Breakpoints/debug inside assembler source files

[AlexF]

I fixed it.
In my case, I use some sections of flash.

Exsample:

  .syntax unified
  .arch armv7-m
  .thumb
  .thumb_func
//  .section .fixedcode
//---------------------------------
// mcpy
//---------------------------------
  .align  4
  .globl  mcpy
  .type    mcpy, %function

mcpy:
  cmp  R2,#4
  blo  mcpy_last_bytes
  ldr  R3,[R1],#4
  str  R3,[R0],#4
  subs  R2,#4
  b    mcpy
mcpy_last_bytes:
  cbz  R2,mcpy_finish
  ldrb  R3,[R1],#1
  strb  R3,[R0],#1
  subs  R2,#1
  b    mcpy_last_bytes
mcpy_finish:
  bx    lr

If uncomment the line //  .section .fixedcode the debug not work in this source file

linker script:

SECTIONS
{
.text :
{
KEEP(*(.isr_vector))
KEEP(*(.fixedcode))
. = 0x4000;
KEEP(*(.calltable))
. = 0x4100;
*(.text*)
*(.rodata*)
} > ROM
