TMS320F28335: Error connecting to the target (Error -1015 @ 0x0)

Part Number: TMS320F28335

There is a legacy custom board having two F28335 MCUs with daisy-chain connection over single JTAG connection. The legacy team used BH USB 560v2 emulator which is not available now. So, we are trying with XDS200 emulator to connect with both the targets using 'js' scripts.

I was able to open the debug session using command 'session = dserv.openSession("Texas Instruments XDS2xx USB Debug Probe_0","C28xx"); '. But, when I try to connect to the target using 'session.target.connect();', I am getting 'Error connecting to the target (Error -1015 @ 0x0)'.

The support is needed on how to select between the two F28335 MCUs to connect and debug. What should be ccxml configuration file for 2 MCUs using single JTAG connection and how to manage it through scripting. 

Also, will there be a problem with JTAG HW design using XDS200 considering the legacy team were using BH 560v2 to flash the code.

Thanks,

Jai
