From f82921baf869b76521892c65f3c7b09467b2b69d Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Mon, 26 Sep 2011 11:50:28 -0700 Subject: [PATCH] altos: Delay reboot by a second to avoid re-entering idle mode TM and Tm go into idle mode if they receive a packet after boot time. When tebooting the device over the packet link, the packet master would be (rapidly) polling the device for additional data and so the device would invariably receive a packet during bootup and go into idle mode again. Delay the reboot by a second to give the controller time to disable the master end of the packet link.
