This is the first post in a weekly series tracking the development of Tock, a safe multi-tasking operating system for microcontrollers.

@TethysSvensson fixed the static_init! to only allocate as much static memory as needed.

@yuriks Upgraded Tock to Rust nightly version 2016-07-29, catching us up by over 7 months worth of nightly versions.

@KBaichoo implemented a driver for the SAM4L’s flash controller, which is a step towards replacing apps at runtime.

@phil-levis made significant progress on the NRF51822 port, implementing support for the real time counter and GPIO interrupts.

@utkarshapets contributed a UART driver for the NRF51822.
