I am using a TI micro for the first time and have been struggling to get comms with it via a XDS100V3 JTAG emulator.
The micro in question is the TMS320F28379D
I am using an SMT to through hole adapter board just for prototyping but want to understand some fundamentals with this micro.
Firstly what is the minimum I need connected in order to get JTAG comms. I assume I need to supply the VDD3VFL and VDD.
Do i need to supply the VDDIO at all?
I have also installed a pull up on the XRS pin to 3.3V
I have made the JTAG connection as shown on the attachment however get an error that the scan paths cannot circulate bits.
