ubifs编译命令

编译boot.ubifs
./mkfs.ubifs -r boot-image/ -F -o k2hk-evm-boot.ubifs -m 2048 -e 126976 -c 75 

编译rootfs.ubifs
./mkfs.ubifs -r rootfs/  -o tisdk-rootfs.ubifs -m 2048 -e 129024 -c 4129  -F

其中-c 4129  为500MB*1024/124=4129

编译ubifs.ubi
./ubinize -o k2hk-evm-ubifs.ubi -m 2048 -p 128KiB -s 2048 -O 2048 ubinize_k2hk-evm.cfg


ubinize_k2hk-evm.cfg 如下

[boot]
mode=ubi
image=k2hk-evm-boot.ubifs
vol_type=dynamic
vol_id=0
vol_name=boot
vol_size=10MiB
[rootfs]
mode=ubi
image=tisdk-rootfs.ubifs
vol_id=1
vol_size=500MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

编译出来ubifs.ubi有382MB 


		uboot______________________________________________
nand erase.part ubifs
tftpboot 0x60000000 /tftpboot/linux15-08rt/nand-0x60000000/k2hk-evm-ubifs.ubi
nand write 0x60000000 ubifs ${filesize}
因为自己板子DDR3A用不了，只用使用ddrB空间了


执行 run init_ubi

ubifsmount - mount UBIFS volume

Usage:
ubifsmount <volume-name>
    - mount 'volume-name' volume
UBIFS not mounted, use ubifs mount to mount volume first!
ubifsload - load file from an UBIFS filesystem

Usage:
ubifsload <addr> <filename> [bytes]
    - load file 'filename' to address 'addr'
