PGA970: 用CCS调试的时候,'step into' 会乱跳, DAC_SIN_NDS2_2寄存器总是不能被读取, 并且DEMONx_DATA的值也是非常不稳定。

Part Number: PGA970

我们是用PGA970自己做板开发,

CCS V12.1.0.00007

Compiler version 编译器版本: TI v5.2.6

使用的硬件调试工具的具体型号是 XDS2xx,

烧录时没有报错,

指针乱跳的具体现象截图说明如下:

But when I jumped into APP_Reset_Init() function and click 'Step into' button, it would go to line#180, then jump to line#187, which was weird.
但是 当我调试进入APP_Reset_Init()函数,并点击'Step into'按键,指针会跳转到180行,再按'Step into'按键,会跳转到187行,并没有按照顺序执行,很奇怪:


and also, DAC_SIN_NDS2_2 register was always not be able to read:

并且,DAC_SIN_NDS2_2寄存器总是不能被读取:


in addition, the DEMOD1_DATA and DEMON2_DATA were quite not stable:

此外,DEMOD1_DATA 和DEMON2_DATA寄存器的值一直在跳变,不稳定:
