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-H405 is based on the configuration
Olimex STM32-P207.

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.

Make sure that '# CONFIG_NSH_CONDEV is not set' is in the .config file - it defaults
to '/dev/console' which makes problems with the shell over USB.

The following peripherals are enabled in this configuration.
 - LED:        Shows the system status

 - Button:     Built in app 'buttons' works.

 - ADC:        ADC1 samples ADC_IN1. Built in app 'adc' works.

 - USB-FS-OTG: The console is running on the virtual serial port. Note that you
               have to press enter three times until NSH appears.

 - CAN:        Built in app 'can' is enabled but not tested, since no CAN transceiver
               is on board.
