Intrinsyc will not provide the physical address locations for anything on their board, which is ridiculous. I have determined, based on the DCR registers, that the following memory addresses are used:
SDRAM is located at 0x00000000 with 32MB size. (NOR??) located at 0xFFE000000 with size 2MB (NAND??) located at 0x60000000 with size 1MB Based on Intrinsyc's code, they appear to use 0x60000000 as the base address for the NAND flash, but the register reads a 1MB size instead of 32MB. I suspect the other location is the NOR flash. So now I'm trying to use address 0x04000000 with CS2\. How do I map the phyiscal address? /* EBC0 Registers */ EBC0_B0CR : 0xffe3a000 EBC0_B1CR : 0x60018000 EBC0_B2CR : 0x00000000 EBC0_B3CR : 0x00000000 EBC0_B4CR : 0x00000000 EBC0_B0AP : 0x04002480 EBC0_B1AP : 0x04005480 EBC0_B2AP : 0x00000000 EBC0_B3AP : 0x00000000 EBC0_B4AP : 0x00000000 EBC0_BEAR : 0x00000000 EBC0_BESR0 : 0x00000000 EBC0_BESR1 : 0x00000000 EBC0_CFG : 0x80400000 /* SDRAM0 Registers */ SDRAM0_CFG : 0x80a00000 SDRAM0_STATUS: 0x80000000 SDRAM0_RTR : 0x07e80000 SDRAM0_PMIT : 0x07c00000 SDRAM0_B0CR : 0x00062001 SDRAM0_B1CR : 0x00000000 SDRAM0_TR : 0x010bc01b Setting up EBC registers...
