Kinetis flash memory can be defined in different sizes and supported sizes are 32, 64, 128,
256, 512 and 1024 KBytes.
#define KINETIS_FLASH FLASH_512K
Following define determines if the bootloader code will be protected or not (protection is
recommended). First section of the flash will be protected (protected_size = flash_size / 32).
protection enabled - 1 , protection disabled - 0
#define BOOTLOADER_FLASH_PROTECTION 1
Flash write access allows change mode of access to flash memory. Each model of MCU can support
different write access. Supported write access macros are defined as follows:
FLASH_WRITE_ACCESS_LONG - 32 Bytes
FLASH_WRITE_ACCESS_PHRASES - 64 Bytes
FLASH_WRITE_ACCESS_DOUBLE_PHRASES - 128 Bytes
#define FLASH_WRITE_ACCESS FLASH_WRITE_ACCESS_PHRASES
Address of base pointer to actual used UART module
#define BOOT_UART_MODULE UART2_BASE_PTR
Range of UART baudrates is between (9600 - 115200 Baud)
#define BOOT_UART_BAUD_RATE 115200
Address of peripheral base pointer for GPIO port (number of GPIO port shared with UART module)
#define BOOT_UART_GPIO_PORT PORTE_BASE_PTR
Setting of multiplexer for UART alternative of the pin
#define BOOT_PIN_UART_ALTERNATIVE 3
Setting of multiplexer for GPIO alternative of the pin
#define BOOT_PIN_GPIO_ALTERNATIVE 1
