[ECOS] TFTP Problem

[ECOS] TFTP Problem

[Marek Łącki]

Hi
I have problem with TFTP client . I created server and client tftp on  two
MPC 860. When I connected to server with another client ( from Cygwin) all
wroked correctly but if I used eCos tftp client and try to get a file , I
coudn't do it. When anlalised a net packets , I saw that client sent a
request and server responsed. Server sent a packet ( file) to client but
client coudn't receive it. Function tftp_get returned -1 ; What is wrong ???

Look at the *err argument you passed to tftp_get() and decode it from
tftp_support.h in your include hierarchy in your install tree.

Looks like it timed out ;-).

The TFTP client waits 5 seconds before timing out an initial connection. If
you edit net/tcpip/current/include/tftp_support.h, and incrase
TFTP_TIMEOUT_PERIOD it might help, if your server isn't replying fast
enough.

If that doesn't help, you should probably try debugging tftp_get().

 I passed to tftp_get() = 8 (Time out) ; What is wrong ???
