NAND partition table
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
All the board support boot from NAND flash will use the following NAND
|
||
|
|
partition table::
|
||
|
|
|
||
|
|
0x00000000 - 0x0003FFFF bootstrap (256 KiB)

|
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_WDT and CONFIG_WDT_AT91 options.
|
