Description

FLASH secure boot address 0 register

Fields

BOOT_LOCK

Boot lock When set, the boot is always forced to base address value programmed in SECBOOTADD0[24:0] option bytes whatever the boot selection option. When set, this bit can only be cleared by an RDP at level 0.

SECBOOTADD0

Secure boot base address 0 The secure boot memory address can be programmed to any address in the valid address range with a granularity of 128 bytes. This bits correspond to address [31:7] The SECBOOTADD0 option bytes are selected following the BOOT0 pin or nSWBOOT0 state. Examples: SECBOOTADD0[24:0] = 0x018 0000: Boot from secure Flash memory (0x0C00 0000) SECBOOTADD0[24:0] = 0x01F F000: Boot from RSS (0x0FF8 0000) SECBOOTADD0[24:0] = 0x060 0000: Boot from secure SRAM1 on S-Bus (0x3000 0000)
