OpenHarmony 3.0 operating system adapted to Loongson 1C300B chip

According to the latset news, OpenHarmony 3.0 was transplanted to the Zilong development board with MIPS ARCH and 1c300B chip transplantation within a week. However, at the moment, the multitasking switching, interrupts and systic have been ported.

Additionally, Tasks can be run and contexts switched normally. There are several key-press and LED code examples built into the code. The code is currently open source, allowing more developers to participate and improve together.

About Loongson 1C300B chip:

The 1C300 is a cost-effective single-chip system based on Loongson’s GS232 processor core. It has a built-in floating-point processing unit, supports multiple types of memory, supports large-capacity MLC flash memory chips, and can be used in industrial control, Internet of Things and other fields.

Currently, the latest OpenHarmony 3.0 supports various CPUs such as ARM, RISC-V and x86. But the current OpenHarmony 3.0 Lightweight System does not support MIPS architecture chips, only allow alone the Loongson development board with 1c300b chip.

OpenHarmony:

OpenHarmony is an open source project of HarmonyOS operating system incubated and operated by the OpenAtom Foundation. The goal is to build a framework and platform for a smart terminal device operating system and promote prosperity for a full-scenario, fully connected and fully smart era.

OpenHarmony 3.0:

OpenHarmony 3.0 will pave our way to the HarmonyOS 3.0 operating system version and it is  based on the OpenHarmony 2.2 Beta 2 and brings substantial improvements over the past versions.
