Set Breakpoints in arm-elf-gdb

Breakpoints allow you to run your program up to a desired point.

Set Breakpoint

In arm-elf-gdb, to set a breakpoint use the break command, which can be abbreviated to just b, followed by a label, address, or line number in the .s file. 

Examples

break _start

b main

b 0x8004

b 17 (set breakpoint at line 17 of the original assembly file)

Check Breakpoints

To find all breakpoints, type info breakpoint. Again, abbreviations can be used to execute the equivalent i b

Run Until Breakpoint is Reached

The command continue will run the program until the next breakpoint. c will perform the same function.
