From 412763c81204d0fda0ebb753cb1da78aada34c5b Mon Sep 17 00:00:00 2001 From: Luis Araneda Date: Mon, 3 Sep 2018 22:40:02 -0300 Subject: zynq: add sdcard image support Implement the generation of sdcard images with ext4 or squashfs + f2fs overlay, but only enable the latter automatically Additionally, add mkf2fs and e2fsprogs to default packages to manipulate ext4 and f2fs filesystems Finally, disable the automatic generation of initramfs and rootfs.tar.gz images, as they are no longer required (they can still be selected in menuconfig) Signed-off-by: Luis Araneda --- target/linux/zynq/Makefile | 4 ++-- target/linux/zynq/image/Makefile | 20 ++++++++++++++++++++ target/linux/zynq/image/gen_zynq_sdcard_img.sh | 26 ++++++++++++++++++++++++++ 3 files changed, 48 insertions(+), 2 deletions(-) create mode 100755 target/linux/zynq/image/gen_zynq_sdcard_img.sh (limited to 'target/linux/zynq') diff --git a/target/linux/zynq/Makefile b/target/linux/zynq/Makefile index 6c0ca921d5..6193675088 100644 --- a/target/linux/zynq/Makefile +++ b/target/linux/zynq/Makefile @@ -9,7 +9,7 @@ include $(TOPDIR)/rules.mk ARCH:=arm BOARD:=zynq BOARDNAME:=Xilinx Zynq 7000 SoCs -FEATURES:=fpu gpio rtc usb usbgadget ramdisk targz +FEATURES:=fpu gpio rtc usb usbgadget boot-part rootfs-part squashfs CPU_TYPE:=cortex-a9 CPU_SUBTYPE:=neon MAINTAINER:=Jason Wu @@ -26,6 +26,6 @@ include $(INCLUDE_DIR)/target.mk KERNELNAME:=Image dtbs -DEFAULT_PACKAGES += uboot-envtools +DEFAULT_PACKAGES += uboot-envtools mkf2fs e2fsprogs $(eval $(call BuildTarget)) diff --git a/target/linux/zynq/image/Makefile b/target/linux/zynq/image/Makefile index aa98f4bf3b..92174db19a 100644 --- a/target/linux/zynq/image/Makefile +++ b/target/linux/zynq/image/Makefile @@ -7,6 +7,24 @@ include $(TOPDIR)/rules.mk include $(INCLUDE_DIR)/image.mk +FAT32_BLOCK_SIZE=1024 +FAT32_BLOCKS=$(shell echo $$(($(CONFIG_TARGET_KERNEL_PARTSIZE)*1024*1024/$(FAT32_BLOCK_SIZE)))) + +define Build/zynq-sdcard + rm -f $@.boot + mkfs.fat $@.boot -C $(FAT32_BLOCKS) + mcopy -i $@.boot $(STAGING_DIR_IMAGE)/$(DEVICE_NAME)-boot.bin ::boot.bin + mcopy -i $@.boot $(STAGING_DIR_IMAGE)/$(DEVICE_NAME)-u-boot.img ::u-boot.img + mcopy -i $@.boot $(STAGING_DIR_IMAGE)/$(DEVICE_NAME)-uEnv.txt ::uEnv.txt + mcopy -i $@.boot $(IMAGE_KERNEL) ::fit.itb + ./gen_zynq_sdcard_img.sh $@ \ + $@.boot \ + $(IMAGE_ROOTFS) \ + $(CONFIG_TARGET_KERNEL_PARTSIZE) \ + $(CONFIG_TARGET_ROOTFS_PARTSIZE) + rm -f $@.boot +endef + ################################################# # Default and templates ################################################# @@ -17,6 +35,8 @@ define Device/Default KERNEL_INITRAMFS_PREFIX := $$(IMG_PREFIX)-$(1)-initramfs KERNEL_PREFIX := $$(IMAGE_PREFIX) KERNEL_LOADADDR := 0x8000 + IMAGES := sdcard.img.gz + IMAGE/sdcard.img.gz := zynq-sdcard | gzip endef define Device/FitImageGzip diff --git a/target/linux/zynq/image/gen_zynq_sdcard_img.sh b/target/linux/zynq/image/gen_zynq_sdcard_img.sh new file mode 100755 index 0000000000..460a336e69 --- /dev/null +++ b/target/linux/zynq/image/gen_zynq_sdcard_img.sh @@ -0,0 +1,26 @@ +#!/usr/bin/env bash + +set -ex +[ $# -eq 5 ] || { + echo "SYNTAX: $0 " + exit 1 +} + +OUTPUT="$1" +BOOTFS="$2" +ROOTFS="$3" +BOOTFSSIZE="$4" +ROOTFSSIZE="$5" + +head=4 +sect=63 + +set $(ptgen -o $OUTPUT -h $head -s $sect -l 1024 -t c -p ${BOOTFSSIZE}M -t 83 -p ${ROOTFSSIZE}M) + +BOOTOFFSET="$(($1 / 512))" +BOOTSIZE="$(($2 / 512))" +ROOTFSOFFSET="$(($3 / 512))" +ROOTFSSIZE="$(($4 / 512))" + +dd bs=512 if="$BOOTFS" of="$OUTPUT" seek="$BOOTOFFSET" conv=notrunc +dd bs=512 if="$ROOTFS" of="$OUTPUT" seek="$ROOTFSOFFSET" conv=notrunc -- cgit v1.2.3
