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).
