[U-Boot] What mkimage arguments for standalone AVR32 app?

[U-Boot] What mkimage arguments for standalone AVR32 app?

[Jesper Vestergaard]

Hi list

I'm trying to create a standalone application for the ICnova ap7000 Base 
and have compiled this little application:


#include <avr32/io.h>

int main( void )
{
  __asm__("nop\n\t""nop\n\t""nop\n\t""nop\n\t");

 while(1)
   {
      ;

   }

   return 0;
}


To create the header file for it I use this mkimage command:

mkimage -A avr32 -O u-boot -T standalone -C none -a 0x11000000 -e 
0x11000000 -n "myapp" -d test.bin test_uboot.bin

but when i try to execute it i get this error:

the entry/load addresses need to match reality.  you cant pick them out of the 
air without properly setting them everywhere.

you also didnt say how you compiled/linked the standalone code ... you must be 
sure to not use any files/libraries/toolchain that expect an operating system 
(like Linux).

you shoulud not load (tftp) the bootable image to the same address that it 
will be uncompressing to (load address).

really you should read doc/README.standalone and the simple examples in 
examples/ instead of trying random commands.

Here's how i compiled it:
avr32-gcc -O2 -Wall -c -fmessage-length=0 -mpart=ap7000 
-ffunction-sections -o test.o test.c
avr32-ld test.o -e 0x00000000 -T simple.lds -o test.out
avr32-objcopy -O binary test.out test.bin

And the simple.lds:
SECTIONS
{
  . = 0x11000000;
  /*. = 0x00000000; */
  .text : { *(.text) }
  /* . = 0x8000000; */
  .data : { *(.data) }
  .bss : { *(.bss) }
}

and a objectdump:

avr32-objdump -d test.out

test.out:     file format elf32-avr32

Disassembly of section .text.main:

11000000 <main>:
11000000:    d7 03           nop
11000002:    d7 03           nop
11000004:    d7 03           nop
11000006:    d7 03           nop
11000008:    c0 08           rjmp    11000008 <main+0x8>

According to the Makefile in the example directory i should load the 
binary to 0x00000000
    ifeq ($(ARCH),avr32)
    LOAD_ADDR = 0x00000000
    endif
but looking at the uboot startup it says that the flash is placed at 
that address and that the SDRAM is placed at 0x10000000.
Flash:  8 MB at address 0x00000000
SDRAM: 64 MB at address 0x10000000

Which of the addresses should i use?

I couldn't find any documentation about what entry address i should use 
for the avr32 but according to the README.standalone it is only the 
power pc which needs a entry address different from the load address so 
i guess load address=entry address.

someone who actually knows/uses AVR32 will have to answer
