22.4.5.15 FLASH_SetCallback
Registers (like to write into a list) expected callback functions into the flash driver, for
example, like a function that services a watchdog.
Prototype:
status_t FLASH_SetCallback(flash_config_t *config, flash_callback_t callback);
Table 22-65. Parameters
Parameter Description
Config Pointer to
flash_config_t
data structure in memory, to store driver runtime state.
Callback A pointer points to a function that is called during erasure.
A use for this function is to service the watchdog during an erase operation.
Table 22-66. Possible status response
Value Constant Description
4 kStatus_InvalidArgument Config or dst pointers are NULL.
115 kStatus_FLASH_CommandNotSupported This function is not supported.
0 kStatus_Success This function has performed successfully.
Example:
Assume that there is a function.
void led_toggle(void).
status_t status = FLASH_SetCallback(&flashInstance, led_toggle);
22.5 Peripherals Supported
This section describes the peripherals supported by the Kinetis ROM Bootloader. To use
an interface for bootloader communications, the peripheral must be enabled in the BCA,
as shown in
Table 22-2 . If the BCA is invalid (such as all 0xFF bytes), then all
peripherals will be enabled by default.
22.5.1 I2C Peripheral
The Kinetis Bootloader in ROM supports loading data into flash via the I2C peripheral,
where the I2C peripheral serves as the I2C slave. A 7-bit slave address is used during the
transfer.
