Hi, perhaps I am overseeing a simple solution for my problem:
On the pic32 there are two flash areas, one at 0x9d000000 for the main
program and another at 0xbfc00000 that is called Boot Flash. On reset
the program starts in the boot flash at the first address.
I have written the startup code for the chips now but I need to
distribute some procedures between the two memory areas, for obvious
reasons I must have some code at address 0xbfc00000 or the chip will
not boot correctly ;-).
My thought was now to tweak the linker script in the same way the
original linker scripts of pic32 work:
MEMORY
{
kseg0_program_mem (rx) : ORIGIN = 0x9D000000, LENGTH = 0x80000
kseg1_boot_mem : ORIGIN = 0xBFC00000, LENGTH = 0x490
}
SECTIONS
{
.reset _RESET_ADDR :
{
KEEP(*(.reset))
KEEP(*(.reset.startup))
} > kseg1_boot_mem
}
In assembler I can then simply write:
.section .reset,code and
.section .reset.startup,code
and then the code, this will automagically end up in the
kseg1_boot_mem, but this does not work with the inline assembler. Any
ideas on how to do this the correct way? Is there something more
intelligent than to write a plain assembler file?
TnX,
Michael
You should be able to use
.section ".reset"
