<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am having some problem with the PCI burst using the
MPC8248 IDMA feature. I can get a continuous burst of 2k when transferring data
from the system memory to the PCI direction but in the other direction (i.e.
PCI to system memory) the PCI burst is fragmented with 32 bytes of fragment. I
have verified that the Prefetch bit is set in the POCMR register.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here are my settings :<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoPlainText>DCM : DMA_WRAP=101, SINC=1, DINC=1, S/D=00<o:p></o:p></p>
<p class=MsoPlainText>STS: 2016<o:p></o:p></p>
<p class=MsoPlainText>SS_MAX: 2016<o:p></o:p></p>
<p class=MsoPlainText>BUF_INV: 2048<o:p></o:p></p>
<p class=MsoPlainText>DTS: 2016<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Transfer buffer size is 2048 bytes<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>BD flags : V=1, W=1, I=1, L=1, BD Len = 1024<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Any help will be appreciated.<o:p></o:p></p>
