Hi thieuqp 

lpcopen_2_10_lpcxpresso_ea_devkit_4088 has LWIP HTTP Webserver and IPERF Server example.

It doesn't have example for ftp server.

Thanks,

Dear @ZhangJennie . Thank for your reply.

I've porting code from periph_ethernet/enet.c to my project, and all feature is OK: TCP, http server, NTP..., and after reset, Ping time live < 1ms, only connect to ftp server, ping time live increase.

because i'm use thirdparty TCPnet library, then NXP have no examples similar.

pls let me if you have example for ftpserver.

Many thanks.
