for the same 1MiB file.  The link line will vary from board to board but
the end result is that I always see 4 T (for timeout) at the end of the
transfer.  On boards where I am doing this on gigabit the initial
transfer is fast enough that the timeout doesn't cause failure.  On the
boards where I'm at 100Mbit instead however, I fail.

I have seen this also - what type of interface are you using?

Does this happen in your testing, Guillaume?


No, I never saw those timeouts. I will try to reproduce here.
On which boards does it happen?

AM335x GP EVM, DRA72x EVM ("J6 Eco"), Beagleboard xM, RPi 3 (32 or 64bit
mode).  I suspect it's something either config or network related.
Everything is on the same 24 port gigabit switch.



I just tried 2016.11-rc2 on a Beagleboard xM with:
* nfs download from a NFSv2 server
* nfs download from a NFSv3 server
* tftpboot download from a TFTP server

And all are working fine here.

I see it on CPSW (am335x, dra7xx) and the USB smsc95xx on rpi3 and the
USB ASIX on omap3_beagle.

[U-Boot] NFS and timeouts?

2016-10-13 Thread Tom Rini 
Hey all,

I've noticed now, but not dug into a problem that goes like this.  On
every platform that I have tried NFS on now (and I wasn't a user before
the test came in) I see:
# nfs 8000 /tftpboot/1MiBtest.bin
link up on port 0, speed 1000, full duplex
#

 ##T T T T
done
Bytes transferred = 1048576 (10 hex)

for the same 1MiB file.  The link line will vary from board to board but
the end result is that I always see 4 T (for timeout) at the end of the
transfer.  On boards where I am doing this on gigabit the initial
transfer is fast enough that the timeout doesn't cause failure.  On the
boards where I'm at 100Mbit instead however, I fail.
