I am a beginner of DSP. Now I use EVM2407 and DSK6713 to do the paralel
communication. I use EMIF of 2x and HPI of 6x to do such work. As in
the reference spra512, the HPI of 6x is mapped into the host memory
space. The address pin[3:2] and address pin [1] of 2x's EMIF are
connected to HCNTL[1:0] and HHWIL respectively. I want to transfer a
data from 2x to 6x through HPI. But from the running result, the data
can not transferred to the 6x. I think the reason is that the HPI
registers were not mapped into the host memory space, so them were not
accessed by host. I can not understand the mapping principle of the HPI
registers. Who can give me the detailed explanation? Thanks a lot!
HELP!!!How are HPI registers mapped into the host memory space?
