3.5.2 SAMG55J SWD/JTAG Port
The PL360G55CF-EK board includes an SWD (Serial Wire Debug) / JTAG interface port to provide debug level access to the system-on-chip. It also embeds a serial wire trace. This connector provides the required interface for in-circuit emulators, like the Atmel-ICE or SAM-ICE. The SW-DP/JTAG port is a 10-pin, dual row, 0.1-inch male connector (J7). When using the SAM-ICE, a JTAG adapter for 20 to 10 pins is necessary, e.g., this one.
Important: Note that the
PL360G55CF-EK kit does not include either SAM-ICE or Atmel-ICE JTAG emulators.
Please refer to the SAMG55 datasheet for further description of the JTAG debug port.
CAUTION: The USB JTAG/SWD connector
is not isolated from mains. Please make use of proper isolation (i.e.: USB isolator device)
if using this connector when the board is not galvanically isolated (using a PLC Coupling
design which it is not isolated from mains). Take into account the possible noise
interference that these isolators could be adding to the PLC network. For instance, you can
use the UH401.
