How to reset the Zombieverter

[Scrappyjoe]

Hello. I have tried searching, but am not getting an answer so I thought I'd create a new topic.

I have received a secondhand ZombieVerter from a builder on this forum. When I attach 12v and ground, I see the Zombie's (customised) SSID come up on my WiFi list. So I know _something_ is happening. But when I try connect, I am unsuccessful. Seller has forgotten the password, and my guesses aren't working.

So. Question:

How do I reset the ZombieVerter to 'factory' (ha ha) settings?

The way I see it, either the answer will be

a. 'there is a button you press with a paperclip' or,
b. 'buy an STLink cable, download {insert stl computer app here}, connect to Zombie from laptop with cable, download latest Zombie release file from {insert release page here}, upload to board {via insert method here}.

But I don't know which of these two the right answer is

Scout's honour, I'll update the wiki once I succeed

The password is on the ESP wifi module so no point in "resetting" the main controller
You could fit a new one or search the web on how to erase the flash that stores the password

Aha! Well, that makes things simpler for sure.

I've pulled the module off of the board - the model name is MOD-WiFi-ESP8266 Rev B. That is, it is commonly referred to as an Olimex board on this forum.

A little bit of digging, and I have come to the conclusion that I need to re flash this board with the software it originally would have shipped with from EVBMW - which is this software (which, I note, you wrote johu ) :

A little bit down the README we have good instructions for reflashing via a wired method

So I will head off and buy a serial to USB adapter now.

Cross reference - the Olimex module has a wiki page here.

I've added a bit of info there to make it a bit clearer what it does.

I didn't see an answer to the subject question. Is it as simple as powering down the VCU? I would like to know, since Ver 2.05 has a note that the VCU must be reset or the inverter will not power up on the GS450h, which is the problem I have been having. Thanks.

After a firmware update you need to power cycle the ZombieVerter and check all the settings are correct.
