一、主核心的介绍 1.三个核心在FREERTOS系统中相互独立各负责各自的外设和程序其中M0和LP核心在一个总线上D0单独在一个总线上两个总线使用AXI4.0(??)通讯
CPU0(M0)-E907架构320MHz;
CPU1(LP)-E902架构160MHz;
CPU2(D0)-C906架构480MHz; 2.CPU0(M0)先启动然后再启动CPU2(C906),CPU1(e902)相关的代码在博流的SDK中位置如下/../BOUFFALO_SDK/bsp/board/bl808dk/board.c

其中按照顺序依次是
bflb_irq_save(); 关闭全局中断
GLB_Halt_CPU(GLB_CORE_ID_D0); 关闭D0核心
GLB_Halt_CPU(GLB_CORE_ID_LP); 关闭LP低功耗核心
bflb_flash_init(); 初始化FLASH
system_clock_init(); 初始化时钟
peripheral_clock_init(); 初始化外设时钟
bflb_irq_initialize(); 初始化中断
console_init(); 初始化串口
uhs_psram_init(); 初始化内置的64M UHS_PSRAM

CoreMark 1.0 : 2 / GCC10.2.0 -O3 / STACK 二、应用例程探究 看到好多网络上的例程和官方例程这里着重写几个有意思的 1、模拟GBA游戏机 例程来源于这里在这位的基础上增加了一个简单的查看FPS的小功能其实官方仓库都有这里做一个对比ESP32-S3 在分辨率是256*160跳帧为1的情况下是20帧我测试的BL808的C906在400Mhz,256*160分辨率下是33-37帧。而且后面的日志显示此时C906主频为400Mhz;
