Detailed Description

Support for Eistec Mulle IoT boards.


The Mulle is a miniature wireless Embedded Internet System suitable for wireless sensors connected to the Internet of Things, and designed for rapid prototyping. It can be bought directly from Eistec AB.

Use BOARD=mulle for building RIOT for this platform.


https://github.com/eistec/mulle/wiki/Datasheets contains a list of relevant documentation for the components.

MCU MK60DN512VLL10 – Cortex-M4
RAM 64kB
Flash 512kB
radio chipset AT86RF212B, sub-GHz IEEE802.15.4 transceiver, similar to the AT86RF233
external flash memory Micron M25P16 16 Mbits external NOR flash, used for storing configuration, measurements and other slow changing non-volatile data
external FRAM memory Cypress/Ramtron FM25L04B 4 Kbits external F-RAM, used for storing counters and other rapidly changing non-volatile data
accelerometer ST micro LIS3DH MEMS accelerometer,

See ARM Family, and Eistec wiki - Installing-toolchain (GCC)

Working: gcc-arm-embedded Clang 3.4 - Clang 4.0 - Install procedure not documented but pretty straightforward, Makefiles and build system is fully functional with Clang.
