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-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 appart from that not really tested.

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