Static definitions of the application. More...

#include <bootloader_hal.h>

Public Attributes
uint32_t	app_size
	The total length of the application binary.
uint32_t	checksum_pre [CHECKSUM_COUNT]
	Checksum data for the application info.
uint32_t	checksum_post [CHECKSUM_COUNT]
	checksum_post: is the checksum of the bytes between the app_header and the application end.

Detailed Description

Static definitions of the application.

These will be flashed with the application, and contain checksum on whether the application is valid or not.

Member Data Documentation

app_size

uint32_t app_header::app_size

The total length of the application binary.

The start of the application binary is always at flash_min of get_flash_info. This number tells how many bytes need to be checksummed.

Definition at line 59 of file bootloader_hal.h.

checksum_post

uint32_t app_header::checksum_post[CHECKSUM_COUNT]

checksum_post: is the checksum of the bytes between the app_header and the application end.

Definition at line 70 of file bootloader_hal.h.

checksum_pre

uint32_t app_header::checksum_pre[CHECKSUM_COUNT]

Checksum data for the application info.

The checksumming algorithm is not fixed – the HAL should provide it in case there is hardware CRC support. Unused entries should be filled with zeros.

checksum_pre: is the checksum of the bytes between application_start and the app_header.
