Configure U-Boot
Environment variables
U-Boot can be customized in a flexible way with the use of "environment variables/scripts". The command printenv shows you most of them and their current value:
BIOS> printenv bootcmd=run jffsboot bootdelay=20 baudrate=115200 ethaddr= autoload=no ...
The command setenv is used to change these variables. For example, to set the IP address (don't do it yet):
BIOS> setenv ipaddr 192.168.0.10
The command saveenv is used to save the state of your environment variables in FLASH memory; that way they will be available at next boot:
BIOS> saveenv Saving Environment to Flash... . done Un-Protected 1 sectors Erasing Flash... . done Erased 1 sectors Writing to Flash... done . done Protected 1 sectors
Network configuration
In order to use the U-Boot's network features, you have to set the network environment variables:
BIOS> setenv netmask 255.255.255.0 (this default value should be fine in most situations) BIOS> setenv ipaddr 192.168.0.10 BIOS> setenv serverip 192.168.0.2 (the IP address of your tftp server/PC hosting the files to download) BIOS> setenv rootpath "/tftpboot/apf9328-root" (to boot Linux over NFS)
You can use the dhcp command to configure these variables from your DHCP server. You probably will have to adjust the serverip variable manually.
BIOS> dhcp dm9000 i/o: 0x15c00000, id: 0x90000a46 MAC: 00:0e:32:00:00:01 operating at 100M full duplex mode BOOTP broadcast 1 DHCP client bound to address 192.168.0.10 BIOS> setenv serverip 192.168.0.2 BIOS> saveenv
Do not forget to save your changes in FLASH, to have them available at next power up:
BIOS> saveenv
In case of troubles you can use the following U-Boot script to reset the variables to the "factory"/default settings:
BIOS> run flash_reset_env
Linux kernel installation
XX, in the following chapters, has to be replaced by your board name
- Check that your Armadeus kernel image size is smaller than the U-Boot partition (see Flash Memory Partitions for size allowances):
[armadeus]$ ls -al buildroot/output/images/
- If yes, copy it to your TFTP server directory (here /tftpboot/):
[armadeus]$ cp buildroot/output/images/* /tftpboot/
Linux kernel update script
- This is the recommended method and the easiest one. The automatic 'update_kernel' scripts downloads the image and flash it in the same go:
BIOS> run update_kernel
- To know what update_kernel script is doing you can display its content:
BIOS> printenv update_kernel
 |
Warning: If the loaded kernel image is too large, the following operation can destroy data that are stored after the partition limits (e.g. RootFS) - Check that transfered size value is less than the ones specified here Flash Memory Partitions |
Other Linux kernel update method
- Load kernel image with U-Boot through network:
BIOS> run download_kernel
or with the serial line:
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then:''
(/home/.../) C-Kermit>send /tftpboot/XX-linux.bin
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of XX-linux.bin> = .... Bytes
## Start Addr = 0x08000000
BIOS> setenv filesize <size of XX-linux.bin>
Check that transfered size value is less than the ones specified here Flash Memory Partitions
Bytes transferred = 1313216 (1409c0 hex)
- You can test your new kernel image without flashing it with; if so you will have to reload it again after test:
- Please note: The bootm command is not supported by APF51 boards yet; directly flash the kernel with the below commands instead
BIOS> bootm
- a U-Boot script exists to ease kernel image loading through Ethernet:
BIOS> run download_kernel
- After kernel image has been downloaded into RAM memory, you can flash it with:
BIOS> run flash_kernel
- If you only want to try a new kernel without flashing the kernel image you can launch it directly from RAM (U-Boot 2011.12):
BIOS> setenv bootargs console=${consoledev},${baudrate} ${mtdparts};run addubifsargs addipargs; bootm
(the kernel image you want to try must have been loaded at ${loadaddr})
- Please note: The bootm command is not supported by APF51 boards yet; directly flash the kernel with the below commands
rootfs installation
- Check that your Armadeus rootfs image size is smaller than the rootfs partition (see Flash Memory Partitions for size allowances):
[armadeus]$ ls -al buildroot/output/images/ ... [armadeus]$ cp buildroot/output/images/* /tftpboot/
- Load rootfs image with U-Boot through network:
BIOS> run update_rootfs
For large rootfs (bigger than the available RAM on your system) please use this method (not supported on the APF9328):
BIOS> nand erase.part rootfs
BIOS> tftpboot ${rootfs_addr} ${board_name}-rootfs.ubi nand
or serial line:
BIOS> loadb ${loadaddr}
''Ctrl+Altgr+\+c to access kermit command line then...''
(/home/.../) C-Kermit>send path_to_your_host_buildroot_dir/XX-rootfs.ubi
''After download is completed, you can type the c command to reconnect to the terminal:''
(/home/.../) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of rootfs>
## Start Addr = 0x........
BIOS> setenv filesize <size of rootfs>
BIOS> run flash_rootfs
- Now you should be ready to test Linux:
BIOS> boot
FPGA firmware test
The FPGA firmwares are all located in the firmware/ directory of your Armadeus view:
[armadeus]$ ls firmware/ apf_pkg BRAMTest bus_led led PS2 PS2_Opencore servo sram_test wishbone_example Xtools
You can make some trials with the firmware/PS2/ps2_top.bin file.
| |
Warning: for the APF9328, Check that your bitfile size is smaller than the firmware partition size (256KB) before trying the following commands or you may corrupt your Linux kernel FLASH partition !!! |
 |
Note: For the APF51 only binary file format work (.bin). Do not use .bit format |
- Load FPGA firmware image file with U-Boot through:
Ethernet:
BIOS> tftpboot ${loadaddr} fpgafirmware.bin
fpgafirmware.bin is of course the name of your bitfile stored in your TFTP shared directory (/tftpboot/)
then you can type the c command to reconnect to the terminal
- Test your new FPGA firmware's downloading:
BIOS> fpga load 0 ${loadaddr} ${filesize}
FPGA firmware installation
- Flash your firmware image with:
BIOS> run flash_firmware
- When you are satisfied with your firmware, you can make it "autoloaded" at power up:
BIOS> setenv firmware_autoload 1 BIOS> saveenv
| |
Note: (U-Boot 2011.12) you can manually cancel the firmware autoload using the following procedure: keeping <CTRL-C> pressed on the console and power up the board will start the board without downloading the FPGA firmware - This procedure can be helpfull if you have programmed a broken firmware |
Update U-Boot
- Check that your Armadeus U-Boot image size is smaller than the u-boot partition (see Flash Memory Partitions for size allowances) and copy all the binary images to your TFTP server directory:
[armadeus]$ ls -al buildroot/output/images/ ... [armadeus]$ cp buildroot/output/images/* /tftpboot/
U-Boot update script
- This is the recommended method and the easiest one. The automatic 'update_uboot' scripts downloads the image and flash it in the same go:
BIOS> run update_uboot
- Reset your board and check if you need to update your environment variables:
BIOS> reset U-Boot 2011.12 .. ... *** Warning - Environment version change suggests: run flash_reset_env; reset BIOS> run flash_reset_env; reset
In such a case you may have to update your network environment variables (see Configure U-Boot)
Other U-Boot update method
You can use the following commands to download U-boot in RAM:
- With Ethernet and a TFTP server:
BIOS> run download_uboot
- With Ethernet and a NFS server:
BIOS> nfs ${loadaddr} host_ip_addr:/nfs_path_to_buildroot/apfXX-u-boot{.bin|-nand.bin|.sb}
- With kermit and the serial/RS232 line
BIOS> loadb ${loadaddr}
<CTRL><ALT GR>\
c
send path_to_buildroot/apfXX-u-boot{.bin|-nand.bin|.sb}
c<ENTER>
Connecting to /dev/ttyUSB0, speed 115200
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x<size of U-Boot> = .... Bytes
## Start Addr = 0x08000000
BIOS> setenv filesize <size of U-Boot>
Then you can use the U-Boot command/script 'flash_uboot' to tranfert the new U-Boot from RAM to Flash memory:
BIOS> run flash_uboot
Advanced informations can be found at the BootLoader wiki page.
Update U-Boot, kernel and rootfs images all at once
- Copy all the binary images to your TFTP server directory:
[armadeus]$ cp buildroot/output/images/* /tftpboot/
- The automatic 'update_all' scripts downloads each image and flash it in the same go:
BIOS> run update_all
- Reset your board to check that wour board is correctly updated.

Note: When updating your board from a legacy version of Armadeus BSP you should update U-Boot first to update the environment variables before any other partition update ( see Update U-Boot) |
