Xiang, Thanks for the tips! I tried to get this working, but I don't see any network interfaces on my nuttx system other than loopback.
I ran the script on my Linux box, it created a nuttx0: interface with an IP address. But on the nuttx simulator all I see is this: nsh> ifconfig > lo Link encap:Local Loopback at UP > inet addr:127.0.0.1 DRaddr:127.0.0.1 Mask:255.0.0.0 Do you have a defconfig that I can run that will bring up NSH? Or any defconfig that will show the network is working? cheers adam On Mon, Feb 10, 2020 at 7:45 PM Xiang Xiao <xiaoxiang781...@gmail.com> wrote: > Adam, please follow this instruction if you want to connect the real > network instead loopback: > > https://github.com/apache/incubator-nuttx/pull/249/commits/1b489449f790c2b4618df9133114bb05f0132e87 > The setup is very simple, you don't need config any IP address manually. > > Thanks > Xiang > > On Tue, Feb 11, 2020 at 2:23 AM Gregory Nutt <spudan...@gmail.com> wrote: > > > > > > > I'm trying to get the NuttX simulator working with TCP/IP networking.
