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. Thomas Koeller 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: Motherboard: SW1.1: on SW1.2: on SW1.3: on SW1.4: on SW1.5: on SW1.6: on SW1.7: on SW1.8: on SW2.1: on SW2.2: on SW2.3: on SW2.4: on SW2.5: on SW2.6: on SW2.7: on SW2.8: on CPU Card: SW2.1: OFF SW2.2: OFF SW2.3: on SW2.4: on SW2.5: OFF SW2.6: OFF SW2.7: OFF SW2.8: OFF SW3.1: OFF SW3.2: on SW3.3: OFF SW3.4: OFF SW3.5: on SW3.6: OFF SW3.7: OFF SW3.8: on The followind detailed description of installation and initial steps with U-Boot and QNX was provided by Jim Sandoz <sandoz@lucent.com>: Directions for installing U-Boot on Sandpoint+Unity8240 using the Abatron BDI2000 BDM/JTAG debugger ...

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 BDI> 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 ....
