From 21d3a8f8230ae4f1f9210d6ec40f92ae023ec43a Mon Sep 17 00:00:00 2001 From: Matt Mower Date: Tue, 8 Jul 2014 22:25:38 -0500 Subject: Allow custom bootloader msg offset in block misc Use board define BOARD_RECOVERY_BLDRMSG_OFFSET with a decimal integer to define a custom offset where the bootloader message should be read/written. Edify commands get_stage and set_stage need to be aware of the custom bootloader msg offset because they write the stage directly to the BCB.
