chao.an 1c8e12406e compile/opt: add config DEBUG_LINK_MAP Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld when linking NuttX ELF. That file can be useful for verifying and debugging magic section games, and for seeing which pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS.

README
======

The B-G431B-ESC Discovery kit board is based on the STM32G431CB microcontroller,
the L6387 driver and STL180N6F7 power MOSFETs.

UART/USART PINS
---------------

USART2 is accessible through J3 pads and ST LINK Virtual Console:
  USART2_TX - PB3
  USART2_RX - PB4

Configuration Sub-directories
-------------------------

  nsh:
  ---
    Configures the NuttShell (nsh) located at apps/examples/nsh.  The
    Configuration enables the serial interfaces on USART2.

  foc_f32 and foc_b16:
  ---------------------
    FOC examples based on hardware on board.
