Which board needs it? It's quite unusual to have this on arm64... The ubifs settings is enabled for Agilex and Stratix10 socfpga platform with rootfs mounted from QSPI NOR. > >>> > >>> Signed-off-by: Alif Zakuan Yuslaimi <alif.zakuan.yuslaimi@intel.com> > >>> Signed-off-by: Kah Jing Lee <kah.jing.lee@intel.com> > >>> --- > >>> arch/arm64/configs/defconfig | 2 ++ > >>> 1 file changed, 2 insertions(+) > >>> > >>> diff --git a/arch/arm64/configs/defconfig > >>> b/arch/arm64/configs/defconfig index a24609e14d50..23a6ebcb1a9e > >> 100644 > >>> --- a/arch/arm64/configs/defconfig > >>> +++ b/arch/arm64/configs/defconfig > >>> @@ -470,6 +470,8 @@ CONFIG_IPMI_DEVICE_INTERFACE=m > >> CONFIG_IPMI_SI=m > >>> CONFIG_HW_RANDOM=y CONFIG_HW_RANDOM_VIRTIO=y > >>> +CONFIG_MTD_UBI=y > >>> +CONFIG_UBIFS_FS=y > >> > >> Not modules? > > Yes, we need to boot with rootfs with UBIFS. > > So you miss init ramdisk. Currently we are using the bootargs to mount the rootfs from QSPI NOR flash: [ 0.000000] Kernel command line: earlycon panic=-1 ubi.mtd=1 root=ubi0:rootfs rootfstype=ubifs rw rootwait Is it possible to mount the ubifs rootfs with the ubifs=m config during boot?
