U-Boot for Artis SBC-A3000
|
||||
---------------------------
|
||||
|
||||
Artis SBC-A3000 has one flash socket that the user uses Intel 28F128J3A (16MB)
|
||||
or 28F064J3A (8MB) chips.
|
||||
|
||||
In board's notation, bank 0 is the one at the address of 0xFF000000.
|
||||
bank 1 is the one at the address of 0xFF800000
|
||||
|
||||
On power-up the processor jumps to the address of 0xFFF00100, the last
|
||||
megabyte of the bank 0 of flash.
|
||||
|
||||
Thus, U-Boot is configured to reside in flash starting at the address of
|
||||
0xFFF00000. The environment space is located in flash separately from
|
||||
U-Boot, at the address of 0xFFFE0000.
|
||||
|
||||
There is a National ns83815 10/100M ethernet controller on-board.
