Hints for program debugging

To relate PMA of an executable with the original source code proceed as follows

  1. Execute disjex myprog.jex and find nearest label with corresponding PMA
  2. Execute aobjdump -x -s myprog.elf and search for search in symbol table for a T1000 program memory entry (.tzpm) same address
  3. Search for first preceding symbol referencing a subroutine (hint: grep all lines which contain the string '.tzpm' and sort them according to the address in the first column)
