JTAG - Joint Test Action Group
JTAG is a standardized interface for debugging integrated circuits which you can use to debug your BeagleY-AI.
(*) - JTAG is not available on the 40 Pin Header on BeagleY-AI. The interface is instead available via the TagConnect 10 pin connector under the USB Type-A ports.
Due to space constraints, the original retaining clips will not fit, but a 3D printable version is available on Printables.
