- seama command
- =============
- Synopsis
- --------
- ::
- seama <dst_addr> <index>
- 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
- Example
- -------
- ::
- => seama 0x01000000
- Loading SEAMA image 0 from nand0
- 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
- ------------
- The return value $? is set 0 (true) if the loading is succefull, and
- 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.
