[En-Nut-Discussion] 4.1.9.6 Available

[Peter Sodermanns]

Hi all,

with 4.1.9 the ftpd seems to work no more.
In my application as well in Ethernuts's ftpd sample I observe the same 
behavior: After opening an ftp connection the system hangs and I have to 
restart.

In ftpd.c I defined FTPD_DEBUG, and in dirent.c I put some printf's into 
function opendir. Also printf's in function NutFtpTransferDirectory, 
leading to the following output:

It seems that NutFtpSendMode fails. At that point the program restarts. 
Before inserting that last printf the program just hang.


Maybe someone has an idea where the faulty behavior comes from?
I'll try to dig further...
