sm320f28335 with xds100v2

Other Parts Discussed in Thread: TMS320F28335

Hello,

I have an sys/bios application running on a SM320F28335 that I am programming and debugging with an XDS100v2. I am unable to program the board because the state of the GPIO's causes the board to reset (hardware reset).

The datasheet for the processor says that GPIO's 12-87 have a weak internal pullup. But when I scope some of these lines while I am programming that is not what I am seeing. Does the XDS100v2 do anything with the state of GPIO's while connecting or programming?

My next question is has anyone used any of the more advanced programmers with am SM320F28335 or TMS320F28335? Specifically the XDS510 or XDS560. Do either of these programmers do anything different than the XDS100 in terms of control over the GPIOs of the processor it is programming?

Thanks,

Bruce

    Hi Bruce,

    According to my perception(I'm using both), the only difference is the speed! I would prefer using XDS510/560 for production purpose. Check this out for more clarifications:
