Hi there,
i can osberve same strange thing on Xilinx ZYNQ.
But really strange is:
I'm having a couple of USB-sticks on my desk, about 5pcs.
Exactly one of them is working without any trouble.
My testfile is ~16MB, with the magic usb-stick i can read the whole 16MB
without errors.
With all the other sticks i get this timeouts.
best regards,
Hannes

Hello,
I'm using U-Boot on a custom i.MX6 board and I'm having problems while
reading (large) files from USB thumb drives.
I wouldn't really mind if this only happened with some specific USB
device, but the problem occurs with 3 out of 4 tested thumb drives while
loading a 100M test file.
The devices that work seem to be rather old ones.
The same issue is also reported here:
https://community.freescale.com/thread/377911
I can reproduce this behaviour with u-boot-imx v2014.04 and with
mainline u-boot v2015.10 and v2016.01.
Can someone tell me if this is a known issue?
What could be the reason for this and how can I get this working?
Thanks!

Error reading cluster
** Unable to read file test.file **
What happens if you do 'dcache off' and then read the file ?
Unfortunately turning off dcache doesn't seem to change the behaviour.
I'm still getting the same error messages.
