wdenkcc1c8a12002-11-02 22:58:18 +00001This port of U-Boot will run on a Motorola Sandpoint 3 development
2system equipped with a Unity X4 PPMC card (MPC8240 CPU) only. It is a
3snapshot of work in progress and far from being completed. In order
4to run it on the target system, it has to be downloaded using the
5DINK32 monitor program that came with your Sandpoint system. Please
6note that DINK32 does not accept the S-Record file created by the
7U-Boot build process unmodified, because it contains CR/LF line
8terminators. You have to strip the CR characters first. There is a
9tiny script named 'dinkdl' I created for this purpose.
10
11The Sandpoint port is based on the work of Rob Taylor, who does not
12seem to maintain it any more. I can be reached by mail as
13tkoeller@gmx.net.

Wolfgang Denk702e6012012-04-29 23:57:39 +000018The port was tested on a Sandpoint 8240 X3 board, with U-Boot
19installed in the flash memory of the CPU card. Please use the

115PART 3)
116 Setting up the BDI2000, and preparing for TCP/IP network comms:
117
118Connect the BDI2000 to the PC using the supplied serial cable.
119Download the BDI2000 software and install it using setup.exe.
120
121[Note: of course you can also use the Linux command line tool
122"bdisetup" to configure your BDI2000 - the sources are included on
123the floppy disk that comes with your BDI2000. Just in case you don't
124have any Windows PC's - like me :-) -- wd ]
125
126Power up the BDI2000; then follow directions to assign the IP
127address and related network information. Note that U-Boot
128will be loaded to the Sandpoint via tftp. You need to either
129use the Abatron-provided tftp application or provide a tftp
130server (e.g. Linux/Solaris/*BSD) somewhere on your network.
131Once the IP address etc are assigned via the RS232 port,
132further communication with the BDI2000 will happen via the
133ethernet connection.
134
135PART 4)
136 Making a TCP/IP network connection to the Abatron BDI2000:
137
138Telnet to the Abatron BDI2000. Assuming that all of the
139networking info was loaded via RS232 correctly, you will see
140the following (scrolling):
141
142- TARGET: waiting for target Vcc
143- TARGET: waiting for target Vcc
144
145
146PART 5)
147 Power up the target Sandpoint:
148If the BDM connections are correct, the following will now appear:
149
150- TARGET: waiting for target Vcc
151- TARGET: waiting for target Vcc
152- TARGET: processing power-up delay

167- BDI sets breakpoint at 0xFFF00100
