Freescale MPC832XEMDS Board
-----------------------------------------
1. Board Switches and Jumpers
1.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS board
For some reason, the HW designers describe the switch settings
in terms of 0 and 1, and then map that to physical switches where
the label "On" refers to logic 0 and "Off" is logic 1.
Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
bits may contribute to signals that are numbered based at 0,
and some of those signals may be high-bit-number-0 too. Heed
well the names and labels and do not get confused.
"Off" == 1
"On" == 0
SW3 is switch 18 as silk-screened onto the board.
SW4[8] is the bit labled 8 on Switch 4.
SW5[1:6] refers to bits labeled 1 through 6 in order on switch 5.
SW6[7:1] refers to bits labeled 7 through 1 in order on switch 6.
SW7[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On"
and bits labeled 8 is set as "Off".
1.1 For the MPC832XEMDS PROTO Board
First, make sure the board default setting is consistent with the document

3. Definitions
3.1 Explanation of NEW definitions in:
include/configs/MPC832XEPB.h
CONFIG_MPC83XX MPC83XX family for MPC8349, MPC8360 and MPC832X
CONFIG_MPC832X MPC832X specific
CONFIG_MPC832XEMDS MPC832XEMDS board specific
4. Compilation
Assuming you're using BASH shell:
export CROSS_COMPILE=your-cross-compile-prefix
cd u-boot
make distclean
make MPC832XEMDS_config
make
MPC832X support PCI 33MHz and PCI 66MHz, to make u-boot support PCI:
1)Make sure the DIP SW support PCI mode as described in Section 1.1.
2)To Make U-Boot image support PCI 33MHz, use
Make MPC832XEMDS_HOST_33_config
3)To Make U-Boot image support PCI 66MHz, use
Make MPC832XEMDS_HOST_66M_config
5. Downloading and Flashing Images
5.0 Download over network:
tftp 10000 u-boot.bin
5.1 Reflash U-boot Image using U-boot
tftp 20000 u-boot.bin
protect off fe000000 fe0fffff
erase fe000000 fe0fffff
cp.b 20000 fe000000 xxxx
You have to supply the correct byte count with 'xxxx' from the TFTP result log.
Maybe 3ffff will work too, that corresponds to the erased sectors.
6. Notes
1) The console baudrate for MPC832XEMDS is 115200bps.

Freescale MPC8349E-mITX and MPC8349E-mITX-GP Boards
---------------------------------------------------
1. Board Description
The MPC8349E-mITX and MPC8349E-mITX-GP are reference boards featuring
the Freescale MPC8349E processor in a Mini-ITX form factor.
The MPC8349E-mITX-GP is an MPC8349E-mITX with the following differences:
A) One 8MB on-board flash EEPROM chip, instead of two.
B) No SATA controller
C) No Compact Flash slot
D) No Mini-PCI slot
E) No Vitesse 7385 5-port Ethernet switch
F) No 4-port USB Type-A interface
2. Board Switches and Jumpers
2.0 Descriptions for all of the board jumpers can be found in the User
Guide. Of particular interest to U-Boot developers is jumper J22:
Pos. Name Default Description
-----------------------------------------------------------------------
A LGPL0 ON (0) HRCW source, bit 0
B LGPL1 ON (0) HRCW source, bit 1
C LGPL3 ON (0) HRCW source, bit 2
D LGPL5 OFF (1) PCI_SYNC_OUT frequency
E BOOT1 ON (0) Flash EEPROM boot device
F PCI_M66EN ON (0) PCI 66MHz enable
G I2C-WP ON (0) I2C EEPROM write protection
H F_WP OFF (1) Flash EEPROM write protection
Jumper J22.E is only for the ITX, and it decides the configuration
of the flash chips. If J22.E is ON (i.e. jumpered), then flash chip
U4 is located at address FE000000 and flash chip U7 is at FE800000.
If J22.E is OFF, then U7 is at FE000000 and U4 is at FE800000.
For U-Boot development, J22.E can be used to switch back-and-forth
between two U-Boot images.
3. Memory Map
3.1. The memory map should look pretty much like this:
0x0000_0000 - 0x0FFF_FFFF DDR SDRAM (256 MB)
0x8000_0000 - 0x9FFF_FFFF PCI1 memory space (512 MB)
0xA000_0000 - 0xBFFF_FFFF PCI2 memory space (512 MB)
0xE000_0000 - 0xEFFF_FFFF IMMR (1 MB)
0xE200_0000 - 0xE2FF_FFFF PCI1 I/O space (16 MB)
0xE300_0000 - 0xE3FF_FFFF PCI2 I/O space (16 MB)
0xF000_0000 - 0xF000_FFFF Compact Flash (ITX only)
0xF001_0000 - 0xF001_FFFF Local bus expansion slot
0xF800_0000 - 0xF801_FFFF Vitesse 7385 Parallel Interface (ITX only)
0xFE00_0000 - 0xFE7F_FFFF First 8MB bank of Flash memory
0xFE80_0000 - 0xFEFF_FFFF Second 8MB bank of Flash memory (ITX only)
3.2 Flash EEPROM layout.
On the ITX, jumper J22.E is used to determine which flash chips are
at which address. When J22.E is switched, addresses from FE000000
to FE7FFFFF are swapped with addresses from FE800000 to FEFFFFFF.
On the ITX, at the normal boot address (aka HIGHBOOT):
FE00_0000 HRCW
FE70_0000 Alternative U-Boot image
FE80_0000 Alternative HRCW
FEF0_0000 U-Boot image
FEFF_FFFF End of flash
On the ITX, at the low boot address (LOWBOOT)
FE00_0000 HRCW and U-Boot image
FE04_0000 U-Boot environment variables
FE80_0000 Alternative HRCW and U-Boot image
FEFF_FFFF End of flash
On the ITX-GP, the only option is LOWBOOT and there is only one chip
FE00_0000 HRCW and U-Boot image
FE04_0000 U-Boot environment variables
F7FF_FFFF End of flash

Assuming you're using BASH shell:
export CROSS_COMPILE=your-cross-compile-prefix

or:
make MPC8349ITX_LOWBOOT_config
make
6. Downloading and Flashing Images
6.1 Download via tftp:
tftp $loadaddr <uboot>
where "<uboot>" is the path and filename, on the TFTP server, of
the U-Boot image.
6.1 Reflash U-Boot Image using U-Boot
setenv uboot <uboot>
run tftpflash
where "<uboot>" is the path and filename, on the TFTP server, of
the U-Boot image.
6.2 Using the HRCW to switch between two different U-Boot images on the ITX
Because the ITX has 16MB of flash, it is possible to keep two U-Boot
images in flash, and use the HRCW to specify which one is to be used
when the board boots. This trick is especially effective with a
hardware debugger that can override the HRCW, such as the BDI-2000.
When the BMS bit in the HRCW is 0, the ITX will boot the U-Boot image
at address FE000000. When the BMS bit is 1, the ITX will boot the
image at address FEF00000.
Therefore, just put a U-Boot image at both FE000000 and FEF00000 and
change the BMS bit whenever you want to boot the other image.
Step-by-step instructions:
1) Build an ITX image to be loaded at FEF00000
make distclean
make MPC8349ITX_config
make
2) Take the u-boot.bin image and flash it at FEF00000.
tftp $loadaddr u-boot.bin
protect off all
erase FEF00000 +$filesize
cp.b $loadaddr FEF00000 $filesize
3) Build an ITX image to be loaded at FE000000
make distclean
make MPC8349ITX_LOWBOOT_config
make
4) Take the u-boot.bin image and flash it at FE000000.
tftp $loadaddr u-boot.bin
protect off FE000000 +$filesize
erase FE000000 +$filesize
cp.b $loadaddr FE000000 $filesize
The HRCW in flash is currently set to boot the image at FE000000.
If you have a hardware debugger, configure it to set the HRCW to
B460A000 04040000 if you want to boot the image at FEF00000, or set
it to B060A000 04040000 if you want to boot the image at FE000000.
To change the HRCW in flash to boot the image at FEF00000, use these
U-Boot commands:
cp.b FE000000 1000 10000 ; copy 1st flash sector to 1000
mw.b 1020 b4 8 ; modify BMS bit
protect off FE000000 +10000
erase FE000000 +10000
cp.b 1000 FE000000 10000
7. Notes
1) The console baudrate for MPC8349EITX is 115200bps.

U-Boot for Wind River SBC834x Boards
====================================
The Wind River SBC834x board is a 6U form factor (not CPCI) reference
design that uses the MPC8347E or MPC8349E processor. U-Boot support
for this board is heavily based on the existing U-Boot support for
Freescale MPC8349 reference boards.
Support has been primarily tested on the SBC8349 version of the board,
although earlier versions were also tested on the SBC8347. The primary
difference in the two is the level of PCI functionality.
http://www.windriver.com/products/OCD/SBC8347E_49E/
Flash Details:
==============
The flash type is intel 28F640Jx (4096x16) [one device]. Base address
is 0xFF80_0000 which is also where the Hardware Reset Configuration
Word (HRCW) is stored. Caution should be used to not overwrite the
HRCW, or "CF RCW" with a Wind River ICE will be required to restore
the HRCW and allow the board to enter background mode for further
steps in the flash process.
Restoring a corrupted or missing flash image:
=============================================
Details for storing U-boot to flash using a Wind River ICE can be found
on page 19 of the board manual (request ERG-00328-001). The following
is a summary of that information:
- Connect ICE and establish connection to it from WorkBench/OCD.
- Ensure you have background mode (BKM) in the OCD terminal window.
- Select the appropriate flash type (listed above)
- Prepare a u-boot image by using the Wind River Convert utility;
by using "Convert and Add file" on the ELF file from your build.
Convert from FFF0_0000 to FFFF_FFFF (or to FFF3_FFFF if you are
trying to preserve your old environment settings).
- Set the start address of the erase/flash process to FFF0_0000
- Set the target RAM required to 64kB.
- Select sectors for erasing (see note on enviroment below)
- Select Erase and Reprogram.
Note that some versions of the register files used with Workbench
would zero some TSEC registers, which inhibits ethernet operation
by u-boot when this register file is played to the target. Using
"INN" in the OCD terminal window instead of "IN" before the "GO"
will not play the register file, and allow u-boot to use the TSEC
interface while executed from the ICE "GO" command.
Alternatively, you can locate the register file which will be named
WRS_SBC8349_PCT00328001.reg or similar) and "REM" out all the lines
beginning with "SCGA TSEC1" and "SCGA TSEC2". This allows you to
use all the remaining register file content.
If you wish to preserve your prior U-Boot environment settings,
then convert (and erase to) 0xFFF3FFFF instead of 0xFFFFFFFF.
The size for converting (and erasing) must be at least as large
as u-boot.bin.
Updating U-Boot with U-Boot:
============================
This procedure is very similar to other boards that have u-boot installed.
Assuming that the network has been configured, and that the new u-boot.bin
has been copied to the TFTP server, the commands are:
tftp 200000 u-boot.bin
protect off all
erase fff00000 fff3ffff
cp.b 200000 fff00000 3ffff
protect on all
PCI:
====
This board and U-Boot have been tested with PCI built in, on a SBC8349
and confirmed that the "pci" command showed the intel e1000 that was
present in the PCI slot. Note that if a 33MHz 32bit card is inserted
in the slot, then the whole board will clock down to a 33MHz base
clock instead of the default 66MHz. This will change the baud clocks
and mess up your serial console output. If you want to use a 33MHz PCI
card, then you should build a U-Boot with #undef PCI_66M in the
include/configs/sbc8349.h and store this to flash prior to powering down
the board and inserting the 33MHz PCI card.
By default PCI support is disabled to better support very early
revision MPC834x chips with possible PCI issues. Also PCI support is
untested on the sbc8347 variants at this point in time.
