TMS320F28335: uniflash program dual core

TMS320F28335: Using Uniflash to program multiple devices on one JTAG connection

Part Number: TMS320F28335
Other Parts Discussed in Thread: UNIFLASH

I want to use Uniflash and a Black Hawk XDS 200 to program a board with four F28335 (three with the same program, one different). I see from the linked thread that I cannot use one UniFlash configuration to program all four DSPs. I wonder if anyone can provide example configuration files to direct Uniflash to each DSP in turn, so I can select each DSP and program it. Ideally the example will be a .ccxml target configuration from CCS with multiple DSPs and one or more single DSP ccxml files to program each DSP in turn.

    Nigel,

    I apologize for the very late reply here.  This thread was brought to my attention a few minutes ago.  I am not sure if you have figured this out yet or not.

    The way that I would do this is that I would create a ccxml file in CCS that has all 4 F28335 devices in it.  I would then create variations of the .ccxml file where all but 1 of the devices are bypassed.  You could then script UniFlash to program each device individually using the different ccxml files.

    In the attached zip I have created some reference .ccxml files.  1 has all 4 F28335s in it, the others have all but 1 of the F28335s bypassed.  I don't have a setup here with 4 F28335s in it to try this on.
