switch.
Connect the Micro USB to USB cable to the Debug port (J-9)and open a terminal
application on the PC using the following parameters:
Rate - 115,200 Bps, data –8 bits, party –none, stop –1bit and flow control –none.
Note that the virtual com number may differ from PC to PC.
Connect an Ethernet network to the Ethernet port for network or WEB access.
Select the right boot source using BT SL 0 and 1 jumpers. The board is supplied with
a demo version installed in the eMMC device.
For activating the desktop application, a VGA cable should be connected to J-18 (The
VGA is set to 768x1024). USB mouse and keyboard can be connected to J13.
Note: The CB-50 is provided with a full Linux version on the eMMC, and preloader and boot
only on the QSPI Flash.
