ppcboot for a CU824 board
|
|
---------------------------
|
|
|
|
CU824 has two banks of flash 8MB each. In board's notation, bank 0 is
|
|
the one at the address of 0xFF800000 and bank 1 is the one at the
|
|
address of 0xFF000000. 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 not embedded in the U-Boot code
|
|
and is located in flash separately from U-Boot, at the address of
|
|
0xFF008000.
