OpenHarmony 3.0 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.
