From 6bf4ca076f8c7a3c1c5abd1cbb059516f7af15df Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Mon, 3 Mar 2014 12:19:29 +0100 Subject: tools, fit: add fit_info host command add fit_info command to the host tools. This command prints the name, offset and the len from a property from a node in a fit file. This info can be used to extract a properties data with linux tools, for example "dd".
