| 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)Tthe 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 but any 85xx cross-compiler |
| should suffice. |
| |
| 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: |
| |
| 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 |
