The port was tested on Wind River System Sbc8560 board . U-Boot was installed on the flash memory of the CPU card (no the SODIMM). NOTE: Please configure uboot compile to the proper PCI frequency and setup the appropriate DIP switch settings. SBC8560 board: Make sure boards switches are set to their appropriate conditions. Refer to the Engineering Reference Guide ERG-00300-002. Of particular importance are: 1) the settings for JP4 (JP4 1-3 and 2-4), which select the on-board FLASH device (Intel 28F128Jx); 2) The settings for the Clock SW9 (33 MHz or 66 MHz). Note: SW9 Settings: 66 MHz 4:1 ratio CCB clocks:SYSCLK 3:1 ration e500 Core:CCB pos1 - on, pos2 - on, pos3 - off, pos4 - on, pos5 - off, pos6 - on Note: SW9 Settings: 33 MHz 8:1 ratio CCB clocks:SYSCLK 3:1 ration e500 Core:CCB pos1 - on, pos2 - on, pos3 - on, pos4 - off, pos5 - off, pos6 - on Flashing the FLASH device with the "Wind River ICE": 1) Properly connect and configure the Wind River ICE to the target JTAG port. This includes running the SBC8560 register script. Make sure target memory can be read and written. 2) Build the u-boot image: make distclean make SBC8560_66_config or SBC8560_33_config make CROSS_COMPILE=.../ELDK3.0/ppc_8xx-/ all Note: reference is made to the ELDK3.0 compiler. Further, it seems the ppc_8xx compiler is required for the 85xx (no 85xx designated compiler in ELDK3.0) 3) Convert the uboot (.elf) file to a uboot.bin file (using visionClick converter). The bin file should be converted from fffc0000 to ffffffff 4) Setup the Flash Utility (tools menu) for: Do a "dc clr" [visionClick] to load the default register settings Determine the clock speed of the PCI bus and set SW9 accordingly Note: the speed of the PCI bus defaults to the slowest PCI card PlayBack the "default" register file for the SBC8560 Select the uboot.bin file with zero bias Select the initialize Target prior to programming Select the V28F640Jx (8192 x 8) 1 device FLASH Algorithm Select the erase base address from FFFC0000 to FFFFFFFF Select the start address from 0 with size of 4000 5) Erase and Program
