Preparing the xPRESS motherboard
We recommend that you erase the memory on the xPRESS motherboard before running
a new application. This is especially important when running SAM-BA because the default
application on the xPRESS motherboard is designed to reconfigure the USB “OTG” port
to simulate a keyboard and the SAM-BA will not communicate with this interface when it
is in this mode. The steps to follow erase memory are as follows.
1. Power down the xPRESS motherboard. The red “Power” LED must be off. Depending
on the position of the “Always-on” jumper, you may have to disconnect all sources of
power, including the AC Adapter, USB cables, and rechargeable Li-ion battery.
2. If you have installed a coin cell battery in the round socket (shown below), you should
remove it.
3. Move the memory jumper to the erase position.
4. Apply power to the xPRESS motherboard (ideally using AC Adapter). Use the “ON/
OFF” switch to turn the board on (or move the power jumper into the always-on
position) for 10 seconds.
