Update as I am back on this after a break and still stumped.
uIP:
* only supports GET method
* HTML5 maps PUT to GET which is why I found either caused my CGI app
to run
* But no support for getting the data itself as...it only supports the
GET method
thttpd:
* supports POST, and calls my CGI app where I can save the file that's
sent
* Any calls to puts or printf from within the CGI app fail. There are
pipes in place for stdout but the piped/opened file reports as
unwriteable.
So uIP no use without work; thttpd is broken (issue raised on github)
Anyone know of a lightweight webserver that will handle POST and that
runs under NuttX?

Make that "PUT" not "GET", of course.

And...the magic answer to make this form actually work with the uIP
webserver is that:
1. the form's "method" has to be GET not POST otherwise the URL CGI
"call" is not made visible/sent correctly/processed.
2. the webserver has to be configured with URL/CGI mapping enabled
(CONFIG_NETUTILS_CGIPATH)

Forgive me if the terminology is wrong here, but I am trying to find
documentation - NuttX or elsewhere - about the %! "tag" that denotes
a call to a CGI function. Specifically, I am trying to add a form
that calls a script from a button, where do-firmware-update is my
CGI function:
<form action="%! do-firmware-update" method="post"
enctype="multipart/form-data" accept-charset="UTF-8">
This gets served with nothing after the first opening quote
character on this line so i am assuming I am "calling" the script
incorrectly but can't find anything anywhere to tell me how to do this.
Can anyone point me in the right direction?
Thanks!
