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

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 removes HRESET
|
|
- COP status is 0x05
|
|
- Check stopped state passed
|
|
- Check LSRL length passed
|
|
- BDI sets breakpoint at 0xFFF00100
|
|
- BDI resumes program execution

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

|
|
|
|
|
|
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
