IWR6843ISK: IWR6843ISK dss系统串口发送数据的疑惑

Part Number: IWR6843ISK
Other Parts Discussed in Thread: MMWAVEICBOOST, IWR6843

HI, 您好!

我最近在学习mmwave_sdk_03_05_00_04 里面的串口用例,在学习mmwave_sdk_03_05_00_04\packages\ti\drivers\uart\test\xwr68xx\main_dss.c代码时,发现dsp并未初始化对应的Gpio口,但是对过pc的串口助手收到 dsp核发过来的数据。  (前提:需要在MMWAVEICBOOST设置对应的拨码开关值 )

对此,我想知道在dss系统时,dsp不需要初始化Gpio吗?  请解答。
