sdk

=> sdk
sdk - Broadcom SDK support commands

Usage:
sdk
force
 - Without arguments, display if forced image updates are enabled
force [force value] <[Boot Flash Type] [Image Flash Type]>
 - Enable(value=1)/Disable(value=0) forced image updates. All compatibility checks are ignored if enabled
 - If boot and image flash types are not detected, then they need to be specified as 2nd and 3rd args
 - Valid flash type values = [NAND|SPINAND|EMMC|NOR]
restoredefault
 - Delete contents of /data so that it gets populated with default values
metadata
metadata [committed] [valid],[valid]
 - without arguments, parse and display metadata
 - set metadata values (example "metadata 1 1,2" for both images valid and #1 committed)
 - NOTE: Must do a sw reset for metadata changes to take affect
flash_img_upgrade [-s] <filename> [conf]
flash_img_upgrade [-i] <filename> [<img> [<conf>]]
 - Download and flash an image upgrade bundle via TFTP
 - NOTE: Must do a sw reset to use the new image
load_img [boardid]
load_img [<img> [<boardid>]]
 - Load image from flash into DDR.
boot_img [boardid]
boot_img [<img> [<boardid>]]
 - Boot linux from image in flash.
[Legend - Optional Parameters]
 -s:      Skip downloading the image via tftp. Assume it is already at ${fileaddr}
 -i:      Inactive. Mark new image as inactive i.e do not commit image
 img:     Image index for flashing/booting. Valid values: [1|2]. Default index is determined from metadata
 boardid: Boardid to determine boot configuration. If omitted default configuration node is used
 conf:    Configuration name used for flashing img bundle. If omitted default configuration node is used

httpd_start
 - without arguments, start httpd server
otp set <row> <val> fuses <val> at <row> to OTP . Warning! otp fuse operations are irreverisble
otp get <row>       reads content at <row> from  OTP
otp secure          Achtung!!!!! This command will turn board to MFG boot secure mode.
                    On success the board will be halted and must be power cycled.
