PGA970: 用CCS调试的时候,'step into' 会乱跳。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: 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:
Target configuration:
Test connection success:
Build project success:
Download and start to debug OK:
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.
and also, DAC_SIN_NDS2_2 register was always not be able to read:
in addition, the DEMOD1_DATA and DEMON2_DATA were quite not stable:
Hope you can help us! appreciated!

您好,关于您的问题E2E已经给出答复:

关于这个问题,可能不能帮助到您这边太多,E2E给出了一个FAQ参考:

另外,您是否能否清除固件并查看是否可以从 DAC_SIN_NDSx 读取?

如果有其他问题,您直接在这里跟进就好。
