6457采用i2c加载,能烧进去但是加载不上,求教



6457采用i2c的方式加载,现在能烧进去,但是断电重启之后加载不上,我们检查测了时钟,在上电之后有时钟输出,感觉搬移成功了但是跳不到程序的入口地址。现在有两个地方想请教一下: 1.6457的boot parameter中software PLL的配置会影响PLL配置吗?Device address(LOW)的对应的DEVNUM[3:0]*0x80怎样理解,如果我想设LOW地址为0x80,DEVNUM的值应该设为多少?里面的*表示乘法的意思吗? Core frequency和bus frequency是什么关系?成比例吗? 2.DSP的PLL时钟配置跟boot有关系吗? 谢谢解答
