Thank you! Currently my parameters are: params.json
I now have snycofs at 10,000, and when field weakening was disabled the unloaded motor spun well in both directions, with the same resolver as provided the plots above.
I already had it mounted in my project, and installed the cv axles. I have a ...

I am now pretty sure that this is an issue with my syncof value, because when I change it the behavior changes. At syncof 12900 the motor spins smoothly in the forward direction, and yields good throttle Controll, but seems slow, and if I put it in the reverse direction it runs away immediately. I ...

It is spinning forward

Hello everyone,
I am currently testing my Gen 3 Prius inverter and transaxle with a V1d board from EVBMW. I’ve got them hooked up to a HVJB and I am currently testing with a 80v battery. I am trying to get my throttle working to spin MG2, but keep running into the issue of the motor “running away ...

Eons later I have returned to this problem and solved it. I did Damien’s resolver test he outlines in his FOC tuning video, and I also realized that I had a value of 10500 for syncoffs, which was good enough to keep my motor from spinning.

Hello everyone,
I am looking to see if anyone is interested in building out/programming an V1d board for me for paid support. I have a conversion project that is mostly put together, but have hit the snag of struggling with my inverter board, even with the generous help of people on this forum. I ...

I am not sure…
Mine has less markings on the AC connector than it did on the DC one, just says “DELPHI”
But I have not spent much time looking for it yet.

I have found that this connector works for the HV DC output on the charger: https://www.digikey.com/en/products/det ... -1/5423199
and this one for the control pins: https://www.digikey.com/en/products/det ... 01/1756779

Thank you both! unfortunately I've been away from my testing set up, but will be back Tuesday and will be making updates to my parameters/troubleshooting per your advice, and getting new resolver plots.

Hello everyone,
I have recently been trying to get MG2 spinning on my Prius transaxle, but have not been successful for awhile and could use some help. I have a gen 3 prius inverter and transaxle, and am currently trying to get MG2 to spin.
I was able to get it spinning with an open loop test ...

Ah Shoot, dumb mistake! I was looking at the pinout description on the gen3 board wiki, forgot about the separate schematic for the dual motor boards. Thank you!

Hello everyone,
I am doing a conversion with a Gen 3 Prius Inverter and gearbox, and will be using both MG1 and MG2. I have already welded the PSD, and have the dual motor (V1d) board from EVBMW. Looking at the pinout for the idc connector for the bord, I can only see connections for one resolver ...

Success!
With the the ST-Link Reset Mode Settings set to "Software System Reset", and Program and Verify in "Validate After Programming" mode, the Version 4 bootloader and "stm32_foc_DetectInvlaidSizeFFFF.hex" code you sent worked! :D Now both LEDs are blinking, and in the wed interface for each ...

I have been using ST-Link since I was having trouble with the cube programmer earlier. It returned 0xff not 0xffff.
For now I would like to try and make these chips work. Pretty much all of my soldering experience is installing the connectors on this board and some parts of the power stage that ...

Certainly progress :)
When I use your readback to program in "validate after programming" mode, I don't receive any errors, just this:
"00:11:39 : [readback_full.hex] opened successfully.
00:11:39 : [readback_full.hex] checksum : 0x017F2718
00:11:54 : Memory programmed in 11s and 359ms.
00:11:54 ...

With my verification setting changed to "validate after programming" and the solder ball removed (there don't appear to be any others on the board) The "stm32_foc_StandaloneTestApp.hex" program worked properly and was able to get MG1's and MG2's LEDs to flash. Programming the STMs with the ...

I’m looking forward to tying the program

Yes, I am in the US (western coast), but I appreciate your offer. I think I am going to pick up one made by adafruit on digi-key
https://www.digikey.com/en/products/det ... 48/6827110

Thank you for doing that!
Yes I will do all of those, I am going to try and find a genuine ST-Link as well. I will not be able to work on it until Wednesday, but I will send updates then.

I have been using the latest bootloader from here: https://github.com/jsphuebner/tumanako-inverter-fw-bootloader/releases
I just tried using the Version 4 bootloader from the same source, but with no luck.
On MG1 (where I know that I once had a blinking LED) I tried loading the bootloader, doing a ...

I was able to get that excess flux off of the board, and I renamed each ESP network so that they can be identified (I can now connect to either while both ESPs are installed).
I just replaced the MAX735CSA+ on IC17, now I get a consistent -5V and it is not heating up a lot like the old one did ...

Sorry for the delay since last post. I've spent some time working with it and here is what has happened:
wifi modules: both appear to be receiving the necessary power supply, and I can connect to both individually (i.e. only one on the board at a time). When both are on the board, I still only ...

It looks like I need to add power to the ESP modules from a capacitor, this may be why I am only getting one network. After this weekend I will be back home with a 12v supply again and will test both modules.
Here are photos of MG2 chip, MG1 chip, and info from the ST link:

Thank you guys a lot for the detailed responses.
It turns out that I am getting the wifi that I am supposed to. I knew that the modules put out wifi called "inverter" with a password of "inverter123" but in the wiki it says there should be a wifi titled "ESP-..." which is why I thought that I was ...

I just tried that, it did not solve the issue
