Arduino Nano ESP32 netlist generation problem

[fpetzold]

I am relying to connect a TFT display to an Arduino Nano ESP32 board on the Jumperless. Ir works fine when I (wrongly) select an ordinary Arduino Nano as the controller in Wokwi but one connection does not get generated in the setlist if I use the board-arduino-nano-esp32.

Note the difference in index 2, the 5V is also connected to "8" in the Arduino case.

I had a look at the python code but could not figure out where the additional connection for 5V is coming from. I suppose this connection is the one that makes the difference.

It looks like you misplaced one of the jumpers in Wokwi:

Let me know if that fixes it.

[fpetzold]

I feel extremely stupid now... Yes, that fixed it.

Don't feel bad, I've spent hours trying to fix what I thought was a routing bug that ended up being exactly this.
