| ============= |
| |
| 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. |
