M-ETK State Machine

Power-On

When the M-ETK is powered up, a compatibility check of the M-ETK adapter is performed. In case of incompatibility, a recommendation will be made to change to an appropriate HSP version.

A handshake with the ECU will be made early in the boot process (Startup Time 1). The complete system boot will occur in parallel (Startup Time 2). For more information, see Hardware specifications.

Stand-By (Sleep)

If for a period of 500ms (or approx. 4.5 seconds after initial power on), there is no link on the network interface and no ECU-ON signal detected the system will change into a low power “standby” mode in the following manner.

• The FPGA changes to a standby mode.

• The Ethernet PHY is set to a standby mode; link detection is still possible.

For more information, see Hardware specifications.

Wake Up

When in Stand-By (Sleep) mode, the M-ETK will wake up when either one or both of the following occurs:

• Voltage is detected on the ECU-ON connection.

• A link/ traffic is detected on the Ethernet connection.

After waking, the M-ETK will boot as per the “Power On” mode.

LED Specification

There are three LEDs displaying the operating mode M-ETK:

LED	State	Definition
Red	On	M-ETK is supplied with power and active.
	Flashing	Incompatible Adapter detected. Please refer to the HSP Tool or M-ETK Web-UI.
Green	Off	The Working Page is valid.
	Flashing	Incompatible Adapter detected. Please refer to the HSP Tool or M-ETK Web-UI.
	On	The Working Page is invalid.
Yellow	Off	ETK: Link Down.
	On	ETK: Link Up.
	Flashing	Incompatible Adapter detected. Please refer to the HSP Tool or M-ETK Web-UI.
