And the EBC0_BxCR & EBC0BxAP registers for the CS where the NAND is connected? How are they configured?EBC0_B1CR d001c000 EBC0_B1AP 18003c0 Which matches the defines in include/configs/warp.h: #define CFG_EBC_PB1AP 0x018003c0 #define CFG_EBC_PB1CR (CFG_NAND_ADDR | 0x1c000) It also matches the defines in sequoia.h except that we are on CS1 and the sequoia is on CS3.
Right. One thing I noticed though is, that you map the NAND to 0xd0000000, which is reserved for PCI in the 440EP address space. I suggest you map it to 0x90000000 as done on Bamboo. Please give it a try and let me know if this changes the 32bit access behavior.
