[U-Boot] Ask: How speed up read nand flash on lpc3250
CPU:LPC3250. Nand:K9F2G8U0A 256M the u-boot boot time now about 8s. the step to read linux kernel less 2M cost more or less 4s!! I want to make it faster~,but don't know how to. I try to change the memcpy function.but it's works not very well. so i want to via the maillist to find some help. thank you~~. --wizard

I don't see that string anywhere in the U-Boot tree -- what NAND driver are you using?

Make sure you are creating an on-chip bad block table (NAND_USE_FLASH_BBT). You'll still have to scan for bad blocks on first boot, but it should be much faster after that.
