| 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. |
