It worked on a smaller 64M NAND. Currently you need to define the page-size of the NAND used for booting (512 bytes vs. 2k). The 2k 4xx NAND booting support is was done about 1/2 a year ago. So perhaps you tested this when this 2k support was not available yet. > So we put our FPGA and u-boot in a small NOR. The kernel, rootfs and > other files are on the NAND. Yes, I would recommend to do it this way if possible. A small NOR for U-Boot and environment and everything else in NAND. This makes things much easier. But I understand that this is sometimes a problem with space (2 FLASH chips) and costs.
