- Step 16: G/N/Y key table and worked examples (main, stdio_init_all, uart_init,
__wrap_printf); note BN shows int32_t where Ghidra shows int
- Step 26: worked check + pointer to Step 16
- troubleshooting: macOS serial capture needs raw termios at 115200
- Step 13/14/25 and tables: use Debugger -> Add Hardware Breakpoint... (HE),
warn that F2 Toggle Breakpoint is a software breakpoint and never installs on
read-only flash
- new troubleshooting entry: r1 reverts to 0x2b (core running because the
breakpoint is not installed; registers widget is a per-stop snapshot)
- Step 13 rewritten: set/move breakpoints in the GUI, not the command port
- Steps 14/14b/25/25b: breakpoints via the GUI (command port only for the
RAM string write, which BN cannot do)
- Step 22/23: adapter corrected GDB RSP -> GDB MI
- cheat sheet, GUI-actions and OpenOCD tables: GUI-first, command port as fallback
- troubleshooting: real GDB MI causes (pre-existing breakpoint, gdb path, LLDB);
stops reported as Breakpoint not SingleStep
