From c228bbe616a52921a9d8fc961b3efcbdd3880c25 Mon Sep 17 00:00:00 2001 From: Stefan Lippers-Hollmann Date: Fri, 18 May 2018 04:12:04 +0200 Subject: [PATCH] ipq806x: increase kernel partition size for the Netgear Nighthawk X4 R7500 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 change follows the functional example of the Netgear r7800, but has not been runtime tested on a Netgear Nighthawk X4 R7500 Signed-off-by: Stefan Lippers-Hollmann Cc: Jonas Gorski --- .../files-4.14/arch/arm/boot/dts/qcom-ipq8064-r7500.dts | 6 +++--- .../files-4.9/arch/arm/boot/dts/qcom-ipq8064-r7500.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-ipq8064-r7500.dts b/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8064-r7500.dts index 3445a79251..84d79a07f0 100644 --- a/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8064-r7500.dts +++ b/target/linux/ipq806x/files-4.14/arch/arm/boot/dts/qcom-ipq8064-r7500.dts @@ -216,12 +216,12 @@ kernel@1340000 { label = "kernel"; - reg = <0x1340000 0x0200000>; + reg = <0x1340000 0x0400000>; }; - ubi@1540000 { + ubi@1740000 { label = "ubi"; - reg = <0x1540000 0x1800000>; + reg = <0x1740000 0x1600000>; }; netgear@2d40000 { diff --git a/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8064-r7500.dts b/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8064-r7500.dts index 3445a79251..84d79a07f0 100644 --- a/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8064-r7500.dts +++ b/target/linux/ipq806x/files-4.9/arch/arm/boot/dts/qcom-ipq8064-r7500.dts @@ -216,12 +216,12 @@ kernel@1340000 { label = "kernel"; - reg = <0x1340000 0x0200000>; + reg = <0x1340000 0x0400000>; }; - ubi@1540000 { + ubi@1740000 { label = "ubi"; - reg = <0x1540000 0x1800000>; + reg = <0x1740000 0x1600000>; }; netgear@2d40000 { diff --git a/target/linux/ipq806x/image/Makefile b/target/linux/ipq806x/image/Makefile index 496564de38..5a1faa3ead 100644 --- a/target/linux/ipq806x/image/Makefile +++ b/target/linux/ipq806x/image/Makefile @@ -119,7 +119,7 @@ TARGET_DEVICES += netgear_d7800 define Device/netgear_r7500 $(call Device/DniImage) DEVICE_DTS := qcom-ipq8064-r7500 - KERNEL_SIZE := 2097152 + KERNEL_SIZE := 4194304 NETGEAR_BOARD_ID := R7500 NETGEAR_HW_ID := 29764841+0+128+256+3x3+4x4 BLOCKSIZE := 128k
