Hi,
I got a problem with tftp and found this patch.
commit 620776d734e4b126c407f636bda825a594a17723 Author: Pavel Machek pavel@denx.de Date: Tue Aug 18 14:34:26 2015 +0200
tftp: adjust settings to be suitable for 100Mbit ethernet
The default timeout is changed to 100 (ms) and this causes "TFTP error: 'Unsupported option(s) requested' (8)".
Because the option is equal to timeout/1000, now it's zero(100/1000 -> 0) which is not supported. Actually I find in an original doc RFC-2349 which specifies this value should range between "1" and "255" seconds.
So I think there may be a conflict? Look forward to your help.
Check this patch: http://patchwork.ozlabs.org/patch/511761/
I believe it should be applied soon.
This is my test log: => tftp a0000000 gqy/bootscript Using FM1@DTSEC3 device TFTP from server 10.192.208.233; our IP address is 10.193.20.130 Filename 'gqy/bootscript'.
