Tonga 2 Linux Change History 2010-05-12 New NAND driver fixes several bugs and increases performance. NOTES: The OOB layout has changed, you cannot use filesystems flashed with the old U-Boot release. This bootloader is not able to replace itself, you need to use J-Link Commander to replace it. Do not worry about bad error messages if you start your updated U-Boot - they will go away once you have installed a kernel image. If you do have the environment from an old U-Boot in flash you might need to change the boot command to this: setenv bootcmd nand read 0x40600000 0x80000 0x200000 \; bootm 0x40600000 USB support is enabled as well as HID and storage drivers in kernel.
