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 80000000 /tftpboot/1MiBtest.bin link up on port 0, speed 1000, full duplex ################################################################# ################################################################# ################################################################# ##########T T T T done Bytes transferred = 1048576 (100000 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.
I have seen this also - what type of interface are you using?
I see it on CPSW (am335x, dra7xx) and the USB smsc95xx on rpi3 and the USB ASIX on omap3_beagle.
