Subject: mw crash
Date: Thu, 23 Feb 2017 15:24:33 -0800	[thread overview]
Message-ID: <CAFXsbZo1X6FQ5F8560oAzuf9eygzS22WPxjFwGpo26887NswCQ@mail.gmail.com> (raw)

I mistakenly used the wrong set of command line arguments when using
the mw command and it resulted in the following crash:

barebox@ZII RDU2 Board:/ mw -b -l /dev/pic_eeprom_rdu 0x50 3

I haven't dug in to figure it out but I figured it would be good to report.
