Ok so I tested several configurations and can't seem to find the issue, though I did have some interesting settings issues.
First, in all cases the error message from the Electrify America charger was 23_00H_0 This occurred after the station appeared to begin delivering power. Watching on the web interface, it appears the station does all of its checks (station side voltage rises, drops to zero, the rises back to the car's voltage), and I hear the contactors close in the car and the station, but then it throws the "Malfunction|Stop" error message in the web interface and the station says charging failed.
I've just set up the stm32 chademo controller in my car over the weekend, I tried to charge on a tritium Veefil charger and got through to the same point as you. The charger says status code 13, which appears to be the vehicle not requesting a charge current.
I've not had time to look too closely but I'll try get a CAN log in the next day or two
I ended up rebuilding my entire HV junction box to put the shunt in the correct orientation to rule out that as an issue. Unfortunately, I broke an axle in the car back in February/March and am just now getting to the point I can afford to repair that and get back to fixing Chademo, so I don't have any more info yet,
If at first you don't succeed, buy a bigger hammer.

It will be good to see it moving again! I was hoping to take my car to try a different station and get a can log but it was out of order. When I got back I powered up the chademo controller and hooked up my wall charger just to confirm correct idc reading. That all looked pretty good to me.. One thing that caught my eye was the charcurlim value was at 0A I have the charge limit set at 30A for now, but I'm not sure if that value is for vehicle side or the chargers current limit.
I took a quick CAN log today, unfortunately the software i'm using won't convert to an easily readable file. Here is a screenshot from after the isolation test and the contactors were closed. I need to read up on chademo protocol, but it seems like the controller isn't sending any current request.
I have found a hardware fault, fitted to the board is a bsp75n low side driver and on the schematic is a ncv8402. The difference is the bsp75n has the source on the tab and the ncv8402 has the drain on the tab. I wondered why the the HV enable pin was earthed the all the time .

Still having Chademo issues, I've managed a couple of sessions, but more often than not I get failures.
I hear the lock in the connector click, then my chademo contactors click closed, then they open again after 5 seconds or so.
Any pointers?
EVSE:fault code 27 Abort, then EVSE:fault code 26 Abort. then EVSE:fault code 22 Abort.

The same happened to me couple of posts back. I solved that by first changing ISA direction (simply turned it over) and later i reprogrammed it via CAN to show negative current when charging. It seems it works on all but one ultra fast EVSE.

The EVSE never reports any current flow, Im not sure that's the issue, but can give it a go. I'm wondering if I've got a dodgy pin in the inlet.
*EDIT* My shunt already reports positive for discharging and negative for charging.
Not so easy... i tried the same and failed. Out of desparation i reversed the shunt physicaly. It worked! Then i went to reprogram ISA shunt so i could have good mounting for the shunt. Correct orientation is what solved it for me.
Yes, there was still the case of explicetly declaring CAN msg as not extended! That did also help.
It's strange, the station matches my voltage then just goes right up after requesting a small amount of current. Sort of like the conactors have opened.
Rolled back to a known working version and I've managed to charge at the BP unit again.
I've come across an InstaVolt that seems to do things in an odd way, it grounds pin 10 first and then gives 12v to pin 2 and the code seems to start ramping current requests too early. Charge fails. Extract of log below and full log attached. I'll see if I can modify the code to work, after a few more successes on the BP to prove it wasn't a fluke.
If I'm not mistaken it's your code I'm running, but slightly modified to send out a can message to my car to close main contactors, but not sure what that's about.
I'll grab another log incase of funkyness.

Is anyone still producing a CHAdeMO controller board? I can’t find anything on Damien’s webshop.
Yes, I do. Been in presale for a while now so you need a code for checkout. https://www.evcreate.nl/shop/charging/c ... ontroller/
Send me an email if you are interested and I’ll share one.
It’s installed in quite some cars now so I’ll remove the code restriction soon.
No, have never seen those, also not during trips in Germany, Sweden and Norway.
One thing you might need to double check is if the code logic matches the hardware in terms of IN1 and IN2. Depending on weather optocouplers are used or not the signal might be inverted. Can’t remember the exact details and probably is not the root cause since then probably it would not have worked at all but still worth checking.
Yea, checked and double checked these, Start 1 is connected to IN1 active high, and Start 2 is connected to IN2 active low. Will get more logs and try investigate what's going on.

Charging worked again on other units, but the Instavolts still refusing to go, same deal, they switch IN2 first, that doesn't prevent it carrying on to closing the contactors but current doesn't seem to flow despite requesting so.
