MCU25 Configuration Details
|
||||
|
||||
Memory Bank 0 -- Flash chip
|
||||
---------------------------
|
||||
|
||||
0xfff00000 - 0xffffffff
|
||||
|
||||
The flash chip is really only 512Kbytes, but the high address bit of
|
||||
the 1Meg region is ignored, so the flash is replicated through the
|
||||
region. Thus, this is consistent with a flash base address 0xfff80000.
|
||||
|
||||
The placement at the end is to be consistent with reset behavior,
|
||||
where the processor itself initially uses this bus to load the branch
|
||||
vector and start running.
|
||||
|
||||
On-Chip Memory
|
||||
--------------
|
||||
|
||||
0xf4000000 - 0xf4000fff
|
||||
|
||||
The 405GPr includes a 4K on-chip memory that can be placed however
|
||||
software chooses. I choose to place the memory at this address, to
|
||||
keep it out of the cachable areas.
|
||||
|
||||
|
||||
Internal Peripherals
|
||||
--------------------
|
||||
|
||||
0xef600300 - 0xef6008ff
|
||||
|
||||
These are scattered various peripherals internal to the PPC405GPr
|
||||
chip.
|
||||
|
||||
Chip-Select 2: Flash Memory
|
||||
---------------------------
|
||||
|
||||
0x70000000
|
||||
|
||||
Chip-Select 3: CAN Interface
|
||||
----------------------------
|
||||
0x7800000
|
||||
|
||||
|
||||
Chip-Select 4: IMC-bus standard
|
||||
-------------------------------
|
||||
|
||||
Our IO-Bus (slow version)
|
||||
|
||||
|
||||
Chip-Select 5: IMC-bus fast (inactive)
|
||||
--------------------------------------
|
||||
|
||||
Our IO-Bus (fast, but not yet use)
|
||||
|
||||
|
||||
Memory Bank 1 -- SDRAM
|
||||
-------------------------------------
|
||||
|
||||
0x00000000 - 0x2ffffff # Default 64 MB
