M-ETK State

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 (Start-up Time 1). The complete system boot will occur in parallel (Start-up Time 2). For more information, see Hardware specifications.

Standby (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 Standby (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.
