The console is the ST-LINK +Virtual COM Port at 115200 8N1. + +Persistent flash +---------------- + +OpenOCD adds the STM32N6 ROM header to ``nuttx.bin`` and programs the +on-board NOR flash with its ``stmqspi`` driver. Use an OpenOCD version +that provides ``target/stm32n6x.cfg``. + +Build and program the persistent boot image with: + +.. code:: console + + $ make flash + +This erases the affected flash sectors, programs and verifies the image, +and resets the board. ``OPENOCD`` and ``OPENOCD_TARGET`` can override the +OpenOCD executable and target script. The board's ``scripts/flash.cfg`` +configures the NOR pins, clocks and geometry for the native flash driver. + +For a CMake build configured in ``build``: + +.. code:: console + + $ cmake --build build --target flash + +Both targets build ``nuttx.bin`` before flashing. With CMake, ``OPENOCD`` +and ``OPENOCD_TARGET`` are cache variables set with ``-D`` at configuration. + +The boot ROM loads NuttX from flash and starts it without a debugger or +separate FSBL. +The header and padding occupy the first 1 KiB at ``0x34180000``; NuttX is +linked at ``0x34180400``. The ROM download buffer limits the binary to +511 KiB. The generated image is unauthenticated and requires a device +that permits unauthenticated boot. + +SRAM debugging +-------------- + +Build with ``make`` or ``cmake --build build``.

The next two commands initialize the stack pointer and entry point +from the vector table. Continue again after reaching ``nx_start`` to run +NSH. Reset before each reload; resetting after ``load`` boots the image +stored in flash instead. The SRAM image is lost on power-off. + +To inspect an already running image, attach with its matching ELF and omit +the reset, load and register-setting commands. + +NSH enables ``CONFIG_STM32N6_DEBUG`` to reopen debug access after ROM boot +and includes debug symbols.
