57 Sandpoint X3 8240 processor board DIP switch settings, with

74 Connect the BDI2000 Cable to the Sandpoint/Unity 8240:
76 BDM Pin 1 on the Unity 8240 processor board is towards the
77 PCI PMC connectors, or away from the socketed SDRAM, i.e.:
99 Setting up the BDI2000, and preparing for TCP/IP network comms:
101 Connect the BDI2000 to the PC using the supplied serial cable.
102 Download the BDI2000 software and install it using setup.exe.
104 [Note: of course you can also use the Linux command line tool
105 "bdisetup" to configure your BDI2000 - the sources are included on
106 the floppy disk that comes with your BDI2000. Just in case you don't
107 have any Windows PC's - like me :-) -- wd ]
109 Power up the BDI2000; then follow directions to assign the IP
110 address and related network information. Note that U-Boot
111 will be loaded to the Sandpoint via tftp. You need to either
112 use the Abatron-provided tftp application or provide a tftp
113 server (e.g. Linux/Solaris/*BSD) somewhere on your network.
114 Once the IP address etc are assigned via the RS232 port,
115 further communication with the BDI2000 will happen via the
119 Making a TCP/IP network connection to the Abatron BDI2000:
121 Telnet to the Abatron BDI2000. Assuming that all of the
122 networking info was loaded via RS232 correctly, you will see
123 the following (scrolling):
125 - TARGET: waiting for target Vcc
126 - TARGET: waiting for target Vcc
130 Power up the target Sandpoint:
131 If the BDM connections are correct, the following will now appear:
133 - TARGET: waiting for target Vcc
134 - TARGET: waiting for target Vcc
135 - TARGET: processing power-up delay
136 - TARGET: processing user reset request
138 - Reset JTAG controller passed
139 - Bypass check: 0x55 => 0xAA
140 - Bypass check: 0x55 => 0xAA
141 - JTAG exists check passed
142 - Target PVR is 0x00810101
144 - Check running state passed
145 - BDI scans COP freeze command
148 - Check stopped state passed
149 - Check LSRL length passed
150 - BDI sets breakpoint at 0xFFF00100
151 - BDI resumes program execution
152 - Waiting for target stop passed
153 - TARGET: Target PVR is 0x00810101
154 - TARGET: reseting target passed
155 - TARGET: processing target startup ....
156 - TARGET: processing target startup passed
161 Erase the current contents of the flash memory:
164 Erasing flash at 0xfff00000
167 Erasing flash at 0xfff04000
170 Erasing flash at 0xfff06000
173 Erasing flash at 0xfff08000
176 Erasing flash at 0xfff10000
179 Erasing flash at 0xfff20000
184 Program the flash memory with the U-Boot image:
186 BDI>prog 0xFFF00000 u-boot.bin bin
187 Programming u-boot.bin , please wait ....
188 Programming flash passed
192 Connect PC to Sandpoint:
193 Using a crossover serial cable, attach the PC serial port to the
194 Sandpoint's COM1. Set communications parameters to 8N1 / 9600 baud.
198 Reset the Unity and begin U-Boot execution:
201 - TARGET: processing user reset request
202 - TARGET: Target PVR is 0x00810101
203 - TARGET: reseting target passed
204 - TARGET: processing target init list ....
205 - TARGET: processing target init list passed
