When I execute "make monitor" I get this:$ make flash monitor

Which is coming from the local program, not the target. No combination of button pushing/holding provokes the target into any output.--- idf_monitor on COM7 115200 ---

Our board is intended to be as identical to the WROOM as possible.

If nothing, then we have an even bigger mystery. I suspect that you will see data ... we then need to follow that data to see where it goes and where it is being lost. What is the schematic of the RX/TX from the ESP32?
Yes.Are you using a UART->USB module/component?
Not at all...in fact, I'd bet they're not. I'll take your suggestion to the HW guy and have him take a closer look. Thanks...How confident are you that the TX signals coming out of the physical ESP32 are making their way to your PC?
