picozed does not maintain static ip

Former Member
Former Member over 9 years ago

I connect picozed eth0 port to eth0 on linux host.

I open up Terminal in picozed GUI, and set static IP of picozed by doing:

sudo ifconfig eth0 192.168.3.2 netmask 255.255.255.0 and, using ifconfig, verify that eth0 was indeed set to .192.168.3.2.

I set Linux laptop ethernet port as:

sudo ifconfig eth0 192.168.3.3 netmask 255.255.255.0

From Linux machine:

ping 192.168.3.2

The ping is successful for about a minute or two, then I "Destination Host Unreachable".

I use ifconfig in the picozed terminal, and eth0 is no longer set to 192.168.3.2.

All this is repeatable.  It seems the picozed is not holding its static ip assignment.  If that's the case, how to I get this to work with Matlab, which is expecting picozed to have that static ip?

Thanks -- Jeff

    Hi Jeff.  Try this to stop the service from releasing the IP address according to DHCP timouts:

     

    stop network-manager

     

    Works for me.

    Works for me too.  Thanks Matt.  I suppose I should let Mathworks know about this, their documentation for PicoZed does address this issue at all.

    Thanks Jeff. I'll get in touch with MathWorks. We work closely with them.

    Just to close this one off, the issue here is that to use the MathWorks flow you need to use their Linux image. In that case, there's no need to stop the DHCP network manager.
