From 41a077d2b1c94d208c34509e6361d159cab83367 Mon Sep 17 00:00:00 2001 From: Zakharov Vlad Date: Fri, 27 May 2016 20:51:41 +0300 Subject: [PATCH] uboot: Use "mdbtrick" target when building elf for ARC By default position independent executables (PIE) are generated when building U-Boot elf target. MetaWare debugger doesn't support PIE (position-independent executable). In order to allow MDB load and run U-Boot elf, we need to do a special trick, called "mdbtrick". This special build target is used to fake generated U-Boot elf by: 1. Reset PIE flag in ELF header 2. Strip all debug information from elf Signed-off-by: Zakharov Vlad Signed-off-by: Thomas Petazzoni --- boot/uboot/uboot.mk | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/boot/uboot/uboot.mk b/boot/uboot/uboot.mk index bc5d952bbe..a2274eea71 100644 --- a/boot/uboot/uboot.mk +++ b/boot/uboot/uboot.mk @@ -38,6 +38,10 @@ endif ifeq ($(BR2_TARGET_UBOOT_FORMAT_ELF),y) UBOOT_BIN = u-boot +# To make elf usable for debuging on ARC use special target +ifeq ($(BR2_arc),y) +UBOOT_MAKE_TARGET = mdbtrick +endif else ifeq ($(BR2_TARGET_UBOOT_FORMAT_KWB),y) UBOOT_BIN = u-boot.kwb UBOOT_MAKE_TARGET = $(UBOOT_BIN) -- 2.30.2
