------------------------------------------ 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) AMCC PowerPC 440 GX Rev.
