From dc50694bd1a8f81b40c185bc8cacbdc8e821a3c6 Mon Sep 17 00:00:00 2001 From: Stefan Lippers-Hollmann Date: Fri, 18 May 2018 03:00:41 +0200 Subject: ipq806x: increase kernel partition size for the Netgear r7800 Starting with kernel 4.14 and gcc 7, the kernel doesn't fit into the 2 MB reserved for the kernel partition by the OEM firmware anymore. This patch increases the kernel partition from 2 MB to 4 MB, at the expense of the rootfs, for all supported kernels. WARNING: This breaks sysupgrade! Flashing a firmware containing this changed partitioning from an older image with 2 MB reserved for the kernel partion requires the tftp recovery procedure, thereby losing all settings. This patch is based on a corresponding change by Pavel Kubelun and has been tested by Michael Yartys Signed-off-by: Stefan Lippers-Hollmann --- .../ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8065-r7800.dts | 6 +++--- .../ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8065-r7800.dts | 6 +++--- target/linux/ipq806x/image/Makefile | 2 +- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8065-r7800.dts b/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8065-r7800.dts index 63cb42a3e2..a590fadd0e 100644 --- a/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8065-r7800.dts +++ b/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8065-r7800.dts @@ -359,12 +359,12 @@ kernel@1480000 { label = "kernel"; - reg = <0x1480000 0x0200000>; + reg = <0x1480000 0x0400000>; }; - ubi@1680000 { + ubi@1880000 { label = "ubi"; - reg = <0x1680000 0x1E00000>; + reg = <0x1880000 0x1C00000>; }; netgear@3480000 { diff --git a/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8065-r7800.dts b/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8065-r7800.dts index 63cb42a3e2..a590fadd0e 100644 --- a/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8065-r7800.dts +++ b/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8065-r7800.dts @@ -359,12 +359,12 @@ kernel@1480000 { label = "kernel"; - reg = <0x1480000 0x0200000>; + reg = <0x1480000 0x0400000>; }; - ubi@1680000 { + ubi@1880000 { label = "ubi"; - reg = <0x1680000 0x1E00000>; + reg = <0x1880000 0x1C00000>; }; netgear@3480000 { diff --git a/target/linux/ipq806x/image/Makefile b/target/linux/ipq806x/image/Makefile index a737e165b0..e5df7275a1 100644 --- a/target/linux/ipq806x/image/Makefile +++ b/target/linux/ipq806x/image/Makefile @@ -149,7 +149,7 @@ TARGET_DEVICES += netgear_r7500v2 define Device/netgear_r7800 $(call Device/DniImage) DEVICE_DTS := qcom-ipq8065-r7800 - KERNEL_SIZE := 2097152 + KERNEL_SIZE := 4194304 NETGEAR_BOARD_ID := R7800 NETGEAR_HW_ID := 29764958+0+128+512+4x4+4x4+cascade BLOCKSIZE := 128k -- cgit v1.2.3
