| 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. |

| 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. |
