5 Example Usage

The kernel described above is available in the F29H85x MCU SDK at: mcu_sdk_f29h85x/examples/driverlib/single_core/flash/uart_flash_kernel. The host application can be found in the same SDK as well (mcu_sdk_f29h85x /tools/ flash_programmers /uart_flash_programmer). This section details how the kernel and host programmer can be used together to perform firmware upgrades on an F29H85x device.
