If you encountered this phrase on a forum like Badcaps, XDA Developers, or GitHub, you are likely looking at instructions for unbricking a device. Many Android tablets, automotive head units, or IoT devices use generic Chinese reference designs. The Unified Definition: The E7A MB PCB V3
For example, a factory might produce an "E7A" platform motherboard. To restore firmware on a V3 of this board, you might need to short two specific points (E7A pins) to force the processor into "Download mode" before you can establish a link with a PC via USB.
In this scenario, the phrase is an instruction: "On the E7A motherboard, PCB revision V3, you must create a link (short) between these two test points to enter flashing mode."
