.. SPDX-License-Identifier: GPL-2.0+: seama command ============= Synopsis -------- :: seama 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.
