Did I fry my board ?

[mbun]

Hi, I installed Can on the SB2040, everything reports correctly except for my TAP :
The LED on the tap board is red when down and blue when up. So no issues there.
I soldered the opto-TAP board for 5V and had it originally installed on the 3-pin connector with the 5V and gpio28

I later found out that's not the way to do it and moved signal and ground to gpio25, leaving the 5V as is.

Since it's not working anymore I wondered : did I fry my SB2040 ?

Only way to know if you if do some testing. Put it back how it was working and you should know.

Ehm, maybe I wasn't clear but it has never worked. I reinstalled Klipper and Canbus completely after I reconnected it correctly. It didn't work before and it doesn't work now.

So what did not work, CAN bus, TAP, or both?

As stated in my post, everything works except TAP.

I think the easiest way is to just put 5v to the board and try and trigger it. Use the light to identify.

I already said everything works, the Optotap leds reported correctly. That means there was 5V on the board.
However ENDSTOP_QUERY shows the TAP is not working as an endstop. And before you ask, yes it's defined as an endstop in the config.
