6678 时钟问题,TI官方给的测试文件结果为PLL输入 时钟50MHz,但是后面配置PLL时是按100MHz?



(1)6678  时钟问题,TI官方给的测试文件结果为PLL输入 时钟50MHz,但是后面配置PLL时是按100MHz?

请帮忙解释下这个问题。

(2)我们自制的板子测试出来时钟时66.7MHz,请问这个说明了什么 原因?

  • 具体是哪个时钟? 只要输入时钟PLL倍频分频后 满足所需lane或者系统主频要求即可


  • (1)K1_STK_v1.1.zi  文件中,连接开发板后测试信息:JTAG ID= 0x1009e02f. This is C6678/TCI6608 device, version variant = 1.

    DEVSTAT= 0x00010081. little endian, No boot or EMIF16(NOR FLASH) or UART boot, PLL configuration implies the input clock for core is 50MHz.

    。这块的50MHz,和后面进行Initialize DSP main clock 的100Mhz的时钟有什么关系?

    (2)我们自己焊接的板子测试时钟为66.7MHz,请问者说明一个什么状态?
