From mboxrd@z Thu Jan 1 00:00:00 1970 From: Abhimanyu Vishwakarma Date: Tue, 4 Apr 2017 17:18:18 +0530 Subject: [Buildroot] [PATCH v6] Add defconfig for MIPS Creator ci40 Message-ID: <1491306498-18165-1-git-send-email-abhimanyu.v@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net From: Abhimanyu Vishwakarma Add post-image script to generate sdcard.img for preparing sdcard/usb device. Signed-off-by: Abhimanyu Vishwakarma --- Changes v1->v2 - No change Changes v2->v3 (Suggested by Arnout) - Remove uImage and add fitImage generation - Tidy readme.txt - Tidy ci40_defconfig, remove custom toolchain and add wifi helper packages Some changes are not done: - Using git-helper: - Custom kernel doesnt provide tar file, so it didnt work for me Changes v3->v4 (Suggested by Arnout) - Use github helper for getting kernel/u-boot - rename fitImage.its -> fitImage.its.in to reflect as template file, remove hardcoded dtb filename - Find dtb file in output/images directory and use first dtb in fitImage - Remove image size from genimage.cfg - Tidy readme.txt and add section to explain how to stop u-boot autoboot, how to make it persistent, and other grammar Changes v4->v5 (Suggested by Thomas) - Use fixed kernel entry addr - Generate vmlinux.bin.gz from generate vmlinux.bin - Remove generating uImage (not required for anything now) Changes v5->v6 - Use kernel generate fitimage - bump up u-boot version - Change emailid from imgtec.com -> personal id board/ci40/genimage.cfg | 12 +++++++++ board/ci40/post-build.sh | 6 +++++ board/ci40/post-image.sh | 15 +++++++++++ board/ci40/readme.txt | 70 ++++++++++++++++++++++++++++++++++++++++++++++++ configs/ci40_defconfig | 49 +++++++++++++++++++++++++++++++++ 5 files changed, 152 insertions(+) create mode 100644 board/ci40/genimage.cfg create mode 100755 board/ci40/post-build.sh create mode 100755 board/ci40/post-image.sh create mode 100644 board/ci40/readme.txt create mode 100644 configs/ci40_defconfig diff --git a/board/ci40/genimage.cfg b/board/ci40/genimage.cfg new file mode 100644 index 0000000..0ffc91c --- /dev/null +++ b/board/ci40/genimage.cfg @@ -0,0 +1,12 @@ +# Minimal SD card image +# + +image sdcard.img { + hdimage { + } + + partition rootfs { + partition-type = 0x83 + image = "rootfs.ext4" + } +} diff --git a/board/ci40/post-build.sh b/board/ci40/post-build.sh new file mode 100755 index 0000000..0cd06b7 --- /dev/null +++ b/board/ci40/post-build.sh @@ -0,0 +1,6 @@ +#!/bin/bash + +FITIMAGE=$BINARIES_DIR/vmlinux.gz.itb + +# Copy to target +cp -a $FITIMAGE $TARGET_DIR/fitImage diff --git a/board/ci40/post-image.sh b/board/ci40/post-image.sh new file mode 100755 index 0000000..18e76aa --- /dev/null +++ b/board/ci40/post-image.sh @@ -0,0 +1,15 @@ +#!/usr/bin/env bash + +BOARD_DIR="$(dirname $0)" +GENIMAGE_CFG="${BOARD_DIR}/genimage.cfg" +GENIMAGE_TMP="${BUILD_DIR}/genimage.tmp" + +rm -rf "${GENIMAGE_TMP}" + +genimage \ + --rootpath "${TARGET_DIR}" \ + --tmppath "${GENIMAGE_TMP}" \ + --inputpath "${BINARIES_DIR}" \ + --outputpath "${BINARIES_DIR}" \ + --config "${GENIMAGE_CFG}" + diff --git a/board/ci40/readme.txt b/board/ci40/readme.txt new file mode 100644 index 0000000..2fde2b8 --- /dev/null +++ b/board/ci40/readme.txt @@ -0,0 +1,70 @@ +********************* +* MIPS Creator CI40 * +********************* + +The 'ci40_defconfig' will create a root filesystem and a fitImage +under the 'output/images/' directory.

To interrupt autoboot, press any +key before the boot-delay time expires, U-Boot will stops the autoboot process +and gives a U-Boot prompt.
