PART 1)
  DIP Switch Settings:

Sandpoint X3 8240 processor board DIP switch settings, with
U-Boot to be installed in the flash memory of the CPU card:

PART 2)
  Connect the BDI2000 Cable to the Sandpoint/Unity 8240:

BDM Pin 1 on the Unity 8240 processor board is towards the
PCI PMC connectors, or away from the socketed SDRAM, i.e.:

  ====================

  | PMC conn ======  |
  |   =====  ======  |
  |                  |
  ====================


PART 3)
  Setting up the BDI2000, and preparing for TCP/IP network comms:

Connect the BDI2000 to the PC using the supplied serial cable.
Download the BDI2000 software and install it using setup.exe.

[Note: of course you  can  also  use  the  Linux  command  line  tool
"bdisetup"  to  configure  your BDI2000 - the sources are included on
the floppy disk that comes with your BDI2000. Just in case you  don't
have any Windows PC's - like me :-)   -- wd ]

Power up the BDI2000; then follow directions to assign the IP
address and related network information.  Note that U-Boot
will be loaded to the Sandpoint via tftp.  You need to either
use the Abatron-provided tftp application or provide a tftp
server (e.g. Linux/Solaris/*BSD) somewhere on your network.
Once the IP address etc are assigned via the RS232 port,
further communication with the BDI2000 will happen via the
ethernet connection.

PART 4)
  Making a TCP/IP network connection to the Abatron BDI2000:

Telnet to the Abatron BDI2000.  Assuming that all of the
networking info was loaded via RS232 correctly, you will see
the following (scrolling):

- TARGET: waiting for target Vcc
- TARGET: waiting for target Vcc


PART 5)
  Power up the target Sandpoint:
If the BDM connections are correct, the following will now appear:

- TARGET: waiting for target Vcc
- TARGET: waiting for target Vcc
- TARGET: processing power-up delay
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed
- Bypass check: 0x55 => 0xAA
- Bypass check: 0x55 => 0xAA
- JTAG exists check passed
- Target PVR is 0x00810101
- COP status is 0x01
- Check running state passed
- BDI scans COP freeze command
- BDI removes HRESET
- COP status is 0x05
- Check stopped state passed
- Check LSRL length passed
- BDI sets breakpoint at 0xFFF00100
- BDI resumes program execution
- Waiting for target stop passed
- TARGET: Target PVR is 0x00810101
- TARGET: reseting target passed
- TARGET: processing target startup ....
- TARGET: processing target startup passed
BDI>


PART 6)
  Erase the current contents of the flash memory:

BDI>era 0xFFF00000
    Erasing flash at 0xfff00000
    Erasing flash passed
BDI>era 0xFFF04000
    Erasing flash at 0xfff04000
    Erasing flash passed
BDI>era 0xFFF06000
    Erasing flash at 0xfff06000
    Erasing flash passed
BDI>era 0xFFF08000
    Erasing flash at 0xfff08000
    Erasing flash passed
BDI>era 0xFFF10000
    Erasing flash at 0xfff10000
    Erasing flash passed
BDI>era 0xFFF20000
    Erasing flash at 0xfff20000
    Erasing flash passed


PART 7)
  Program the flash memory with the U-Boot image:

BDI>prog 0xFFF00000 u-boot.bin bin
    Programming u-boot.bin , please wait ....
    Programming flash passed


PART 8)
  Connect PC to Sandpoint:
Using a crossover serial cable, attach the PC serial port to the
Sandpoint's COM1.  Set communications parameters to 8N1 / 9600 baud.


PART 9)
  Reset the Unity and begin U-Boot execution:

BDI>reset
- TARGET: processing user reset request
- TARGET: Target PVR is 0x00810101
- TARGET: reseting target passed
- TARGET: processing target init list ....
- TARGET: processing target init list passed

BDI>go

Now see output from U-Boot running, sent via serial port:

setenv ipaddr 145.17.228.81
setenv serverip 145.17.242.46
setenv gatewayip 145.17.228.1
saveenv

PART 11)
  Test U-Boot by tftp'ing new U-Boot, overwriting current:

=> protect off all
Un-Protect Flash Bank # 1
=> tftp 100000 u-boot.bin
eth: Intel i82559 PCI EtherExpressPro @0x80000000(bus=0, device=15, func=0)
ARP broadcast 1
TFTP from server 145.17.242.46; our IP address is 145.17.228.42; sending through
 gateway 145.17.228.1
Filename 'u-boot.bin'.
Load address: 0x100000
Loading: #########################
done
Bytes transferred = 127628 (1f28c hex)
=> era all
Erase Flash Bank # 1
 done
Erase Flash Bank # 2 - missing
=> cp.b 0x100000 FFF00000 1f28c
Copy to Flash... done
=> saveenv
Saving Environment to Flash...

You can put these commands into some environment variables;

=> setenv load tftp 100000 u-boot.bin
=> setenv update protect off all\;era FFF00000 FFF3FFFF\;cp.b 100000 FFF00000 \${filesize}\;saveenv
=> saveenv

Then you just have to type "run load" then "run update"

=> run load
eth: Intel i82559 PCI EtherExpressPro @0x80000000(bus=0, device=15, func=0)
ARP broadcast 1
TFTP from server 145.17.242.46; our IP address is 145.17.228.42; sending through
