How does boundary scan work
WebMay 1, 2024 · The JTAG boundary scan is a bit of magic that gives you total access to the device pins without difficult soldering. It also means you can do tasks such as dumping the contents of a memory chip by simply driving the required SPI signals out the I/O pins of the microcontroller (MCU). Boundary scan is a method for testing interconnects (wire lines) on printed circuit boards or sub-blocks inside an integrated circuit. Boundary scan is also widely used as a debugging method to watch integrated circuit pin states, measure voltage, or analyze sub-blocks inside an integrated circuit. The Joint Test Action Group (JTAG) developed a specification for boundary sca…
