Function Documentation

flash_crc_check()

FctERR flash_crc_check

(

void

)

Application Flash CRC check.

Note

Assuming flash crc to check against is located in the last 4bytes of application reserved flash

Get_app_start_address & Get_app_size needs to be implemented in project, otherwise acts as flash_crc_check

Return values

ERROR_OK	- Flash CRC consistent
ERROR_CRC	- Flash CRC inconsistent

Here is the call graph for this function:

flash_full_crc_check()

FctERR flash_full_crc_check

(

void

)

Flash CRC check (complete FLASH area)

Note

Assuming flash crc to check against is located in the last 4bytes of flash

Ideal when application takes the whole FLASH area, otherwise use flash_crc_check instead

Return values

ERROR_OK	- Flash CRC consistent
ERROR_CRC	- Flash CRC inconsistent

Here is the call graph for this function:

Get_app_size()

uint32_t Get_app_size

(

void

)

Get Application size.

Weak Functions

Function declared as weak, needs to be customly implemented in user code, otherwise returns FLASH_SIZE value

Returns

Application size

Here is the caller graph for this function:

Get_app_start_address()

uint32_t Get_app_start_address

(

void

)

Get Application start address.

Weak Functions

Function declared as weak, needs to be customly implemented in user code, otherwise returns FLASH_BASE value

Returns
