| Installation of U-Boot using PIBS firmware |
| ------------------------------------------ |
| |
| This document describes how to install U-Boot on the Ocotea PPC440GX |
| Evaluation Board. We do not erase the PIBS firmware but install U-Boot in the |
| soldered FLASH. After this you should be able to switch between PIBS and |
| U-Boot via the switch U46 SW1. Please check that SW1 is off (= open) before |
| continuing. |
| |
| Connect to the serial port 0 (J11 lower) of the Ocotea board using the cu |
| program. See the hints for configuring cu above. Make sure you can |
| communicate with the PIBS firmware: reset the board and hit ENTER a couple of |
| times until you see the PIBS prompt (PIBS $). Then proceed as follows: |
| |
| |
| Read MAC Addresses from PIBS |
| ---------------------------- |
| |
| To read the configured MAC addresses available on your Ocotea board please use |
| the following commands: |
| |
| PIBS $ echo $hwdaddr0 |
| 000173017FE3 |
| PIBS $ echo $hwdaddr1 |
| 000173017FE4 |
| PIBS $ echo $hwdaddr2 |
| 000173017FE1 |
| PIBS $ echo $hwdaddr3 |
| 000173017FE2 |
| |
| In U-Boot this is stored in the following environment variables: |
| |
| * Ethernet Address 0: ethaddr = 000173017FE3 (==> 00:01:73:01:7F:E3) |
| * Ethernet Address 1: eth1addr = 000173017FE4 (==> 00:01:73:01:7F:E4) |
| * Ethernet Address 2: eth2addr = 000173017FE1 (==> 00:01:73:01:7F:E1) |
| * Ethernet Address 3: eth3addr = 000173017FE2 (==> 00:01:73:01:7F:E2) |
| |
| |
| Configure the network interface (ent0 == emac0) |
| ----------------------------------------------- |
| |
| To download the U-Boot image we need to configure the ethernet interface with |
| the following commands: |
| |
| PIBS $ ifconfig ent0 192.168.160.142 netmask 255.255.0.0 up |
| PIBS $ set ipdstaddr0=192.168.1.1 |
| status: writing PIBS variable value to FLASH |
| PIBS $ set bootfilename=/tftpboot/ocotea/u-boot.bin |
| status: writing PIBS variable value to FLASH |
| |
| Please insert correct parameters for your configuration (ip-addresses and |
| file-location). |
| |
| |
| Program U-Boot into soldered User-FLASH |
| --------------------------------------- |
| |
| Please make sure to use a newer version of U-Boot (at least 1.1.3), since |
| older versions don't support running from user-FLASH. |
| |
| To program U-Boot into the soldered user-FLASH use the following command: |
| |
| PIBS $ storefile bin eth 0xffbc0000 |
| |
| This commands loads the file vis ethernet into ram and copies it into the |
| user-FLASH. |
| |
| |
| Switch to U-Boot |
| ---------------- |
| |
| Now you can turn your board off and switch SW1 (U46) to on (= closed). After |
| powering the board you should see the following message: |
| |
