Hi ! You can find it the doc here : https://github.com/zegreatclan/AssettoCorsaTools/wiki/Nextion-Display#wiring-nextion-displayGood Morning, I think i found the Issue on my Display, i have this Controller in Connection

Can you give me Help to set the wire to the Display ?
+5V
TX
RX
GND
But I don't see any relation between sd-card upload and a potential wrong wiring. Moreover it was working on the previous template so it means it was correct.
