Debug Interface
The CPU_42A-V1 board supports debugging via 3 different channels:
On-board debugger
Cortex Debug Connector (10-pin)
Cortex Debug+ETM Connector (20-pin)
The Hexagon Application Boards are designed to use "Serial Wire Debug" as debug interface. JTAG debug is
not supported by default because the GPIO P0.7, where the required TDI function is mapped to also, is used by
various Actuator boards connected to the ACT satellite connector.
Note: It is strongly recommended not to use JTAG debug mode, especially if satellites boards are connected,
which uses the GPIO P0.7. For the same reason also do not use the on-board debugger in JTAG debug
mode.
If you want to use the JTAG debug mode through the cortex debug connectors (X400, X401) anyway, enable
the JTAG interface of the XMC device by assembling the pull-up resistor R427 (4k7 Ohm) and the resistor R410
(0 - 33 Ohm).
