boot_config - 2024.2 English

Syntax

boot_config { <options> }

Description

This attribute specifies the parameters that are used to configure the bootimage. The options are:

• bh_auth_enable: Boot Header authentication enable, authenticating the bootimage while excluding the verification of PPK hash and SPK ID.
• pufhd_bh: PUF helper data is stored in boot header (default is efuse). PUF helper data file is passed to Bootgen using the option puf_file.
• puf4kmode: PUF is tuned to use in 4 k bit syndrome configuration (Default is 12 k bit).
• shutter = <value>: 32-bit PUF_SHUT register value to configure PUF for shutter offset time and shutter open time.
• smap_width = <value>: Defines the SelectMAP (SMAP) bus width.

  Options are:

  • 8,16, 32 for monolithic/Master SLR (with default 32-bit)
  • 0 for SSI technology Slave SLRs only
  Note: SSI technology Slave SLRs is set to smap_width=0 to indicate the internal downstream connection. This option value must not be changed and is only applicable for SSI technology Slave SLRs.
• dpacm_enable: DPA Counter Measure Enable
• a_hwrot: Asymmetric hardware root of trust (A-HWRoT) boot mode. Bootgen checks against the design rules for A-HWRoT boot mode. Valid only for production PDIs.
• s_hwrot: Asymmetric hardware root of trust (S-HWRoT) boot mode. Bootgen checks against the design rules for S-HWRoT boot mode. Valid only for production PDIs.
