liuhaitao 459ad99373 Use EXTRAFLAGS instead of EXTRADEFINES to be used by make via command line So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor directive #warning in GCC.

configs/nsh	boards/arm/stm32/axoloti: Every BSP must provide boot board_late_initialize() AND board_app_initialize(). That is because you never now how the configuration will be set. CONFIG_LIB_BOARDCTL may be auto-selected by applications that need boardctl() support... requiring the existence of board_app_initialize().	2019-10-26 17:45:45 -06:00

memory and 256KiB of SRAM. The board features:

  - ADAU1961 24-bit 96 kHz stereo CODEC
  - 1/4" in/out jacks for analog audio signals
  - 3.5 mm jack for analog audio signals
  - 8 MiB of SDRAM (Alliance Memory AS4C4M16SA)
  - Serial MIDI in/out ports
  - SD Card slot
  - Two user LEDs and one (GPIO) push-button
  - USB OTG FS with Micro-AB connector (USB device mode operation)
  - USB OTG HS with Type-A connector (USB host mode operation)
  - Easy access to most IO pins
