I'm using the Makefile on Linux, so if your build environment is different you may have to link in dswifi9d yourself. It is a little ugly and I just noticed there's potential for a pretty enormous memory leak in the main loop, but I don't think it should be troubling us here.
tftp.c contains pretty much all the networking stuff, and if I haven't changed it too much, tftp.c.orig can be swapped in to try the select()-based version.
The .nds is of the version with my own timeout loops written. Which, by the way, has proved to be no more reliable than the select() version after all, and slightly slower to boot. (The latter is to be expected.)
main.c allocates and fills a buffer of 1 MiB and will send it to any connecting TFTP client. In my tests I used the client in the tftp-hpa package on Ubuntu/Debian (primarily because it let me use a port number other than 69 and I developed the server on Linux first). Tested it with this command:
Code: Select all
while time tftp 172.22.216.131 -c get test;do date;done
EDIT: I just got a Guru Meditation Error running it again, at least a handful of packets away from the end of file.
Code: Select all
Guru Meditation Error!
data abort!
