Motorola MPC85xxCDS boards
|
||||
--------------------------
|
||||
|
||||
The CDS family of boards consists of a PCI backplane called the
|
||||
"Arcadia", a PCI-form-factor carrier card that plugs into a PCI slot,
|
||||
and a CPU daughter card that bolts onto the daughter card.
|
||||
|
||||
Much of the content of the README.mpc85xxads for the 85xx ADS boards
|
||||
applies to the 85xx CDS boards as well. In particular the toolchain,
|
||||
the switch nomenclature, and the basis for the memory map. There are
|
||||
some differences, though.
|
||||
|
||||
|
||||
Building U-Boot

chip. You need to use binutils-2.14.tar.bz2 (or newer) from

|

The 85xx CDS code base is known to compile using:

Memory Map
|
||||
----------
|
||||
|
||||
The memory map for u-boot and linux has been extended w.r.t. the ADS
|
||||
platform to allow for utilization of all 85xx CDS devices. The memory
|
||||
map is setup for linux to operate properly. The linux source when
|
||||
configured for MPC85xx CDS has been updated to reflect the new memory
|
||||
map.
|
||||
|
||||
The mapping is:

|
||||
|
||||
|
||||
Using Flash
|
||||
-----------
|
||||
|
||||
The CDS board has two flash banks, each 8MB in size (2^23 = 0x00800000).
|
||||
There is a switch which allows the boot-bank to be selected. The switch
|
||||
settings for updating flash are given below.
|
||||
|
||||
The u-boot commands for copying the boot-bank into the secondary bank are
|
||||
as follows:
|
||||
|
||||
erase ff780000 ff7fffff
|
||||
cp.b fff80000 ff780000 80000
|
||||
|
||||
|
||||
U-boot/kermit commands for downloading an image, then copying
|
||||
it into the secondary bank:
|
||||
|
||||
loadb
|
||||
[Drop to kermit:
|
||||
^\c
|
||||
send <u-boot-bin-image>
|
||||
c
|
||||
]
|
||||
|
||||
erase ff780000 ff7fffff
|
||||
cp.b $loadaddr ff780000 80000
|
||||
|
||||
|
||||
U-boot commands for downloading an image via tftp and flashing
|
||||
it into the second bank:
|
||||
|
||||
tftp 10000 <u-boot.bin.image>
|
||||
erase ff780000 ff7fffff
|
||||
cp.b 10000 ff780000 80000
|
||||
|
||||
|
||||
After copying the image into the second bank of flash, be sure to toggle
|
||||
SW2[2] on the carrier card before resetting the board in order to set the
|
||||
secondary bank as the boot-bank.
|
||||
|
||||
|
||||
Carrier Board Switches
|
||||
----------------------
|
||||
|
||||
As a reminder, you should read the README.mpc85xxads too.
|
||||
|
||||
Most switches on the carrier board should not be changed. The only
|
||||
user-settable switches on the carrier board are used to configure
|
||||
the flash banks and determining the PCI slot.
|
||||
|
||||
The first two bits of SW2 control how flash is used on the board:
|
||||
|
||||
12345678
|
||||
--------
|
||||
SW2=00XXXXXX FLASH: Boot bank 1, bank 2 available.
|
||||
01XXXXXX FLASH: Boot bank 2, bank 1 available (swapped).
|
||||
10XXXXXX FLASH: Boot promjet, bank 1 available
|
||||
11XXXXXX FLASH: Boot promjet, bank 2 available
|
||||
|
||||
The boot bank is always mapped to FF80_0000 and listed first by
|
||||
the "flinfo" command. The secondary bank is always FF00_0000.
|
||||
|
||||
When using PCI, linux needs to know to which slot the CDS carrier is
|
||||
connected.. By convention, the user-specific bits of SW2 are used to
|
||||
convey this information:
|
||||
|
||||
12345678
|
||||
--------
|
||||
SW2=xxxxxx00 PCI SLOT INFORM: The CDS carrier is in slot0 of the Arcadia
|
||||
xxxxxx01 PCI SLOT INFORM: The CDS carrier is in slot1 of the Arcadia
|
||||
xxxxxx10 PCI SLOT INFORM: The CDS carrier is in slot2 of the Arcadia
|
||||
xxxxxx11 PCI SLOT INFORM: The CDS carrier is in slot3 of the Arcadia
|
||||
|
||||
These are cleverly, er, clearly silkscreened as Slot 1 through 4,
|
||||
respectively, on the Arcadia near the support posts.
|
||||
|
||||
|
||||
The default setting of all switches on the carrier board is:
|
||||
|
||||
12345678
|
||||
--------
|
||||
SW1=01101100
|
||||
SW2=0x1111yy x=Flash bank, yy=PCI slot
|
||||
SW3=11101111
|
||||
SW4=10001000
|
||||
|
||||
|
||||
CPU Card Switches
|
||||
-----------------
|
||||
|
||||
Most switches on the CPU Card should not be changed. However, the
|
||||
frequency can be changed by setting SW3:
|
||||
|
||||
12345678
|
||||
--------
|
||||
SW3=XX00XXXX == CORE:CCB 2:1
|
||||
XX01XXXX == CORE:CCB 5:2
|
||||
XX10XXXX == CORE:CCB 3:1
|
||||
XX11XXXX == CORE:CCB 7:2
|
||||
XXXX1000 == CCB:SYSCLK 8:1
|
||||
XXXX1010 == CCB:SYSCLK 10:1
|
||||
|
||||
A safe default setting for all switches on the CPU board is:
|
||||
|
||||
12345678
|
||||
--------
|
||||
SW1=10001111
|
||||
SW2=01000111
|
||||
SW3=00001000
|
||||
SW4=11111110
|
||||
|
||||
|
||||
eDINK Info
|
||||
----------
|
||||
|
||||
One bank of flash may contain an eDINK image.
|
||||
|
||||

||||
