AVR32 Bootloader
^^^^^^^^^^^^^^^^
The linker scripts (ld.script) assume that you are using the bootloader.
The bootloader resides at 0x8000:0000 and so the ld.script files link
the application to execute after the bootloader at 0x8000:2000. To link
so that NuttX boots directly without using the bootloader, change the
flash definition from:
flash (rxai!w) : ORIGIN = 0x80002000, LENGTH = 256K - 8K
to:
flash (rxai!w) : ORIGIN = 0x80000000, LENGTH = 256K
