现在在研究tci6614的 内存保护问题，本意是希望禁止dsp核访问arm内存，跑的一个简单的例子中mpu6如下配置 和 异常 打印
希望能得到帮助，如何建立6614的鲁棒性系统，急求解答，
ps：可以有偿回答，另招聘熟悉tci66系列的人员，可兼职/全职
联系方式：QQ2393082973
例程，是在msgcom通信例程基础上加了点MPU6的内容如下
if(0 == DNUM)
{
/* MPU0 PROG1 set protection of aif2 register address,CorePac1 & CorePac2 access only*/
//gpMPU_regs[0]->PROG_REGION[1].PROG_MPPA &= (0x03FFE400);
/* CorePac0~3 denied */
gpMPU_regs[6]->PROG_REGION[0].PROG_MPPA &= (0x03FDFE00);
gpMPU_regs[6]->PROG_REGION[1].PROG_MPPA &= (0x03FDFE00);
gpMPU_regs[6]->PROG_REGION[2].PROG_MPPA &= (0x03FDFE00);
gpMPU_regs[6]->PROG_REGION[3].PROG_MPPA &= (0x03FDFE00 |MP_NS|MP_EMU|MP_SR|MP_UR);
/* ARM denied*/
gpMPU_regs[6]->PROG_REGION[4].PROG_MPPA &= (0x00020000);
gpMPU_regs[6]->PROG_REGION[5].PROG_MPPA &= (0x00020000);
gpMPU_regs[6]->PROG_REGION[6].PROG_MPPA &= (0x00020000);
gpMPU_regs[6]->PROG_REGION[7].PROG_MPPA &= (0x00020000);
