IWR6843ISK: I have an earlier post about how my IWR6843ISK does not always connect to the RS232.

Part Number: IWR6843ISK

Tool/software:

I want to reload the original code the part came with.  What exactly is that code and where to find it?  Also, why do different boards consistently have different USB port numbers?  What did I accidentally do externally to cause a board to suddenly start working fine.  Does the POR (power on reset) maybe the issue?  When connecting a board to the PC, the PC knows what port the USB is connected to for that board, and it says everything is working fine.  But, the RS232 will not connect when using mmWave Studio.  Go figure!
