On the OpenWRT router there is same vsftp server but diff version : 3.0.2 and its working perfectly and here is the vsftpd.conf file :

background=YES
listen=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
check_shell=NO
#dirmessage_enable=YES
#ftpd_banner=Welcome to blah FTP service.
session_support=NO
#syslog_enable=YES
#userlist_enable=YES
#userlist_deny=NO
#userlist_file=/etc/vsftpd.users
#xferlog_enable=YES
#xferlog_file=/var/log/vsftpd.log
#xferlog_std_format=YES
