Linux/AM5728: tftp server on EVM

Ilya Kravchuk

Part Number: AM5728

Tool/software: Linux

I'm trying to configure tftp server on sitara am5728 evm board.
I've edit following string in the /etc/inetd.conf : tftp dgram udp wait nobody /usr/sbin/tftpd /tftpboot
Than I've created /tftpboot dir with file hello.txt and changed it's owner and access flags as follows:
$ mkdir /tftpboot
$ chmod -R 777 tftpboot
$ chown -R nobody tftpboot

When I calls inetd and try to get something from this server via tftp Ubuntu client, only "Transfer timed out." appears and pulled file is empty.
Ping between EVM and Ubuntu is normal.

What am I doing wrong? tftp get process and ping log are attached below.

Hi Ilya,

Are both of your devices configured with static IPs? Or are you using DHCP server on the host machine?
Whicheve it is make sure both devices are configured the same way.

Best Regards,
Yordan

Board is in the same network as my PC and they both get IP's via DHCP server. Ubuntu is installed as virtual machine on this PC and is connected to the network via bridge configuration

I've rewrote /etc/inetd.conf as it describes in the busybox documentation: 69 dgram udp nowait root tftpd tftpd /tftpboot

And timeout error was changed on the "malformed packet"

I also tried to send files from EVM to PC like as tftp -pl hello 192.168.0.116 and get the following error: "tftp: server error: (2) Access violation"
But getting file from PC to EVM successfully completes after this command: tftp -gr Ubuntu_hi 192.168.0.116
