IWR6843AOP: SOP and JTAG Errors

Part Number: IWR6843AOP

Tool/software:

Trying to program via JTAG a custom board designed around the 6843AOP. Can it be verified what the SOP values should be for JTAG? Seems like there is some confusion even on the forums. These are the errors we are seeing:

Error -1170 @ 0x0) Unable to access the DAP.

and

Error connecting to the target:

(Error -6305) PRSC module failed to write to a router register.

(Emulation package 12.7.0.00130)
