# 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
# - 1111 "SPI" (run from internal flash)
# - 1110 "USB" (mass storage emulator that accepts a .bin file)
# - 0111 "ICE-SPI" (allow external debugger access, but may not be programmable)
# - 1011 ICP mode (programmable via NuMicro ICP programming tool)

# Flash using Nuvoton's openocd fork at https://github.com/OpenNuvoton/OpenOCD-Nuvoton
# Please compile and install it from github source
