| **Note** The boot button must be kept down for some time after releasing the reset button (or after turning on the power). This time depends on the reset circuitry design. This time usually varies from 0.1 s to 2 s. | **Note** The boot button must be kept down for some time after releasing the reset button (or after turning on the power).

| - | A program is used on the host to control the communication between the target and the host. This program consists of two parts, one running on your Linux host and one that is uploaded to and executed on the target. By setting up this client/server environment the target system can be controlled which, for example, allows for flash programming. This program is distributed with the SDK and is named "etrax100boot" for ETRAX 100LX based designs (which also involves all ETRAX 100LX MCM designs) and "crisv32boot"((It's name "etraxfsboot" in the 2.10 software distribution)) for ETRAX FS based designs. | + | A program is used on the host to control the communication between the target and the host.

| Since the network bootstrap method uses raw Ethernet packages no IP or TCP has to be enabled on either the host or the target. However, this also implies that the packages used will be filtered when trying to pass a router. As a consequence the network boot method will only work if the host and the target are connected to the same network segment. | Since the network bootstrap method uses raw Ethernet packages no IP or TCP has to be enabled on either the host or the target.
