Hi, 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.
Here are my settings : DCM : DMA_WRAP=101, SINC=1, DINC=1, S/D=00 STS: 2016 SS_MAX: 2016 BUF_INV: 2048 DTS: 2016 Transfer buffer size is 2048 bytes BD flags : V=1, W=1, I=1, L=1, BD Len = 1024 Any help will be appreciated. Thanks -Arun
