2) Start the NuttX build at least one time from the Cygwin command line
|
||||
before trying to create your project. This is necessary to create
|
||||
certain auto-generated files and directories that will be needed.
|
||||
3) Set up include pathes: You will need include/, arch/arm/src/lm3s,
|
||||
arch/arm/src/common, arch/arm/src/cortexm3, and sched/.
|

3) Set up include pathes: You will need include/, arch/avr/src/at91uc3,
|
||||
arch/avr/src/common, arch/arm/src/avr, and sched/.
|
||||
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
||||
on the command line.
|
||||
|
||||
Startup files will probably cause you some headaches. The NuttX startup file
|
||||
is arch/arm/src/lm3s/lm3s_vectors.S.
|
||||
is arch/avr/src/avr3/up_nommuhead.S.

||||
|
||||
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
