If confronted with physical addresses, it will happily erase everything and brick the device. So for the time being pretend these addresses to start at 0x0 while updating all the flash code with proper sanity checks, then come back later and fix the addresses. -- Henryk Plötz 2009-08-27 */ bootphase1 : ORIGIN = 0x00000000, LENGTH = 0x200 /* Phase 1 bootloader: Copies real bootloader to RAM */ bootphase2 : ORIGIN = 0x00000200, LENGTH = 0x2000 - 0x200 /* Main bootloader code, stored in Flash, executed from RAM */ ram : ORIGIN = 0x00200000, LENGTH = 32K } SECTIONS { . = 0; bootphase1 : { *(.startup) *(.bootphase1) } >bootphase1 bootphase2 : { __bootphase2_start__ = .; *(.startphase2) *(.text) *(.glue_7) *(.rodata) *(.data) . = ALIGN( 32 / 8 ); __bootphase2_end__ = .; } >ram AT>bootphase2 .bss : { __bss_start__ = .; *(.bss) } >ram . = ALIGN( 32 / 8 ); __bss_end__ = .; }
