📄️ Configure Uboot and Kernel Option Parameters
In system software development, it is often necessary to configure feature options for Uboot and the kernel. This chapter introduces several commonly used configuration methods for user reference.
📄️ UART Driver Debugging Guide
The S100 chip has a total of four UART interfaces, namely UART0 to UART3. Among them, UART0 is used as the debug console. By default, DMA is disabled for UART0, and its baud rate (either 115200 or 921600) is determined by the Bootstrip pin configuration.

Preface
📄️ GPIO Usage
The S100 Acore chip contains three sys GPIO devices: peri, cam, and video. Each device supports up to 32 GPIO pins, and every GPIO pin supports interrupts.

📄️ Introduction to the IPC Module
The IPC (Inter-Processor Communication) module enables communication between multiple cores, supporting both homogeneous and heterogeneous core communication. On the software side, it manages shared memory based on a buffer-ring mechanism; on the hardware side, it implements inter-core interrupts using MailBox. IPCF features multiple channels, supports large data transfers, and is adaptable across various platforms. RPMSG is built upon an open-source protocol framework and supports inter-core communication between Acore and VDSP.
