This patch series adds support for ZFS listing and load to u-boot.
|
|
|
|
To Enable zfs ls and load commands, modify the board specific config file with
|
|
#define CONFIG_CMD_ZFS
|
|
|
|
Steps to test:
|
|
|
|
1. After applying the patch, zfs specific commands can be seen
|
|
in the boot loader prompt using
|
|
UBOOT #help
|
|
|
|
zfsload- load binary file from a ZFS file system
|
|
zfsls - list files in a directory (default /)
|
|
|
|
2. To list the files in zfs pool, device or partition, execute
|
|
zfsls <interface> <dev[:part]> [POOL/@/dir/file]
|
|
For example:
|
|
UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/
|
|
|
|
3. To read and load a file from an ZFS formatted partition to RAM, execute
|
|
zfsload <interface> <dev[:part]> [addr] [filename] [bytes]
|
|
For example:
|
|
UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage
|
|
