v0.4.3d board, clone Elegoo Mega2560 with 16u2. The injector and ignition outputs quit and stay that way as soon as the USB cable is plugged into the laptop only when Tunerstudio (or any other serial monitor on that port) is NOT running. As soon as TS is launched the board comes back to life.
This only happens with firmware 202201 and newer, the older firmware works fine. I have the reset jumper in place, have tried different computers, scoped the reset pin and it stays at 5v, tried a usb cable with no 5v, tried the custom firmware for the 16u2 and all available reset lock settings. Nothing seems to change this behavior except using old firmware?
The tune is the default from speedyloader.
Any ideas? Anyone else seen this? I have a video of it on the Arduino FB page. Thanks
Mike
