+This port of U-Boot will run on a Motorola Sandpoint 3 development
+system equipped with a Unity X4 PPMC card (MPC8240 CPU) only. It is a
+snapshot of work in progress and far from being completed. In order
+to run it on the target system, it has to be downloaded using the
+DINK32 monitor program that came with your Sandpoint system. Please
+note that DINK32 does not accept the S-Record file created by the
+U-Boot build process unmodified, because it contains CR/LF line
+terminators. You have to strip the CR characters first. There is a
+tiny script named 'dinkdl' I created for this purpose.
+
+The Sandpoint port is based on the work of Rob Taylor, who does not
+seem to maintain it any more. I can be reached by mail as
+tkoeller@gmx.net.

+
+The port was tested on a Sandpoint 8240 X3 board, with U-Boot
+installed in the flash memory of the CPU card. Please use the
+following DIP switch settings:

+ 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

+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 ....
