- ------------------------------------------
- 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:
- U-Boot 1.1.3 (Apr 5 2005 - 22:59:57)
