2.2.4 JTAG Headers

The BP-CC3351 was designed with 2 JTAG headers (J10, J11) for SWD interface with the XDS110 debug probe. The signal assignment for these headers are described in the figures and tables below.

The main JTAG interface for the BP-CC3351 is via the LP-XDS110 (ET) that is connected to the 20pin header (J11). A XDS110 debug probe can also interface with this board via a 10-pin header (J10), however this header is not populated with the default kit.
