Subject: imx-usb-image write to usb error
Date: Wed, 4 Sep 2013 21:04:36 -0400	[thread overview]
Message-ID: <20130905010436.GP19598@titan.lakedaemon.net> (raw)

All,

This is the first I've messed with i.MX, so I'm a little lost. :)

I'm putting together a patch to add support for the SanDisk Connect
Wireless Media Drive [1], code dump from SanDisk is here [2].  It turns
out when you unplug the battery, it'll show up as the Freescale hid.

Here's what I get:

$ ./scripts/imx/imx-image -c \
arch/arm/boards/sandisk-connect-wmd/flash-header-lpddr1.imxcfg -f \
barebox.bin -o barebox.imx
$ sudo ./scripts/imx/imx-usb-loader -vvvvv ./barebox.imx 
found i.MX50 USB device [15a2:0052]

status failed

Looking at the code, it looks like transfer() is always returning 0
bytes in last_trans.  Has anyone seen this before?  $searchengine came
up blank.  What simple thing am I missing?

thx,

Jason.
