How to convert EWC?? (transfer command failed (Error 143))

JustTakeTheFirstStep — Thu, 21 Jul 2022 05:45:13 GMT

I want to convert 9115 LAP to EWC.

But I am getting error 143 while uploading the TFTP image.

Cables are no problem.

I tried versions 17.08.01 , 17.03.04c , 16.12.07 .

What the hell is the problem?

There seems to be enough flash space.

- Check the tftp server's logs after the failed transfer , or if available on the command line -> use another transfer protocol such as ftp or scp.

Or try to use another TFTP server, some of them used to close the connection after some short time.

- Indeed , sometimes you then need to increase tftp timeout on the tftp server (if available)

I used 3cdaemon as my TFTP server.

I have successfully uploaded the image using tftpd64.

These issues occur with the 9115.

On the 9130 it was not a problem.
