cuiziwei 25eb09c3bb nuttx/boards:add KEEP to (.init_array .init_array.) replace (.init_array .init_array.) with KEEP((.init_array .init_array.)). The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used. Signed-off-by: cuiziwei <cuiziwei@xiaomi.com>		2023-08-05 05:02:25 -07:00

======

The NuttX configuration for the Olimex STM32-P207 is assembled mainly
from the configurations stm32f4discovery and stm3240g-eval.

It was tested with the NuttX EABI "buildroot" Toolchain.

Debugging with OpenOCD via an Olimex ARM-USB-TINY-H works. Note that
CONFIG_DEBUG_SYMBOLS and CONFIG_STM32_DISABLE_IDLE_SLEEP_DURING_DEBUG
are enabled so that the JTAG connection is not disconnected by the idle
loop.

The following peripherals are enabled in this configuration.

 - LEDs:       show the system status

 - Buttons:    TAMPER-button, WKUP-button, J1-Joystick (consists of RIGHT-,
               UP-, LEFT-, DOWN-, and CENTER-button). Built in app
               'buttons' works.

 - ADC:        ADC1 samples the red trim potentiometer AN_TR
               Built in app 'adc' works.

 - USB-FS-OTG: Enabled but not really tested, since there is only a
               USB-A-connector (host) connected to the full speed STM32
               inputs.

 - USB-HS_OTG: The other connector (device) is connected to the high speed
               STM32 inputs (not enabled).

 - CAN:        Built in app 'can' works, but apart from that not really tested.

 - Ethernet:   Ping to other station on the network works.
