| The port was tested on Wind River System Sbc8560 board | |
| <www.windriver.com>. 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 |
