| 2 | Installation of U-Boot using PIBS firmware | |
| 3 | ------------------------------------------ | |
| 4 | ||
| 5 | This document describes how to install U-Boot on the Ocotea PPC440GX | |
| 6 | Evaluation Board. We do not erase the PIBS firmware but install U-Boot in the | |
| 7 | soldered FLASH. After this you should be able to switch between PIBS and | |
| 8 | U-Boot via the switch U46 SW1. Please check that SW1 is off (= open) before | |
| 9 | continuing. | |
| 10 | ||
| 11 | Connect to the serial port 0 (J11 lower) of the Ocotea board using the cu | |
| 12 | program. See the hints for configuring cu above. Make sure you can | |
| 13 | communicate with the PIBS firmware: reset the board and hit ENTER a couple of | |
| 14 | times until you see the PIBS prompt (PIBS $). Then proceed as follows: | |
| 15 | ||
| 16 | ||
| 17 | Read MAC Addresses from PIBS | |
| 18 | ---------------------------- | |
| 19 | ||
| 20 | To read the configured MAC addresses available on your Ocotea board please use | |
| 21 | the following commands: | |
| 22 | ||
| 23 | PIBS $ echo $hwdaddr0 | |
| 24 | 000173017FE3 | |
| 25 | PIBS $ echo $hwdaddr1 | |
| 26 | 000173017FE4 | |
| 27 | PIBS $ echo $hwdaddr2 | |
| 28 | 000173017FE1 | |
| 29 | PIBS $ echo $hwdaddr3 | |
| 30 | 000173017FE2 | |
| 31 | ||
| 32 | In U-Boot this is stored in the following environment variables: | |
| 33 | ||
| 34 | * Ethernet Address 0: ethaddr = 000173017FE3 (==> 00:01:73:01:7F:E3) | |
| 35 | * Ethernet Address 1: eth1addr = 000173017FE4 (==> 00:01:73:01:7F:E4) | |
| 36 | * Ethernet Address 2: eth2addr = 000173017FE1 (==> 00:01:73:01:7F:E1) | |
| 37 | * Ethernet Address 3: eth3addr = 000173017FE2 (==> 00:01:73:01:7F:E2) | |
| 38 | ||
| 39 | ||
| 40 | Configure the network interface (ent0 == emac0) | |
| 41 | ----------------------------------------------- | |
| 42 | ||
| 43 | To download the U-Boot image we need to configure the ethernet interface with | |
| 44 | the following commands: | |
| 45 | ||
| 46 | PIBS $ ifconfig ent0 192.168.160.142 netmask 255.255.0.0 up | |
| 47 | PIBS $ set ipdstaddr0=192.168.1.1 | |
| 48 | status: writing PIBS variable value to FLASH | |
| 49 | PIBS $ set bootfilename=/tftpboot/ocotea/u-boot.bin | |
| 50 | status: writing PIBS variable value to FLASH | |
| 51 | ||
| 52 | Please insert correct parameters for your configuration (ip-addresses and | |
| 53 | file-location). | |
| 54 | ||
| 55 | ||
| 56 | Program U-Boot into soldered User-FLASH | |
| 57 | --------------------------------------- | |
| 58 | ||
| 59 | Please make sure to use a newer version of U-Boot (at least 1.1.3), since | |
| 60 | older versions don't support running from user-FLASH. | |
| 61 | ||
| 62 | To program U-Boot into the soldered user-FLASH use the following command: | |
| 63 | ||
| 64 | PIBS $ storefile bin eth 0xffbc0000 | |
| 65 | ||
| 66 | This commands loads the file vis ethernet into ram and copies it into the | |
| 67 | user-FLASH. | |
| 68 | ||
| 69 | ||
| 70 | Switch to U-Boot | |
| 71 | ---------------- | |
| 72 | ||
| 73 | Now you can turn your board off and switch SW1 (U46) to on (= closed). After | |
| 74 | powering the board you should see the following message: | |
| 75 | ||
| 76 | U-Boot 1.1.3 (Apr 5 2005 - 22:59:57) | |
