在Linux系统中配置双核处理器通常涉及到确保系统能够识别和使用两个CPU核心。以下是一些基础概念和相关步骤: 基础概念 多核处理器:现代CPU通常有多个核心,每个核心可以独立执行任务,从而提高处理速度和效率。 SMP(对称多处理):Linux系统支持SMP,允许多个CPU核心同时工作。
我继续对ipc_rpmsg_linux_echo的工程做修改。基于上面所做的修改,我对该ipc_rpmsg_linux_echo例子里所有工程的linker.cmd和example.syscfg文件做修改。 被修改的工程: ipc_rpmsg_echo_linux_am64x-evm_m4fss0-0_freertos_ti-arm-clang ipc_rpmsg_echo_linux_am64x-evm_r5fss0-0_freertos_...
