Hi All,

As a beginner's level task, I'm working on Spansion NOR flash memory
(S25FL127S) interfacing with STM32F072 (ARM Cortex M0 based SOC).
I've a custom board which has Spansion Flash memory connected to
STM32F072 over SPI bus.

I've a work-in-progress driver under: ~/RIOT/drivers/s25127s/s25127s.c
driver header: ~/RIOT/drivers/include/s25fl127s.h
and the driver test program: ~/RIOT/tests/driver_s25fl127s/main.c

However, As of now an attempt to build the test program failed. So
I tried to build driver test program for nvram-spi (since, this is the driver
that I'm referring to) instead and that too failed.

[amit at discworld driver_nvram_spi]$ make
There are unsatisfied feature requirements: periph_gpio periph_spi


Building application "driver_nvram_spi" for "native" with MCU "native".

Seems that, I may have to export some environment variables or update some
Makefiles for building my driver test application. I'm wondering, if there is
any document on writing and testing drivers for RIOT ?

My setup environment:
Host: Linux, x86_64
