Greetings,

I need help related to UT porting to new device. I am not kernel dev and I struggling for 2nd week.


I followed the porting guide, I am able to build and boot the kernel.
Stuck with some mount/partition problems...

My goal is Inforce Computing IFC6410 MSM8960 dev.board.
I have working Android 4.1 kernel from IFC and also Nexus4 (mako) device and build to compare to.

I see mounting errors during boot.
[    6.175919] initrd: mounting /dev/mmcblk0p13
[    6.185106] EXT3-fs (mmcblk0p13): error: couldn't mount because of unsupported optional features (40)
[    6.252159] EXT2-fs (mmcblk0p13): error: couldn't mount because of unsupported optional features (44)
[    6.343262] EXT4-fs (mmcblk0p13): recovery complete
[    6.348084] EXT4-fs (mmcblk0p13): mounted filesystem with ordered data mode. Opts: (null)
[    6.356233] initrd: Couldn't find a system partition.
Couldn't find a system partition. Spawning adbd ...


Luckily I can do adb shell - and I see only initrd barebone system.


p13 is userdata.img. For some reason the image smaller than I'd expect.

Initially I used same partitions as Android but noticed system and usr are too small so I tried to bump them.

Here is related part of BoardConfig:

BOARD_KERNEL_CMDLINE := console=ttyHSL0,115200,n8 androidboot.hardware=msm8960

BOARD_MKBOOTIMG_ARGS := --ramdisk_offset 0x01600000

BOARD_TOMBSTONESIMAGE_PARTITION_SIZE := 268435456
BOARD_FLASH_BLOCK_SIZE := 131072 # (BOARD_KERNEL_PAGESIZE * 64)

BOARD_USES_SECURE_SERVICES := true


Any help is appreciated.


Thanks
