Hi, Thanks for your reply, Bin! I checked system.mhs and "C_BRIDGE_IDSEL_ADDR_BIT" was set to 16, but the code that was in pci_init( ) was the code for as if "C_BRIDGE_IDSEL_ADDR_BIT" was set to 24. After replacing the code in pci_init( ), the PCI now initializes. However, after the ML310 initi

Hi Misbah, I am running the algorithm on OMAP processor (arm-core) and i did tried the same on iMX processor which takes 1.7 times more than OMAP. Ok, thats a 10,000ft benchmark. The observation being that it fails your requirement. How does that time compare to the operations required, and t

Hi all, do someone know how to speedup the gianfar on mpc8313?
