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.
