Does its NAND controller resemble any of the drivers under drivers/mtd/nand? If so, look at what other boards using that controller are doing. If not, you'll need to write a controller driver. What that driver looks like depends on how the hardware works -- do you have a simple interface to read/write bytes or words, and raise/lower some signals? Maybe with an ECC accelerator? Or does the hardware isolate you more from the hardware details, such that you program it to do high level operations such as read page, erase block, etc? -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
