Hi all,

I'm just starting out in the AVR32 world, after becoming reasonably established in the art of AVR8 programming. Yesterday I received a new EXK1101 board, which I'm now trying to work out how to program. My first goal is to get the board LEDs up and working, so I can move on to other systems.

I'm trying to use only the standalone toolchain, without the AVR32 UC3B framework or AVR32Studio (except for debugging, in the latter case). I'm also trying to modify a standard WinAVR (AVR8) makefile to support compilation to either AVR8 or AVR32 targets.

Note: lengthy fragments follow, but most can be ignored - I'm just trying to give all output to help debug my problem.

This is my current test program:

int main(void)
{
	// External 8MHz+ crystal connected
	AVR32_PM.OSCCTRL0.mode = 7;

	// Startup time 142ms
	AVR32_PM.OSCCTRL0.startup = 6;
	
	// Enable OSC0
	AVR32_PM.MCCTRL.osc0en = true;
	
	// Wait for OSC0 to be ready
	while (!(AVR32_PM.POSCSR.osc0rdy));
	
	// Select OSC0 as the main clock source
	AVR32_PM.MCCTRL.mcsel = 1;

	AVR32_GPIO.port[0].gpers = (1UL << 7);
	AVR32_GPIO.port[0].oders = (1UL << 7);
	AVR32_GPIO.port[0].ovrs  = (1UL << 7);

	for (;;)
	{

	}
}

And my makefile:

#   avr32  =   32-bit AVRs

# LUFA board drivers). If USER is selected, put custom board drivers in a directory called 
# "Board" inside the application directory.
#BOARD  = USBKEY
BOARD = EVK1101

# Processor frequency.
#     This will define a symbol, F_CPU, in all source code files equal to the 
#     processor frequency. You can then use this symbol in your source code to 
#     calculate timings. Do NOT tack on a 'UL' at the end, this will be done
#     automatically to create a 32-bit value in your source code.
#     Typical values are:
#         F_CPU =  1000000
#         F_CPU =  1843200
#         F_CPU =  2000000
#         F_CPU =  3686400
#         F_CPU =  4000000
#         F_CPU =  7372800

#         F_CPU = 18432000
#         F_CPU = 20000000
F_CPU = 8000000


# Input clock frequency.
#     This will define a symbol, F_CLOCK, in all source code files equal to the 
#     input clock frequency (before any prescaling is performed). This value may
#     differ from F_CPU if prescaling is used on the latter, and is required as the
#     raw input clock is fed directly to the PLL sections of the AVR for high speed
#     clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
#     at the end, this will be done automatically to create a 32-bit value in your
#     source code.
#
#     If no clock division is performed on the input clock inside the AVR (via the
#     CPU clock adjust registers or the clock division fuses), this will be equal to F_CPU.

I know the above is long, but I want to be complete. Compiling with the above gives the following output:

And produces a .elf and a .hex file. However, I can't seem to program this into the EVK1101 correctly, as it gives a warning about the flash overlapping the bootloader area:

Does anyone know where my compile/link/program stage is going wrong? I can't seem to find any reference makefiles which I can compare mine to.

Looking forward to experimenting with AVR32s.

Cheers!

OK, the UC3 part comes with a preprogrammed USB bootloader.
Here you have 2 choices:
1/ keep the USB bootloader (user guide here: http://www.atmel.com/dyn/resourc...), your application should be linked at 0x80002000, this is the address the bootloader will launch. That is explaining why you have the "WARNING: The user program and the bootloader overlap! " message.

2/ get rid of the USB bootloader (you can reprogram it later with JTAG), just do "avr32program chiperase" (the bootloader is protected with the BOOTPROT fuse). Your application need to be linked at 0x80000000 (reset vector).

If you look at the software framework code, it comes (in the zip version) with standalone makefile (I likethe "make rebuild program reset run" command). By default, the example are compiled with the trampoline section (trampoline.S linked at 0x80000000-0x80002000), which makes the examples to work either with and without the USB bootloader (in all case the "real" application starts in 0x80002000).
