I'm not sure, that i've found right forum, but i need your help, friends =)I have a problem with XBus on TMS320C6203B. I can't do anything with it!What i have:I can write my program into C6203B and usually it works correctly ;) But, when i try to use XBus - it doesn't happen.What i need: i need to get high level on all of the XD pins [31-0] and after that, low level on them - and no more. It will be enough. In which mode (synchronous\asynchronous is not important)But, to be honest, i don't know how to run this freaking bus!I read all datasheets (including spru579a "XBus" and spru577a "DMA"), but despite this can't solve this simple problem.It would be great, if anybody could help me.
P.S Actually if you could give me C or asm little code example, it would be better solution, than just good advice... :)
I've solved the problem.In my case, there is no need to program anything =)Just pull-up and pull-down necessary pins (XCS, XCNTL, XW\R and some others) to get asynchronous host port mode and to run XBus external.Details can be found here: spru579a "XBus" (since page 42 and later)
