(I expect it is, but it is good to start with the fundamentals.) If so, I would speculate your flash chip configuration isn't right. You need to know how your hardware is wired: * How many chips in parallel on the bus? * Bus width on each chip? * Bus width into the processor? Common configurations are things like one 8-bit wide chip running 8 bits into the processor, one 16-bit wide chip running 16 bits into the processor, two 16-bit wide chips in parallel running 32 bits into the processor. (Some flash chips can be configured to be either 8 or 16 bits wide depending on a strapping pin. For them, you need to figure out how the hardware has them configured.) Good luck, gvb _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
