Configure Ethernet adapter with static IP to work with Xilinx SDSoc Zynq board (Zybo)
SDSOC debug of Zynq board with USB Ethernet adapter
You could plug the board into a network or router and allow the board to obtain an IP via DHCP.
Alternatively, you can use a USB adapter to connect your host PC directly to the board, and this post describes how you do this.
Procedure
- Connect the USB adapter and install the driver.
In windows, configure the network interface to have a static IP (192.168.0.1)
- Identify the network connection, then go to:
Windows Network connections> [connection name] and double click to open the status
- Click on Properties > Internet Protocol Version 4 (TCP/IPv4) > properties
- Select Use the following IP address
IP address: 162.168.0.1
subnet mask: 255.255.255.0
- Boot the Zynq board, and from a command prompt, check the ip
> ifconfig
You should see something similar to this:
eth0 Link
encap:Ethernet HWaddr 00:0A:35:00:01:22
UP BROADCAST
RUNNING MULTICAST MTU:1500 Metric:1
RX

collisions:0 txqueuelen:1000
RX
bytes:23411 (22.8 KiB) TX bytes:2394
(2.3 KiB)
Interrupt:143 Base address:0xb000
There is no IP address configured for eth0. (It expects to receive an IP via DHCP)
Set IP address dynamically
To dynamically change the IP (need to do this every time the board is power cycled)
>ifconfig eth0 192.168.0.10
Set IP address statically
To change the settings for the adapter in the network interfaces settings (saving this to the filesystem will retain the settings after power cycling):

>ifconfig eth0 192.168.0.10
Set IP address statically
To change the settings for the adapter in the network interfaces settings (saving this to the filesystem will retain the settings after power cycling):
- Start vi and edit /etc/network/interfaces
>vi /etc/network/interfaces
** Tips for vi; **
se the arrows to navigate to the point in
the file you want to edit.
Press i (insert) to move to edit mode, and use delete to
remove
Press ESC :wq<enter> to save and quit
- Modify the file to include:
auto lo
iface lo inet loopback
#
auto eth0
iface eth0 inet static
address
192.168.0.10
network
192.168.0.1
netmask
255.255.255.0
- Reset the interface
>ip addr flush dev eth0 && ifdown -a && ifup
-a
- Check the IP address:
>ifconfig
eth0 Link
encap:Ethernet HWaddr 00:0A:35:00:01:22
inet addr:192.168.0.10 Bcast:192.168.0.255 Mask:255.255.255.0

Interrupt:143 Base address:0xb000
Check connection to host:
>ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
64 bytes from 192.168.0.1: seq=0 ttl=128 time=2.081 ms
J
In SDSoc, create a New Target Connection
Give it a name, and use the IP of the board as the host (192.168.0.10) and click OK.
You should now be able to debug

Make a data entry form in access 2010
To use an Access 2010 form to enter data into a table, (assuming the table already exists)
- Once the form is created, open the form in Design View.
- In the properties section, in the Data tab, there is a Data Entry Option, Data Entry

Zedboard Test Application for GPIO (Including MIO/EMIO)
