From 08e061327571c8431afe1edd5ad418ef4c677315 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 5 Nov 2013 16:31:14 +0000 Subject: [PATCH] ar71xx: generate recovery image for WNDR4300 Extended the Makefile to generate a working factory reset image for Netgear WNDR4300. The image uses UBI with two volumes squashfs (rootfs) and JFFS2 (rootfs_data). In order to make stock U-Boot happy, a fake rootfs image is placed into the last erase block of the kernel partition. Signed-off-by: Stefan Agner [juhosg: - restore the NetgearNAND/initramfs macro, - remove unused {Squash,Ubi}fsTemplate macros, - remove board specific mtd options from CONFIG_CMDLINE, append the board specific ubi.mtd parameter to the kernel command line instead, - increase kernel partition size to 2MiB, - use board specific ini file for ubinize, - put jffs2 eof mark into the rootfs_data ubi volume, - use KDIR_TMP for temporary images, - use the squashfs-raw image, - increase kernel partition size to 2MiB, - use a local ubinize macro, - fix macro parameter comments, - put the fake rootfs into the last erase block of the kernel partition, - move Image/Build/NetgearNAND/buildkernel macro before define Image/Build/NetgearNAND, - don't use the wndr3700 utility, use '-M' parameter of mkimage to set the uImage magic, - use '-recovery' suffix for the generated image, it is only usable via the fw_recovery function of the bootloader, - update commit log] Signed-off-by: Gabor Juhos SVN-Revision: 38655 --- target/linux/ar71xx/image/Makefile | 72 ++++++++++++++++++- .../linux/ar71xx/image/ubinize-wndr4300.ini | 27 +++++++ 2 files changed, 97 insertions(+), 2 deletions(-) create mode 100644 target/linux/ar71xx/image/ubinize-wndr4300.ini diff --git a/target/linux/ar71xx/image/Makefile b/target/linux/ar71xx/image/Makefile index b1909ddcc74e..811da74bcf61 100644 --- a/target/linux/ar71xx/image/Makefile +++ b/target/linux/ar71xx/image/Makefile @@ -144,6 +144,17 @@ Sysupgrade/KR=$(call CatFiles,$(2),$(3),$(KDIR)/root.$(1),$(4),$(call sysupname, Sysupgrade/KRuImage=$(call CatFiles,$(KDIR_TMP)/vmlinux-$(2).uImage,$(3),$(KDIR)/root.$(1),$(4),$(call sysupname,$(1),$(2)),$(5)) Sysupgrade/RKuImage=$(call CatFiles,$(KDIR)/root.$(1),$(4),$(KDIR_TMP)/vmlinux-$(2).uImage,$(3),$(call sysupname,$(1),$(2))) +# $(1): ubinize ini file +# $(2): working directory +# $(3): output file +# $(4): physical erase block size +# $(5): minimum I/O unit size +# $(6): custom options +define ubinize + $(CP) $(1) $(2) + ( cd $(2);
