1 Overview 2 -------- 3 MPC8569MDS is composed of two boards - PB (Processor Board) and PIB (Platform 4 I/O Board). The mpc8569 PowerTM processor is mounted on PB board. 5 6 Building U-Boot 7 ----------- 8 make MPC8569MDS_config 9 make 10 11 Memory Map 12 ---------- 13 0x0000_0000 0x7fff_ffff DDR 2G 14 0xa000_0000 0xbfff_ffff PCIe MEM 512MB 15 0xe000_0000 0xe00f_ffff CCSRBAR 1M 16 0xe280_0000 0xe2ff_ffff PCIe I/O 8M 17 0xc000_0000 0xdfff_ffff SRIO 512MB 18 0xf000_0000 0xf3ff_ffff SDRAM 64MB 19 0xf800_0000 0xf800_7fff BCSR 32KB 20 0xf800_8000 0xf800_ffff PIB (CS4) 32KB 21 0xf801_0000 0xf801_7fff PIB (CS5) 32KB 22 0xfe00_0000 0xffff_ffff Flash 32MB 23 24 25 Flashing U-Boot Images 26 --------------- 27 28 Use the following commands to program U-Boot image into flash: 29 30 => tftp 1000000 u-boot.bin 31 => protect off all 32 => erase fff80000 ffffffff 33 => cp.b 1000000 fff80000 80000 34 35 36 Setting the correct MAC addresses 37 ----------------------- 38 The command - "mac", is introduced to set on-board system EEPROM in the format 39 defined in board/freescale/common/sys_eeprom.c. we must set all 8 MAC 40 addresses for the MPC8569MDS's 8 Ethernet ports and save it by "mac save" when 41 we first get the board. The commands are as follows: 42 => mac i NXID /* Set NXID to this EEPROM */ 43 => mac e 01 /* Set Errata, this value is not defined by hardware 44 designer, we can set whatever we want */ 45 => mac n a0 /* Set Serial Number. This is not defined by hardware 46 designer, we can set whatever we want */ 47 => mac date 090512080000 /* Set the date in YYMMDDhhmmss format */ 48 49 => mac p 8 /* Set the number of mac ports, it should be 8 */ 50 => mac 0 xx:xx:xx:xx:xx:xx /* xx:xx:xx:xx:xx:xx should be the real mac 51 address, you can refer to the value on 52 the sticker of the rear side of the board 53 */ 54 ..... 55 => mac 7 xx:xx:xx:xx:xx:xx 56 => mac read 57 => mac save 58 59 After resetting the board, the ethxaddrs will be filled with the mac addresses 60 if such environment variables are blank(never been set before). If the ethxaddr 61 has been set but we want to update it, we can use the following commands: 62 => setenv ethxaddr /* x = "none",1,2,3,4,5,6,7 */ 63 => save 64 => reset 65 66 67 Programming the ucode to flash 68 --------------------------------- 69 MPC8569 doesn't have ROM in QE, so we must upload the microcode(ucode) to QE's 70 IRAM so that the QE can work. The ucode binary can be downloaded from 71 http://opensource.freescale.com/firmware/, and it must be programmed to 72 the address 0xfff0000 in the flash. Otherwise, the QE can't work and uboot 73 hangs at "Net:" 74 75 76 Please note the above two steps(setting mac addresses and programming ucode) are 77 very important to get the board booting up and working properly. 78
