Actually, I soldered regular board and wired ESP-M2 8285 module - and it worked better. This time upload script did the job properly, so I had no problems with filesystem. But 8285/8266 is very different from ESP32 in terms of filesystem approach and memory handling anyway. 1,5 years ago I also had ...

Action time~!

Pretty wonky, yes. But as i said, in my case other ways failed for some reason.
For example, when I flash FW directly from Arduino IDE - i get problems with partitioning and have mounting errors in debug.
It seems that even if I try to flash everything from it - it ends up uploading only compiled ...

Ok, made ESP32 firmware roll.
Here's my step-by-step guide. I use win10 64bit LTSC.
I downloaded:
- sketch from jsphuebner's repo
https://github.com/jsphuebner/esp32-web-interface
- mkspiffs - win64 for esp32, v0.2.3
https://github.com/igrr/mkspiffs/releases/tag/0.2.3
- esptool - v4.10.0 for ...

I decided to try Tesla SDU board. I can't order directly, so I generated gerbers and ordered boards, then soldered them. Decided to make V8 or V9 with ESP32. The difference between V8 and V9 is not so big, so used V9 for the sake of freshness. Soldered all components, and now I'm ready to flash.
So ...

It was TDA. Now we have some spin. Time to tinker with resolver offset.

UPD. Got some decent RPMs and almost found good syncofs . But half-baked IGBTs finally decided to die. RIP.
Will wait for new inverter now. While it's been delivered I will apply some fixes to my logic board, also rework wires ...

Ok. First, some problems with current sensors were solved. Now it calibrates just fine. Also, there were some strange shenanigans with protection circuit comparator and input/output logic. Also solved. Second, I found cross-layer short-circuit on IGBT board and restored and replaced everything ...

johu, thx, will check input dividers tomorrow.
A bit confusing. We have 3k3+4k7 on mainboardv3.4.pdf from git, only 3k3 for v2 board wiki (https://openinverter.org/wiki/images/a/a1/Schematic_main_v2.png), mainboard_mini has 3k3+6k8 as you suggested and as far as I can remember, mine is 3k3+10k which ...

Ok, we have an issue with both current sensors.
They show around ~2,45 volts on outputs with zero current - hapf supply voltage or so.
It's too much, should be between 1,23 and 2,06 vots. So we have permanent HICUROFS1/2 and OVERCURRENT stop.
Is it possible that our sensors are damaged?
Which ...

Ok, we're definitely alive here. At least WIFI web-interface yields legit errors and numbers. Overall it consumes like 500-600 mAmps from 12V psu. Gonna test with engine and HV supply on upcoming Monday-Tuesday... Wish me luck! =)

Well... Should be something like this.
Please correct me if I'm wrong here.

johu, thank you. But I asked about IGBT Drivers Board pinouts. Not about OpenInverter board.
As i said, I don't have stock cables. I can tell where all six PWM signals go, but I'm not sure about FAULT1, FAULT2, UDC_PWM, heatsink temp and both current sensors.
I'm talking about this board and sockets ...

Good day everyone.
Right now I'm working on Leaf-related project - my friends are building custom electro-bike using Leaf powertrain. And I'm making inverter control board for them. We have good engine, 90%-probability-good driver board, battery assembly (now balancing) and toasted inverter logic ...
