| 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.: |

| | | |
| ==================== |
| |
| |
| 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 |

| |
| |
| 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 |
