Trouble getting ftpd to run about lwip-ftpd

[toelke]

I have never used the passive mode...
As far as I can see you have a complete and correct FTP-Transaction listing all files in /. It gets closed in packets 90-93.
Strangely, the ftp-server only sends the "226 Closing data connection" only after the client closes the control connection in packet 420.

Is the rest of you lwip working? Which port are you using? Are the *_tmr called regularily?

You name it! 5min ago, I also found out
  that the ftpd_msgpoll routine is not called. It is because I use
  an operating system (SYS/BIOS), I think. From where do I have to
  call the _tmr functions?

  Thanks, and regards,
  Daniel

Please read [1] and [2]. Calling "sys_check_timeouts" should suffice.
The mailing list https://lists.nongnu.org/mailman/listinfo/lwip-users will gladly help you with this and other problems in getting the stack to work.

I found the problem
It was the define for MEMP_NUM_SYS_TIMEOUT, it was one too little. Therefore there was a failure in memp_malloc(MEMP_SYS_TIMEOUT), so the timers did not run. In turn, also the poll function of ftpd was not called.
Thanks for your help!
