From 56b906f535ac2f86bcab71addbbcd376d74f6a73 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Mon, 23 Aug 2010 22:03:36 -0700 Subject: altos: Place rom config variables in fixed location The device serial number and radio calibration values are stored in flash, mostly so that TeleDongle gets them saved. Placing them in well-known locations (starting at 0xa0) makes it possible to find the previous configuration and to re-write it easily, without requiring the .map file. altosui doesn't have the .map file parsing code, so it relies upon this new technique. As a benefit, it reads the old values from the device before reprogramming it.
