Hi
  I have done the ecos-3.0 porting that include bsd-tcpip stack and ftp
server (http://www.meduna.org/sw_ecosftpserver_en.html).
  But I got the problem on ftp client connection, when I try to set
optimization flag to -O2 with kernel build the bug was fixed!
  When I trace the code i found FILE IO API “getsockname” always sent wrong
IP address (0.0.0.0) and this was reason make connection
  fail.
  Is anyone get the same question?


cdl_option CYGPKG_KERNEL_CFLAGS_ADD { # Flavor: data # No user value, uncomment the following line to provide one. # user_value -O2 # value_source default # Default value: -O2

What's your target? What toolchain did you use?
