  • Memory Protection Unit -R7

    各位专家,您好!

           我enable R7的MPU后,发生软件跑飞的情况,不知道怎样入手调试。麻烦各位专家指导下,谢谢!

    调试信息如下:


            /* Now we can safely enable the MPU in SCTLR register. */
            mrc             p15, #0, r0, c1, c0, #0
            orr             r0, r0, #MK_MPU_ENABLE
            dsb

  • Porting code From Cortex-A9 to Cortex-R7

    Hi,

     

    I have some bare metal code written for Arm cortex A9. I would like to port this code to cortex R7. Since both of them belong to ARMv7, How much effort will this take?

    I have never worked on cortex R processors. Will i be able to use the same assembly…

  • Fast Models (快速模型) 简介

    概况

    ARM系统的软件开发周期可因等待昂贵的开发硬件而延迟。要在当今的市场中保持竞争力,需要加快在完全验证的系统上开发全功能软件的速度。快速模型就是为这个目的而生。它提供高性能,丰富,准确的程序员视角(Programmer's View)模型库,支持最新的ARM IP。基于模型库构建的虚拟平台模型可使软件开发流程在硬件原型面世数月之前就启动,极大的缩短整个系统的开发时间。
