2) Start the NuttX build at least one time from the Cygwin command line

certain auto-generated files and directories that will be needed.

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
