From 1ea2301fcfbfc85e38eb51e1144c5ac190c4c320 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20Bie=C3=9Fmann?= Date: Thu, 10 Apr 2014 12:52:50 +0200 Subject: [PATCH] board:tricorder: always work with valid eeprom data MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 890880583d84607e36b52a785a96b167728bbf73 introduced EEPROM parsing and board detection but faild to return a valid tricorder_eeprom struct for backup case. When pressing S200 while reading EEPROM we ignore the value. We returned falsely a tricorder_eeprom struct with uninitialized data which is just garbage. Initialize it by zeroing the whole structure.
