Tool/software: Linux
Presently I have a beaglebone and a windows laptop connected together via a switch.
Edited the /etc/network/interfaces to assign static ip address to eth0 as 192.168.1.21. Snapshot of the file is given below :
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
#
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
iface tiwlan0 inet dhcp
wireless_mode managed
wireless_essid any
iface atml0 inet dhcp
# Wired or wireless interfaces
#auto eth0
#iface eth0 inet dhcp
# pre-up /bin/grep -v -e "ip=[0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+"
#/proc/cmdline > /dev/null
# udhcpc_opts -R -b
#BE ifcace eth0 (wired)
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.21
netmask 255.255.255.0
#auto eth0
#iface eth0 inet static
# address 192.168.0.20
# netmask 255.255.255.0
# network 192.168.0.0
# broadcast 192.168.0.255
# gateway 192.168.0.1
#pre-up /bin/grep -v -e "ip=[0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+"
iface eth1 inet dhcp
# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
auto usb0
iface usb0 inet static
address 192.168.7.2
netmask 255.255.255.252
# Bluetooth networking
iface bnep0 inet dhcp

Then modified the /etc/udhcpd.conf to run the dhcp server from static address 192.168.1.21 (snapshot below):
# Sample udhcpd configuration file (/etc/udhcpd.conf)
# Values shown are defaults
# The start and end of the IP lease block
#start 192.168.0.20
#end 192.168.0.254
start 192.168.1.30
end 192.168.1.254
# The interface that udhcpd will use
interface eth0
#interface wlan0
# The maximum number of leases (includes addresses reserved
# by OFFER's, DECLINE's, and ARP conflicts). Will be corrected
# if it's bigger than IP lease block, but it ok to make it
# smaller than lease block.

eth0 takes the static ip address, if after reboot I run /etc/init.d/networking reset.
ps -e shows the udhcpd is running:
root@am335x-evm:/etc/network# ps -e | grep udhc
869 ? 00:00:00 udhcpd

I restart the windows laptop and check the ip address. I was hoping to see the assignment in 192.168.1.30 ----- 254 range. However I see autoconfigured or 192.168.56.1
A solution or insight would be appreciated.
Best regards
