Gregory Nutt 2eb4fe5ffb Make sure sections are aligned to 32-bits in all LD linker scripts. This fixes and issues noted specifically for the SAMD21 by Bernd Walter, but should be applicable to all other LD scripts as well. Squashed commit of the following: configs/: Add . = ALIGN(4); before every .data section configs/: Add . = ALIGN(4); before every ARM.extab section configs/: Add . = ALIGN(4); before every definition of __exidx_start configs/: Add . = ALIGN(4); before every .init_section. configs/: Convert TABs to spaces in all ld linker scripts. This just makes things easier to modify with scripts because the files are more consistent.		2019-05-30 16:51:38 -06:00

======

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.
