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

|
||
|
|
is set to 1 (false) in case of error.
|
||
|
|
|

|
The environment variable $seama_image_size is set to the size of the
|
||
|
|
loaded SEAMA image.
