Operating Modes of the EB 200

The EB 200 is operated in stand-alone mode. An external plug-in power supply on connector is used to supply the

module with regulated voltage of 6 to 9 V/1.5 A.

4.1

This mode is used, for example, when the EB 200 evaluation board is operated with a debugger. When the EB 200 is

switched on, the debugger assumes control of the EB 200. The user then assigns parameters to the required registers

and loads the user software with the debug tool.

4.2

If the EB 200 contains a programmed Flash, the boot software that is launched when the EB 200 powers up

recognizes this with an entered Flash image. The boot software then branches immediately to the user software

contained in the Flash. Debugging is then possible using the serial RS232 interface or the debug Ethernet port.

4.3

If the EB 200 is operated in LBU mode, the user must take the following precautions:



Provision of a HW reset from the host



Provision of the 5 V voltage supply and sufficient chassis ground between the EB 200 and host



Configuration of the EB 200 for LBU mode on connector X11 (see Section 2.1.2)



Configuration of the selected boot mode on connector X11 (see Section 2.1.2)

If LBU boot is used as the boot mode, a local Flash does not have to be programmed because the power-up can be

controlled by the host.
