# Note
# To be able to program the SPI flash, it need to boot with ICP mode "1011".
# However, in ICP mode, opencod cannot establish connection to the mcu.
# Therefore, there is no easy command line flash for NUC505
# It is probably better to just use Nuvoton NuMicro ICP programming on windows to program the board

# Flash using Nuvoton's openocd fork at https://github.com/OpenNuvoton/OpenOCD-Nuvoton
