    Hi,

    1. Currently we don't support daisy chained devices. ie. Only one connection is supported.

    2. To flash both cores of F28377d, create a session with that device, you should see both cores in the GUI.

    Hi Victor,

    Will (and when will) Uniflash support "Two TMS320F28335 DSPs on one board with one external JTAG connector.. which is connected to both DSPs thru a JTAG daisy-chain. " ?

    Thanks, Merril

    This is not on the road map so probably not anytime soon.

    Overall the tool is trying to be as simple as possible, focus on production requirements, and that might come with some limitations. This issue was foresaw and we decided to just go ahead without the daisy chain support.

    You can bring it up with Andy Waterson if you feel strongly about the need for this.

    In the mean time you will have to create 2 separate ccxml one for each device.
