FLASH secure boot address 0 register
| BOOT_LOCK | Boot lock This lock is only used when TZEN = 0. 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 regression level 1 to level 0. |
| SECBOOTADD0 | Secure boot base address 0 This address is only used when TZEN = 1. The secure boot memory address can be programmed to any address in the valid address range (see Table28: Boot space versus RDP protection) 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 user Flash memory (0x0C00 0000) SECBOOTADD0[24:0] = 0x01F F000: Boot from RSS system Flash memory (0x0FF8 0000) SECBOOTADD0[24:0] = 0x060 0000: Boot from secure SRAM1 on S-Bus (0x3000 0000) |
