Syntax
[fsbl_config <options>] <partition>
Description
This option specifies the parameters used to configure the boot image. FSBL, which should run on A53 in 64-bit mode in Boot Header authentication mode.
Arguments
-
bh_auth_enable
: Boot Header Authentication Enable: RSA authentication of the bootimage is done excluding the verification of PPK hash and SPK ID. -
auth_only
: Boot image is only RSA signed. FSBL should not be decrypted. See the Zynq UltraScale+ Device Technical Reference Manual (UG1085) for more information. -
opt_key
: Operational key is used for block-0 decryption. Secure Header has the opt key. -
pufhd_bh
: PUF helper data is stored in Boot Header (default isefuse
). PUF helper data file is passed to Bootgen using the[puf_file]
option. -
puf4kmode
: PUF is tuned to use in 4 k bit configuration (default is 12 k bit). -
shutter = <value>
: 32-bitPUF_SHUT
register value to configure PUF for shutter offset time and shutter open time.Note: This shutter value must match the shutter value that was used during PUF registration.
