From 7e9b93fb1b9d1f04df905b77d79ef8a182b2fb83 Mon Sep 17 00:00:00 2001 From: INAGAKI Hiroshi Date: Tue, 1 Jan 2019 09:15:34 +0900 Subject: [PATCH] base-files: allow non-standard rootfs volume name in UBI in sysupgrade This commit allows to use non-standard UBI volume name as the rootfs volume in sysupgrade. ex.: The U-Boot on Buffalo WXR-2533DHP checks existence and checksum of "ubi_rootfs" volume when booting, so this name is required. OpenWrt currently provides several patches: 490-ubi-auto-attach-mtd-device-named-ubi-or-data-on-boot.patch 491-ubi-auto-create-ubiblock-device-for-rootfs.patch 492-try-auto-mounting-ubi0-rootfs-in-init-do_mounts.c.patch to facilitate ubi rootfs automount. However the upstream kernel also supports the means of booting from a fully custom ubi partition name and ubi volume name via bootargs/kernel's cmdline parameters: ubi.mtd=mtd_partition_name ubi.block=rootfs_volume_name root=/dev/ubiblock$X_$Y For more information and examples visit the wiki over at linux-mtd: Signed-off-by: INAGAKI Hiroshi Signed-off-by: Christian Lamparter [reworded commit] --- package/base-files/files/lib/upgrade/nand.sh | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) diff --git a/package/base-files/files/lib/upgrade/nand.sh b/package/base-files/files/lib/upgrade/nand.sh index 42f488c118..99916a4e96 100644 --- a/package/base-files/files/lib/upgrade/nand.sh +++ b/package/base-files/files/lib/upgrade/nand.sh @@ -10,6 +10,9 @@ CI_KERNPART="${CI_KERNPART:-kernel}" # 'ubi' partition on NAND contains UBI CI_UBIPART="${CI_UBIPART:-ubi}" +# 'rootfs' partition on NAND contains the rootfs +CI_ROOTPART="${CI_ROOTPART:-rootfs}" + ubi_mknod() { local dir="$1" local dev="/dev/$(basename $dir)" @@ -99,7 +102,7 @@ nand_restore_config() { local ubidev=$( nand_find_ubi $CI_UBIPART ) local ubivol="$( nand_find_volume $ubidev rootfs_data )" [ !
