I am using Putty to establish a telnet connection with the network interface module. I am also using tftpd64 for loading the configuration file (.load) in the NVM of the module through bootloader. As per the procedure described I should use the load command in Putty. However when I using the load command, I am getting a reply that "Unknown command". I don't understand the reason for this.
The TFTP server that this platform has been tested with is available for download in the Developer Portal. I have not used the utility you are specifying so I cannot speak to it immediately. Could you provide a screenshot of your telnet command so I can get a better idea of what you are seeing.
Thank you very much.
