From af7a34acfd88815ead1882eb8b05ef088d7ca738 Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Thu, 11 Jan 2024 14:35:39 +0900 Subject: fwu: fix fwu_get_image_index interface The capsule update uses the DFU framework for updating storage. fwu_get_image_index() currently returns the image_index calculated by (dfu_alt_num + 1), but this is different from the image_index in UEFI terminology. Since capsule update implementation calls dfu_write_by_alt function, it is better that FWU returns the dfu_alt_num.
