SPDX-License-Identifier: GPL-2.0+: load command ============ Synopsis -------- :: load [ [ [ [bytes [pos]]]]] Description ----------- The load command is used to read a file from a filesystem into memory. The number of transferred bytes is saved in the environment variable filesize. The load address is saved in the environment variable fileaddr. interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number, defaults to 0 (whole device) addr load address, defaults to environment variable loadaddr or if loadaddr is not set to configuration variable CONFIG_SYS_LOAD_ADDR filename path to file, defaults to environment variable bootfile bytes maximum number of bytes to load pos number of bytes to skip part, addr, bytes, pos are hexadecimal numbers. Example ------- :: => load mmc 0:1 ${kernel_addr_r} snp.efi 149280 bytes read in 11 ms (12.9 MiB/s) => => load mmc 0:1 ${kernel_addr_r} snp.efi 1000000 149280 bytes read in 9 ms (15.8 MiB/s) => => load mmc 0:1 ${kernel_addr_r} snp.efi 1000000 100 149024 bytes read in 10 ms (14.2 MiB/s) => => load mmc 0:1 ${kernel_addr_r} snp.efi 10 16 bytes read in 1 ms (15.6 KiB/s) => Configuration ------------- The load command is only available if CONFIG_CMD_FS_GENERIC=y. Return value ------------ The return value $? is set to 0 (true) if the file was successfully loaded even if the number of bytes is less then the specified length. If an error occurs, the return value $? is set to 1 (false).
