Multiple Firmware Booting
Multiple Firmware Booting
This application note demonstrates how to use XFLASH option --loader to change the behaviour of selecting which image to boot by the flash loader.
This application note provides an example that uses a button to select the image that gets booted. When the button is in the up position at power on, the highest even number image version will be booted. When the button is in the down position at power on, the highest odd number image version will be booted.
