Define Documentation

#define BSS_IRQ   *(.libavr32.bss.irq.*)

Interrupt handler data section.

This section contains the data pointers associated with each interrupt.

Definition at line 89 of file linkerscript.h.

#define LDS_NANOTRACE_SECTION

Value:

.nanotrace (NOLOAD) : {                         \
                KEEP(*(.nanotrace));                    \
                . = ALIGN(8);                           \
        }

NanoTrace buffer section.

When CONFIG_NANOTRACE_SIZE is defined, this will define a .nanotrace section which will contain a buffer to store NanoTrace data when enabled by an external debugger.

When enabled, the start-xxx.S file will define a suitably-sized array called NANOTRACE to be placed in this section.

Definition at line 57 of file linkerscript.h.

#define LDS_STACK_SECTION

Value:

.stack (NOLOAD) : {                             \
                . = . + CONFIG_STACK_SIZE;              \
                . = ALIGN(8);                           \
                _end = .;                               \
        }

The stack section.

This macro must be used at the end of the linker script to reserve room for the stack.

Definition at line 69 of file linkerscript.h.

#define TEXT_IRQ   *(.libavr32.text.irq.*)

Interrupt handler section.

This section contains the low-level interrupt entry points.

Definition at line 81 of file linkerscript.h.

Function Documentation

void _evba

(

void

)

Exception Vector Base Address.

This symbol marks the beginning of the exception handler table.
