Hi ,

We are using AM1705 with SPI flash as SPI boot and XDS100V2 for programming.

We are not able to proceed further due to following issues:-

Hi, Riki,

AM1705 is not a supported device, but from the logs, you may want to check your tftp server set up is correct.

Hi Rex,

Thank you for your reply, As per your suggestion I have check my TFTP server settings, below is my TFTP server setting file.

1) My TFTP service file is :
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot
disable = no
}

2) When I tried to verify TFTP is running, I tried as shown below. It seems TFTP server is working.
I placed a small "test.txt" file with some content in /tftpboot path of the TFTP server obtain the IP adderss of the TFTP server using ifconfig command.

Then some other system I fallow the following steps.

tftp 192.168.1.51
tftp > get test.txt
sent 24 bytes in 0.0 seconds.
tftp > quit
cat test.txt (Here I get same data whatever I have put "text.txt" in /tftpboot directory on TFTP server system )

Can you please check my TFTP services, if any modification required in that file please tell me.

Best Regards,
Riki

Riki,

For generic Linux questions, please check with Linux open forum. For tftp server setup, please see askubuntu.com/.../how-do-i-install-and-run-a-tftp-server.
