From 2092e4610485618ec7a676ff8e6d297ea9dca3d5 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 24 Aug 2015 00:21:46 +0200 Subject: dfu: tftp: update: Add dfu_write_from_mem_addr() function This function allows writing via DFU data stored from fixed buffer address (like e.g. loadaddr env variable). Such predefined buffers are used in the update_tftp() code. In fact this function is a wrapper on the dfu_write() and dfu_flush().
