Subject: [PATCH 1/7] af9015 Slow down download firmware
Date: Sat, 12 Nov 2011 15:54:47 +0000 [thread overview]
Message-ID: <4ebe96cb.85c7e30a.27d9.ffff9098@mx.google.com> (raw)
It is noticed that sometimes the device fails to download parts of the firmware.
Since there is no ack from firmware write a 250u second delay has been added.
