Intel® Quark™ Microcontroller Software Interface (QMSI) is a Hardware Abstraction Layer (HAL) for Intel® Quark™ Microcontroller products. It currently support the following SoCs:

• Intel® Quark™ D2000 Microcontroller
• Intel® Quark™ SE Microcontroller

Information and support regarding Intel® Quark™ MCUs can be found in the following website:

http://www.intel.com/quark/mcu

This release has been validated with the following hardware:

• Intel® Quark™ Microcontroller D2000 Series.
• Intel® Quark™ Microcontroller D2000 Development Platform.

• The i586-intel-elfiamcu toolchain is required to build the source code.
• OpenOCD is required to flash applications and ROM files onto the SoC.
• GDB is optional, it is used as a supplement to OpenOCD for debugging.
• Intel® System Studio for Microcontrollers is optional.

The build system is based on the make tool.

Debug and release builds are supported setting the BUILD variable.

To build in debug mode:

make BUILD=debug

To build in release mode:

make BUILD=release

The top level Makefile contains two targets: rom and libqmsi. The output directory is build.

The ROM must be flashed on the OTP ROM flash region. To build the rom target, run:

make rom

Libqmsi is a library archive of all the QMSI drivers for the SoC.

To build the libqmsi target, run the following command from the top level directory:

make libqmsi

To build any of the provided example apps run make inside the corresponding directory or use the –C make option from the top level directory.

E.g. to build the hello_world example app (by default it will be built in debug mode):

make –C examples/hello_world
