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:
|
|
|
|
