TMS3206711 HPI

Terrence,

 

I am not sure of your exact question.  There are many ways to use the HPI - you can simply connect it to the EMIF of another processor.  You don't need any special functions - as long as you "wiggle the correct HPI bits".

 

If this doesn't help, maybe you could rephrase your question.

Sorry Mike for not being really clear, i'll try to rephrase it like that.

I have a board on which there is a TMS320c6711 on one of the PCI slots of my computer. What i'm trying to do is use the HPI to read or write a buffer in memory using the HPI. I tried to "wiggle" the right bits as you sais but i can't tell my host program (visual c++) to go read in memory. I initialized the HPIC register and HWOB but once you write in the HPIA register the adress in which you want to read, what are you suppose to toggle to tell the HPI to read in that adress and put the data in the HPID register?

What i didn't get maybe is that connection with the EMIF and the HPI. Can you be more precise on that?

I'm really new in that domain, this is why my questions can seem a little off, sorry. But your help is really appreciated.

Hi,

I was wondering if there was a way to communicate via the HPI without the emv6x or the dsk6x functions. Are there special adresses to watch ( EMIF, pci interfacing) before starting to initialize the HPIC register of the HPI? Could anyone help me on that?

Thanks very much!
