Subject: [U-Boot] [PATCH] am335x: BeagleBones enable CONFIG_AUTOBOOT_KEYED
Date: Thu, 14 Jan 2016 12:15:25 -0600 [thread overview]
Message-ID: <1452795325-29694-1-git-send-email-robertcnelson@gmail.com> (raw)
On startup, the BeagleBone family of boards can occationally halt at
the U-Boot prompt. Due to U-Boot receiving random data on the usart.
Migrate BeagleBone based boards to use CONFIG_AUTOBOOT_KEYED, user
will now have to enter the <SPACE> key to get to U-Boot prompt
