- Overview
- --------
- MPC8569MDS is composed of two boards - PB (Processor Board) and PIB (Platform
- I/O Board). The mpc8569 PowerTM processor is mounted on PB board.
- Building U-Boot
- -----------
- make MPC8569MDS_config
- make
- Memory Map
- ----------
- 0x0000_0000 0x7fff_ffff DDR 2G
- 0xa000_0000 0xbfff_ffff PCIe MEM 512MB
- 0xe000_0000 0xe00f_ffff CCSRBAR 1M
- 0xe280_0000 0xe2ff_ffff PCIe I/O 8M
- 0xc000_0000 0xdfff_ffff SRIO 512MB
- 0xf000_0000 0xf3ff_ffff SDRAM 64MB
- 0xf800_0000 0xf800_7fff BCSR 32KB
- 0xf800_8000 0xf800_ffff PIB (CS4) 32KB
- 0xf801_0000 0xf801_7fff PIB (CS5) 32KB
- 0xfe00_0000 0xffff_ffff Flash 32MB
- Flashing U-Boot Images
- ---------------
- Use the following commands to program U-Boot image into flash:
- => tftp 1000000 u-boot.bin
- => protect off all
- => erase fff80000 ffffffff
- => cp.b 1000000 fff80000 80000
- Setting the correct MAC addresses
- -----------------------
- The command - "mac", is introduced to set on-board system EEPROM in the format
- defined in board/freescale/common/sys_eeprom.c. we must set all 8 MAC
- addresses for the MPC8569MDS's 8 Ethernet ports and save it by "mac save" when
- we first get the board. The commands are as follows:
- => mac i NXID /* Set NXID to this EEPROM */
- => mac e 01 /* Set Errata, this value is not defined by hardware
- designer, we can set whatever we want */
- => mac n a0 /* Set Serial Number. This is not defined by hardware
- designer, we can set whatever we want */
- => mac date 090512080000 /* Set the date in YYMMDDhhmmss format */
- => mac p 8 /* Set the number of mac ports, it should be 8 */
- => mac 0 xx:xx:xx:xx:xx:xx /* xx:xx:xx:xx:xx:xx should be the real mac
- address, you can refer to the value on
- the sticker of the rear side of the board
- */
- .....
- => mac 7 xx:xx:xx:xx:xx:xx
- => mac read
- => mac save
- After resetting the board, the ethxaddrs will be filled with the mac addresses
- if such environment variables are blank(never been set before). If the ethxaddr
- has been set but we want to update it, we can use the following commands:
- => setenv ethxaddr /* x = "none",1,2,3,4,5,6,7 */
- => save
- => reset
- Programming the ucode to flash
- ---------------------------------
- MPC8569 doesn't have ROM in QE, so we must upload the microcode(ucode) to QE's
- IRAM so that the QE can work. The ucode binary can be downloaded from
- http://opensource.freescale.com/firmware/, and it must be programmed to
- the address 0xfff0000 in the flash. Otherwise, the QE can't work and uboot
- hangs at "Net:"
- Please note the above two steps(setting mac addresses and programming ucode) are
- very important to get the board booting up and working properly.
