Published : 11 Jan 19
Description
The IEEE Standard 1149.1-1990, IEEE Standard Test Access Port and Boundary-Scan Architecture (JTAG) is a method for verifying designs and testing printed circuit boards after assembly. It is used as the primary means for transferring data to a nonvolatile memory of an embedded system and debugging embedded software.
This application report describes the physical connections for JTAG and design considerations to be taken into account for a custom board. It also shows how to use the JTAG interface on the SimpleLink™ MSP432E4 LaunchPad™ development kit for debugging the onboard microcontroller using an external debugger, or by using the onboard debugger for debugging an off-board microcontroller.
