks for the suggestions.
How are you starting the inverter? Are you using the start input or manual mode?
