Hello, I'm a newbie using U-boot and met several problems with a customized board based on MPC8315E-RDB board. On the new board, I have changed the Ethernet PHY to TI's DP83848 and NAND FLASH to 64Mbit (from old 32Mbit).
During U-boot form NOR FLASH , I met two problems :
1, if NAND flash support is enabled, U-boot just print out "NAND : " without size info and then print out text like "machine check ...,", then print out "resetting board ..." So the board keep resetting again and again. Does this have anything to do with NAND FLASH size change or NAND PART types?
Make sure that the physical address you're trying to map NAND at is covered by a LAW that points to eLBC, and that the LAW, eLBC, and TLB physical addresses match.
