1 The port was tested on Wind River System Sbc8560 board
2 <www.windriver.com>. U-Boot was installed on the flash memory of the
3 CPU card (no the SODIMM).
5 NOTE: Please configure uboot compile to the proper PCI frequency and
6 setup the appropriate DIP switch settings.
10 Make sure boards switches are set to their appropriate conditions.
11 Refer to the Engineering Reference Guide ERG-00300-002. Of particular
12 importance are: 1) the settings for JP4 (JP4 1-3 and 2-4), which
13 select the on-board FLASH device (Intel 28F128Jx); 2) The settings
14 for the Clock SW9 (33 MHz or 66 MHz).
16 Note: SW9 Settings: 66 MHz
17 4:1 ratio CCB clocks:SYSCLK
18 3:1 ration e500 Core:CCB
19 pos1 - on, pos2 - on, pos3 - off, pos4 - on, pos5 - off, pos6 - on
20 Note: SW9 Settings: 33 MHz
21 8:1 ratio CCB clocks:SYSCLK
22 3:1 ration e500 Core:CCB
23 pos1 - on, pos2 - on, pos3 - on, pos4 - off, pos5 - off, pos6 - on
26 Flashing the FLASH device with the "Wind River ICE":
28 1) Properly connect and configure the Wind River ICE to the target
29 JTAG port. This includes running the SBC8560 register script. Make
30 sure target memory can be read and written.
32 2) Build the u-boot image:
34 make SBC8560_66_config or SBC8560_33_config
35 make CROSS_COMPILE=.../ELDK3.0/ppc_8xx-/ all
37 Note: reference is made to the ELDK3.0 compiler. Further, it seems
38 the ppc_8xx compiler is required for the 85xx (no 85xx
39 designated compiler in ELDK3.0)
41 3) Convert the uboot (.elf) file to a uboot.bin file (using
42 visionClick converter). The bin file should be converted from
45 4) Setup the Flash Utility (tools menu) for:
47 Do a "dc clr" [visionClick] to load the default register settings
48 Determine the clock speed of the PCI bus and set SW9 accordingly
49 Note: the speed of the PCI bus defaults to the slowest PCI card
50 PlayBack the "default" register file for the SBC8560
51 Select the uboot.bin file with zero bias
52 Select the initialize Target prior to programming
53 Select the V28F640Jx (8192 x 8) 1 device FLASH Algorithm
54 Select the erase base address from FFFC0000 to FFFFFFFF
55 Select the start address from 0 with size of 4000
