From 8d6b73202c65f40f88ac27f5e5d2203fe6ae3f1d Mon Sep 17 00:00:00 2001 From: Andreas Pretzsch Date: Sat, 16 Jul 2011 05:50:59 +0000 Subject: automatic update from FIT image: add optional address parameter Current update_tftp() flow: 1.) fetch "updatefile" from defined TFTP server 2.) check if FIT format 3.) flash contained images Add an address parameter to update_tftp(). If this address is non-zero, skip the TFTP transfer and use the image at this address. Also extend update_tftp() to return success/fail.
