mvme177: pty's

[Joel Sherrill]

I don't think you configured any extra file descriptors. I am on my phone but it should be CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS or something very similar to that.

Hello,

I've been working the bsp for the mvme177. It's looking pretty good at
this point.

Currently, I'm trying to get rshell to work. After some debugging I find
that the "spawned_shell()" function
in "telnetd.c" is trying to open "/dev/pty0" and failing. I tried to do
a simple "fopen("/dev/pty0", "r+")" within
"main.c" and that fails as well.

Here are my configs from "main.c": The "CONFIGURE_SHELL..." stuff is
commented out here, but enabled in another file.
