II. NAND partition table
|
|
|
|
All the board support boot from NAND flash will use the following NAND
|
|
partition table
|
|
|
|
0x00000000 - 0x0003FFFF bootstrap (256 KiB)
|
|
0x00040000 - 0x000BFFFF u-boot (512 KiB)
|
|
0x000C0000 - 0x000FFFFF env (256 KiB)
|
|
0x00100000 - 0x0013FFFF env_redundant (256 KiB)
|
|
0x00140000 - 0x0017FFFF spare (256 KiB)
|
|
0x00180000 - 0x001FFFFF dtb (512 KiB)
|
|
0x00200000 - 0x007FFFFF kernel (6 MiB)
|
|
0x00800000 - 0xxxxxxxxx rootfs (All left)
|
|
|
|
III. Watchdog support
|
|
|
|
For security reasons, the at91 watchdog is running at boot time and,
|
|
if deactivated, cannot be used anymore.
|
|
If you want to use the watchdog, you will need to keep it running in
|
|
your code (make sure not to disable it in AT91Bootstrap for instance).
|
|
|
|
In the U-Boot configuration, the AT91 watchdog support is enabled using
|
|
the CONFIG_AT91SAM9_WATCHDOG and CONFIG_HW_WATCHDOG options.
