Board Connections
Connect the following to your PC:
•
Connect CN3 on the board to a USB Host connector on your PC. This provides USB DFU.
•
Connect CN6 on the board to a USB Host connector on your PC. This provides
Serial-over-USB and JTAG-over-USB services. After the FTDI driver has been installed on
your PC, four additional virtual serial ports will exist. The board uses the 3
rd
port for UART
output at 115200,8,n,1. On Linux PCs, if you have no other serial-over-USB devices
attached, this is accessed using /dev/ttyUSB2.
•
If the board is powered by USB, press switch SW9 to perform a soft reset.
•
If you wish to use Ethernet, but do not have an Extension Board, you can connect CN1 on
the board to a dedicated Network Interface Card (NIC) on your PC. This is used by U-Boot
to access GMAC2 via the 5-Port Switch on the RZ/N1 device. Note that the U-Boot driver
for the 5-Port Switch simply configures it as an unmanaged switch.
•
If you wish to use Ethernet, and are using the Extension Board, you can connect J22 of the
Extension Board to a dedicated Network Interface Card (NIC) on your PC. This is used to
access GMAC1 on the RZ/N1 device.
•
By default, the board uses static IP addresses, so please ensure your host’s NIC is set up
with a static IP address of 192.168.1.30. This address is set by default in the U-Boot
serverip environment variable.
