This report presents the work done on modifying the lightweight Mutek operating system to add support for two complex Arm-based SoC architectures. Both of these platform use nearly the same ARMv4 core CPU model but have a different memory map and integrate different system peripherals such as interrupt controller, timer and serial interfaces. An initial support for MMU operations using an identity mapping has also been added to the hardware abstraction layer. This support was compulsory to access hardware information needed to activate the data cache.
