2.6 Expansion Connectors
2.6.1 Board-to-Board (B2B) Connectors
On the bottom-side, there are two connectors (CN1, CN2). All MCU ports are available here, along
with power-supply and additional control-signals like reset.
Layout and placement of the SK-MB9EF120-002,-003 allow to plug a Fujitsu Multi-I/O board
(
ADA-
FCR4-MULTIIO-001) under the board, providing direct access to the ports via standard-raster
headers along with other features.
Alternatively, a custom PCB can be connected.
2.7 Debugging Facilities
The Starter-kit provides a JTAG-Interface on a 20-pin 2.54mm (0.1in) IDC-header for debugging. The
header uses the standard ARM configuration.
The second facility consists of two ARM-standard trace-connectors (X3, X4). While they can be used
together providing a 32-bit trace-port, the first (X3) can also be used solely with up to 16 trace-lines.
Having the JTAG-signals also available on X3, debugging does not require further connections.
Only one connector-set may be used at the same time: either X2 or X3/X4, because some signals are
shared between them. Debugging requires a conforming interface-adapter and corresponding
software on the host system.
