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
|

|
||
|

|
||
|
|
Note: SW9 Settings: 33 MHz

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
