Device Firmware Update module type and definitions.
#define BOOTLOADER_REGION_START 0x0003C000 |
This field should correspond to start address of the bootloader, found in UICR.RESERVED, 0x10001014, register. This value is used for sanity check, so the bootloader will fail immediately if this value differs from runtime value. The value is used to determine max application size for updating.
#define BOOTLOADER_SETTINGS_ADDRESS 0x0003FC00 |
The field specifies the page location of the bootloader settings address.
#define CODE_PAGE_SIZE 0x0400 |
Size of a flash codepage. Used for size of the reserved flash space in the bootloader region. Will be runtime checked against NRF_UICR->CODEPAGESIZE to ensure the region is correct.
#define CODE_REGION_1_START SOFTDEVICE_INFORMATION->softdevice_size |
This field should correspond to the size of Code Region 0, (which is identical to Start of Code Region 1), found in UICR.CLEN0 register. This value is used for compile safety, as the linker will fail if application expands into bootloader. Runtime, the bootloader will use the value found in UICR.CLEN0.
#define DATA_PACKET 0x04 |
Packet identifies for a Data Packet.
#define DFU_APP_DATA_RESERVED 0x0000 |
Size of Application Data that must be preserved between application updates. This value must be a multiple of page size. Page size is 0x400 (1024d) bytes, thus this value must be 0x0000, 0x0400, 0x0800, 0x0C00, 0x1000, etc.
#define DFU_BANK_0_REGION_START CODE_REGION_1_START |
Bank 0 region start.
#define DFU_BANK_1_REGION_START (DFU_BANK_0_REGION_START + DFU_IMAGE_MAX_SIZE_BANKED) |
Bank 1 region start.
#define DFU_BL_IMAGE_MAX_SIZE (BOOTLOADER_SETTINGS_ADDRESS - BOOTLOADER_REGION_START) |
Maximum size of a bootloader, excluding save data from the current bootloader.
#define DFU_IMAGE_MAX_SIZE_BANKED (((DFU_REGION_TOTAL_SIZE)/2) - DFU_APP_DATA_RESERVED) |
Maximum size of a application, excluding save data from the application.
#define DFU_IMAGE_MAX_SIZE_FULL (DFU_REGION_TOTAL_SIZE - DFU_APP_DATA_RESERVED) |
Maximum size of a application, excluding save data from the application.
#define DFU_INIT_COMPLETE 0x01 |
Op Code identifies for transmission complete of init packet.
#define DFU_INIT_RX 0x00 |
Op Code identifies for receiving init packet.
#define DFU_REGION_TOTAL_SIZE (BOOTLOADER_REGION_START - CODE_REGION_1_START) |
Total size of the region between SD and Bootloader.
#define DFU_UPDATE_APP 0x04 |
Bit field indicating update of application is ongoing.
#define DFU_UPDATE_BL 0x02 |
Bit field indicating update of bootloader is ongoing.
#define DFU_UPDATE_SD 0x01 |
Bit field indicating update of SoftDevice is ongoing.
#define EMPTY_FLASH_MASK 0xFFFFFFFF |
Bit mask that defines an empty address in flash.
#define INIT_PACKET 0x01 |
Packet identifies for initialization packet.
#define INVALID_PACKET 0x00 |
Invalid packet identifies.
#define NRF_UICR_BOOT_START_ADDRESS (NRF_UICR_BASE + 0x14) |
Register where the bootloader start address is stored in the UICR register.
#define SOFTDEVICE_INFORMATION ((SOFTDEVICE_INFORMATION_Type *) SOFTDEVICE_INFORMATION_BASE) |
Make SoftDevice information accessible through the structure.
#define SOFTDEVICE_INFORMATION_BASE 0x0003000 |
Location in the SoftDevice image which holds the SoftDevice informations.
#define SOFTDEVICE_REGION_START 0x00001000 |
This field should correspond to start address of the bootloader, found in UICR.RESERVED, 0x10001014, register. This value is used for sanity check, so the bootloader will fail immediately if this value differs from runtime value. The value is used to determine max application size for updating.
#define START_PACKET 0x03 |
Packet identifies for the Data Start Packet.
#define STOP_DATA_PACKET 0x05 |
Packet identifies for the Data Stop Packet.
#define STOP_INIT_PACKET 0x02 |
Packet identifies for stop initialization packet. Used when complete init packet has been received so that the init packet can be used for pre validaiton.
