| #define | NRF_UICR_BOOTLOADER_START_ADDRESS (NRF_UICR_BASE + 0x14) |
| Macro for getting the start address of the bootloader image. More... | |
| #define | SD_INFO_ABS_OFFSET_GET(baseaddr, offset) ((baseaddr) + (SOFTDEVICE_INFO_STRUCT_OFFSET) + (offset)) |
| Macro for converting an offset inside the SoftDevice information struct to an absolute address. | |
| #define | SD_OFFSET_GET_UINT32(baseaddr, offset) (*((uint32_t *) SD_INFO_ABS_OFFSET_GET(baseaddr, offset))) |
| Macros for reading a byte or a word at a particular offset inside a SoftDevice information struct. Use MBR_SIZE as baseaddr when the SoftDevice is installed just above the MBR (the usual case). | |
| #define | SD_OFFSET_GET_UINT16(baseaddr, offset) (*((uint16_t *) SD_INFO_ABS_OFFSET_GET(baseaddr, offset))) |
| #define | SD_OFFSET_GET_UINT8(baseaddr, offset) (*((uint8_t *) SD_INFO_ABS_OFFSET_GET(baseaddr, offset))) |
| #define | SD_MAGIC_NUMBER_GET(baseaddr) SD_OFFSET_GET_UINT32(baseaddr, 0x04) |
| Macro for reading the magic number of a SoftDevice at a given base address. | |
| #define | SD_MAGIC_NUMBER_ABS_OFFSET_GET(baseaddr) SD_INFO_ABS_OFFSET_GET(baseaddr, 0x04) |
| Macro for getting the absolute address of the magic number. | |
| #define | SD_MAGIC_NUMBER ((uint32_t)0x51B1E5DB) |
| The number present at a specific location in all SoftDevices. | |
| #define | SD_PRESENT ((SD_MAGIC_NUMBER_GET(MBR_SIZE)) == (SD_MAGIC_NUMBER)) |
| Whether a SoftDevice is at its regular location. | |
| #define | SD_MAJOR_VERSION_MULTIPLIER (1000000) |
| The multiplier for the major version of the SoftDevice. See SD_VERSION_GET. | |
| #define | SD_MAJOR_VERSION_EXTRACT(raw_version) ((raw_version)/SD_MAJOR_VERSION_MULTIPLIER) |
| Read the major version of the SoftDevice from the raw version number. See SD_VERSION_GET. | |

| #define BOOTLOADER_DFU_GPREGRET2_MASK (0xA8) |
Magic pattern written to GPREGRET2 register to signal between main app and DFU. The 3 lower bits are assumed to be used for signalling purposes.
| #define BOOTLOADER_DFU_GPREGRET_MASK (0xB0) |
Magic pattern written to GPREGRET register to signal between main app and DFU. The 3 lower bits are assumed to be used for signalling purposes.
| #define BOOTLOADER_DFU_SKIP_CRC (BOOTLOADER_DFU_GPREGRET2_MASK | BOOTLOADER_DFU_SKIP_CRC_BIT_MASK) |
Magic number to signal that CRC can be skipped due to low power modes.
| #define BOOTLOADER_DFU_SKIP_CRC_BIT_MASK (0x01) |
Bit mask to signal from main application that CRC-check is not needed for image verification.
| #define BOOTLOADER_DFU_START (BOOTLOADER_DFU_GPREGRET_MASK | BOOTLOADER_DFU_START_BIT_MASK) |
Magic number to signal that bootloader should enter DFU mode because of signal from Buttonless DFU in main app.
| #define BOOTLOADER_DFU_START_BIT_MASK (0x01) |
Bit mask to signal from main application to enter DFU mode using a buttonless service.
| #define NRF_UICR_BOOTLOADER_START_ADDRESS (NRF_UICR_BASE + 0x14) |
Macro for getting the start address of the bootloader image.
The macro is not a compile time symbol. It cannot be used as a constant expression, for example, inside a static assert or linker script at-placement.Macro for getting the size of the bootloader image. Bootloader start address in UICR.
Register location in UICR where the bootloader start address is stored.
