riscv-initramfs-image default password

[lyctw]

Hi developers,

I've built riscv-initramfs-image provided by meta-riscv and added the variables in local.conf

INITRAMFS_IMAGE_BUNDLE = "1"
INITRAMFS_IMAGE = "riscv-initramfs-image"
INITRAMFS_IMAGE_NAME = "riscv-initramfs-image-${MACHINE}.rootfs"
BOOT_SPACE = "1073741"
INITRAMFS_MAXSIZE = "315400"
IMAGE_FSTYPES:pn-${INITRAMFS_IMAGE} = "${INITRAMFS_FSTYPES}"

it successfully launched login prompt using busybox init. But it asks password for root, Am I missing something?

I've also checked EXTRA_IMAGE_FEATURES = "debug-tweaks" specified in my local.conf

Can you try this for the bb file

# will be used for the update image
DESCRIPTION = "initramfs updater image"
LICENSE = "MIT"

LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

# Do not pollute the initrd image with rootfs features
IMAGE_FEATURES = ""

# Clear image depends on some machines e.g. riscv opensbi is in EXTRA_IMAGEDEPENDS
# which can cause dependency loops
EXTRA_IMAGEDEPENDS = ""

IMAGE_NAME_SUFFIX = ""

export IMAGE_BASENAME = "riscv-initramfs-image"
IMAGE_LINGUAS = ""

PACKAGE_INSTALL = "\

IMAGE_FSTYPES = "${INITRAMFS_FSTYPES}"
# Check conf/site.conf where there is IMAGE_FSTYPES:append
# if that value changes make the change here as well
IMAGE_FSTYPES:remove = "wic.* wic.xz wic.bmap tar.xz"
inherit core-image

IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt"
IMAGE_ROOTFS_SIZE = "8192"
IMAGE_ROOTFS_EXTRA_SPACE = "0"
BAD_RECOMMENDATIONS += "busybox-syslog busybox-udhcpc"

@kraj, thanks!

Perhaps some more options are needed for busybox - see https://github.com/YoeDistro/yoe-distro/blob/master/sources/meta-yoe/recipes-core/busybox/busybox/yoe_fragment.cfg

You can define busybox_%.bbappend in meta-riscv like this

https://github.com/YoeDistro/yoe-distro/blob/master/sources/meta-yoe/recipes-core/busybox/busybox_%25.bbappend

btw. you only need

INITRAMFS_IMAGE_BUNDLE = "1"
INITRAMFS_IMAGE = "riscv-initramfs-image"

in local.conf
