When the expected operation is not performed during the operation of TW100MJ (the same for TW100XR\/TW100PC), checking the debug messages is the best way to determine where the problem occurred.<\/p>\n\n\n\n

TW100MJ provides the capability to output messages via the serial debug port for each operation.<\/p>\n\n\n\n

Debug Port<\/h2>\n\n\n\n

The debug port of TW100MJ is a UART port.<\/p>\n\n\n\n

The default setting of the UART port is as follows and cannot be changed.<\/p>\n\n\n\n

Connecting to Debug Port<\/h2>\n\n\n\n

Using the on-board port<\/h3>\n\n\n\n

The TW100xx Series modules provide a 4-Pin Hole debug port to allow checking of debug messages in case the system does not provide a connection to the TW100xx module’s debug port after the module has been installed in a separate system.<\/p>\n\n\n

Pinout of the TW100xx Debug port<\/figcaption><\/figure>\n<\/div>\n\n\n

By connecting the 4 Pin Hole to a TTL-to-USB module as shown in the image below, you can view debug messages.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Note that the TTL-to-USB module must support a baud rate of 2Mbps in order to monitor the debug messages.<\/strong><\/p>\n\n\n\n

In case of using Header pin<\/h2>\n\n\n\n

The Header pins (MiniPCI Connector pins in case of TW100PC) provided can also be used for the Debug Port in order to connect to external systems.<\/p>\n\n\n\n

For TW100MJ\/TW100XR, the pins for the Debug Port are J6 Pin3 (Console_TX) and J6 Pin4 (Console_RX), and for TW100PC, the pins are Pin25 (Console_TX) and Pin26 (Console_RX).<\/p>\n\n\n\n

In EVB(Evalution Board)<\/h3>\n\n\n\n

The TW100xx EVB has the Debug port connected to the USB Connector (J7) which is also used for power supply.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

By connecting the USB cable connected to the PC to J7, the serial port will be recognized on the PC, and you can check the Debug messages through this serial port.<\/p>\n\n\n\n

Procedure for checking debug messages<\/h2>\n\n\n\n

Using a terminal program<\/h3>\n\n\n\n

Run any serial terminal program. In this case, PuTTY is used.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Power-on or Reset Pin Triggering<\/h3>\n\n\n\n

Apply power to the module or trigger a reset. Then, you can see the debug messages being outputted.<\/p>\n\n\n
