| 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
 |
