Description
|
|
-----------
|
|
|
|
The seama command is used to load and decode SEAttle iMAges from NAND
|
|
flash to memory.
|
|
|
|
This type of flash image is found in some D-Link routers such as
|
|
DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L, DIR890L and DCH-M225,
|
|
as well as in WD and NEC routers on the ath79 (MIPS), Broadcom
|
|
BCM53xx, and RAMIPS platforms.
|
|
|
|
This U-Boot command will read and decode a SEAMA image from raw NAND
|
|
flash on any platform. As it is always using big endian format for
|
|
the data decoding is always necessary on platforms such as ARM.
|
|
|
|
dst_addr
|
|
destination address of the byte stream to be loaded
|
|
|
|
index
|
|
the image index (0, 1, 2..) can be omitted

::
|
|
|
|
=> seama 0x01000000

SEMA IMAGE:
|
|
metadata size 36
|
|
image size 8781764
|
|
checksum 054859cfb1487b59befda98824e09dd6
|
|
Decoding SEAMA image 0x01000040..0x01860004 to 0x01000000

Configuration
|
|
-------------
|
|
|
|
The command is available if CONFIG_CMD_SEAMA=y.
|
|
|
|
Return value
|
|
------------
|
|
|
|
Along with the general rules for setting $?, the environment variable
|
|
$seama_image_size is set to the size of the loaded SEAMA image.
