I recently got the Tesla model 3 PCS and the board sold by Damien. I wired everything up and got to testing I was able to connect to the wifi network but then once navigating to 192.168.4.1 I see no parameters and I also see SWD error whenever I try to upload files. I am assuming the esp board isnt communicating with the STM32 board ?? but not too sure. Anyone have any ideas on what could be wrong or thoughts on where I should start to fix this. Any help would be greatly appreciated thank you

Why are you trying to upload files? Board is supplied programmed. Also swd upload is non functional.

Yea I was wondering if for some reason it hadn’t been shipped already programmed. I actually ended up using an st-link to program the board but that didn’t help either as the board indeed comes programmed. Just trying things because I’m not sure where my issue is

If the running LED does not blink the STM32 has not entered run mode. You might have messed up the programming by trying to reprogram it.

It behaved the same prior to trying to program it. What should my next step be

What did you assemble.
When powering it on only providing it ground and 12V Permanent does the Power Led light?
If the Power Led Lights but the ACTTY Led does not light the STM32 is not going into the main programme for a some reason.
I note you wired all the wires just willy nilly without using a connector. This looks very sketchy and is a very easy way to create issues and damage things.

Yes when supplying just 12v and ground the power light stays on but actty led does not light. Any ideas on what I could try or test to further figure out the issue? I’m just stuck here

Just to confirm, did you disconnect from the PCS for this test? Also, you might try removing the wifi board and PCS and booting with 12V (only 2 wires connected to the board), I believe you would see the activity LED blink if the STM32 is booting correctly. This would isolate the board from any potential external stimulus.
