Hey,

I’m trying to finish ‘DE0-Nano-SoC_My_First_HPS’ but I created new SD Card, loaded HPS default bitstream from CD but when I plug ethernet cable between my Laptop and DE0-nano-soc i have problem with ethernet. LED’s don’t blinking at PHY connector. I checked cable it’s ok? Anybody have any ideas?

BOARD : Terasic  DE0_Nano_SoC Version-A Board

if you don’t have a router between your laptop and the board you need to set a custom ip, like 192.168.0.1 for the board and 192.168.0.2 for the laptop Ethernet adapter
"udhcpc" is used when you have the board connected to a DHCP server

I had just tried connect the board with my laptop using the cross-over cable using the ifconfig eth0 to set a ip address for my board. Initially the connection is established and i can scp files from my laptop to the board. However, after a few times, it wont work anymore. When I try to scp files to the board, it show the following message:

$ scp -vvv INTERN_DEMO root@192.168.1.1:/home/root
Executing: program /usr/bin/ssh host 192.168.1.1, user root, command scp -v -t /home/root
OpenSSH_6.8p1, OpenSSL 1.0.2a 19 Mar 2015

debug1: connect to address 192.168.1.1 port 22: Connection refused
ssh: connect to host 192.168.1.1 port 22: Connection refused
lost connection

Kindly advise me on how to solve this issue please. Cross over cable is much more portable than router…
